Abstract and Figures

This chapter evaluates mango seed kernel not only for its qualities as a natural food but also for the biological activity of some of its constituents, which have shown positive impacts, directly or indirectly, on health and nutrition. By its biological nature, mango seed kernel has a composition that responds to varietal and phenotypic variations. Although phenolic compounds act as anti-nutritive factors, they have recently become the subject of intense research because of their high antioxidant activity. Tannins, gallic acid, coumarins, caffeic acid, vanillin, mangiferin, ferulic acid, and cinnamic acid have been identified in the mango seed and analyzed for their antioxidant activity. Simple lipids in the mango seed kernel make up 94.8‑97.5% of the total lipids; the major constituents of these are triacylglycerols (55.6‑91.5%), followed by partial glycerides (2.3‑4%) and free fatty acids (0.8‑1.42%). Lipids are important components of food and also basic structural and functional constituents of cells; therefore, they are decisive in states of health and illness of individuals. The consumption of trans fatty acids in dietary hydrogenated fats is a worldwide public health problem because of their implications in the development of some major diseases. The physical and chemical characteristics of natural mango kernel fat make it a viable consumer alternative to high trans-fatty acid dietary fats.

INTRODUCTION
Lipids, and particularly fats and oils, are a large group of important compounds in the
structure and functioning of cells, essential in the diet for their nutritional value, and highly
desirable for their effect on the functional properties of food. Unlike oil, natural vegetable fats

are scarce, and have multiple applications. Mango kernel fat (MKF) has a composition and
physical characteristics that make it a consumer alternative to processed semi-solid fats high in
trans FA content, with serious adverse effects on human health maintenance.
BOTANICAL DESCRIPTION
Economically speaking, the mango is the most important fruit crop of the family Anacardiaceae
(Cashew or poison ivy family) in the order of Sapindales. The family contains 73 genera and
between 600 and 700 species, well-known for the presence of caustic resins in the leaves, bark,
and fruits. Several of these, including mango, may cause some type of dermatitis in humans.
The genus Mangifera contains about 60 species, of which about 15 produce edible fruits,
among them M. sylvatica, a possible ancestor of M. indica. Currently there are over 1000 known
varieties of mango, whose nomenclature is sometimes complicated because of certain
regionalisms. In the world, only a few varieties are grown on a commercial scale and traded.
The fruit has a large, central stone, flattened, with a woody cover containing a nucleus or kernel
with a single embryo, or two to five embryos (Hindu and Indo-Chinese varieties, respectively)
(Morton, 1987; Vasanthaiah et al., 2007).
HISTORICAL CULTIVATION AND USAGE
The mango has been cultivated since prehistoric times. Apparently, it is endemic to North-
Eastern India and Myanmar (Burma); possibly also to Sri Lanka (Ceylon). It was distributed
throughout South-east Asia and the Malay Archipelago, from where it spread to Africa and to
the New World through the first Portuguese and Spanish maritime routes and colonization.
The first permanent planting in Florida, however, dates from the 1860s (Vasanthaiah et al.,
2007).
Historically, its flesh has been used almost exclusively as fresh and processed fruit. Various
plant parts have been used in traditional medicine as a cure for a number of diseases. The
kernel seed has been consumed by humans and animals in some Asian groups, and, in
different preparations, has been used as a vermifuge and as an astringent in diarrhea,
hemorrhages, and bleeding hemorrhoids. The kernel fat has been administered in cases of
gastritis (Morton, 1987).
PRESENT-DAY CULTIVATION AND USAGE
At present, the mango is cultivated on a commercial scale throughout tropical and subtropical
regions, in over 3.7 million ha in the world. Mango fruit is one of the most important crops. It
is grown in over 90 countries, representing about 50% of the tropical fruits produced
worldwide. World production in 2005 was 28.5 million tonnes (Evans, 2008). India produces
nearly half of the world output, followed by China, Thailand, and Mexico; all in all, the 10
countries with the highest production of this fruit contain about 80% of the world production.
Currently, the mango is still mainly used as food. The lipids’ therapeutic properties, and
particularly the fat of the seed kernel, have been subjects of extensive research for the past
decade (Puravankara et al., 2000; Yella Reddy & Jeyarani, 2001; Abdalla et al., 2007), with
a promising outlook.
APPLICATIONS TO HEALTH PROMOTION AND
DISEASE PREVENTION
Mango seed kernel is being re-evaluated not only for its qualities as a natural food (edible,
non-toxic, with a high quality protein and amino acid score) and for the biological activity of
some of its constituents (lipid fractions and phenolic compounds identified as active anti-
oxidants and modulators of lipid metabolism) which have shown positive impacts, directly or
indirectly, on health and nutrition, but also because its fat in the natural state has shown
742

significant functional and physicochemical characteristics that could lead to it replacing fats
like cocoa butter or others that are widely used in industry and in food processing, but are now
facing serious objections because of their adverse effects on nutrition and human health.
Chemical composition and lipids of the mango seed kernel
By its biological nature, MSK has a composition that responds to varietal and phenotypic
variations. The available data are for a substantial but still minority number of commercially
important varieties from major producing regions. Table 88.1 gives the range of values most
often reported for the relevant chemical constituents of the kernel. The seed, depending on the
variety, can constitute 3e25% of the total mass of the fruit, and the kernel occupies 54e85% of
the seed; it has a moisture content of 33e86%, and the solid dried matter has proteins
(4.0e8.1%), crude fiber (1.7e7.6%), ash (1.0e3.7%), total carbohydrates (70e76%), around
0.1e6.4% of phenolic compounds, and 3.7e12.6% of crude fat. MSK proteins have high
scores of essential amino acids (78) and protein quality (177e189 adults), and an in vitro
digestibility of 26.7e29.8% (Dhingra & Kapoor, 1985, Abdalla et al., 2007).

CHAPTER 88
Mango (Mangifera indica L.) Seed and its Fats
743
Author's personal copy
Although phenolic compounds act as anti-nutritive factors, they have recently become the
subject of intense research because of their high antioxidant activity. Tannins, gallic acid,
coumarins, caffeic acid, vanillin, mangiferin, ferulic acid, and cinnamic acid have been
identified in the MSK and analyzed for their antioxidant activity (Puravankara et al., 2000;
Abdalla et al., 2007; Maisuthisakul & Gordon, 2009).
Lipids are important components of food, and also basic structural and functional constitu-
ents of cells; therefore, they are decisive in states of health and illness of individuals. MKF has
been studied regarding their yield during extraction, its toxicological safety, fatty acid and
glyceride composition, and chemical, physical, thermal and phase properties; these are
important aspects for its applicability as a substitute or a supplement to fats from other
sources. Some studies have been guided by its similarity to cocoa butter and its potential use,
mainly in the food industry or in pharmaceuticals and cosmetics.
Fat yields from the MSK fluctuate widely among varieties. Van Pee and colleagues (1981)
reported values between 6.8 and 12.6% (db) for African varieties; others, such as
Lakshminarayanan et al. (1983), found lower yields, with levels ranging from 3.7% for some
varieties from India, and Gaydou and Bouchet (1984) reported atypical ranges of 27e38% of
fat on a dry basis for Malagasy varieties. The extracted fat was solid at room temperature, and
cream-colored.
Simple lipids in the MSK make up 94.8e97.5% of the total lipids; the major constituents of
these are triacylglycerols (55.6e91.5%), followed by partial glycerides (2.3e4%) and FFAs
(0.8e1.42%). Ali and colleagues (1985) found varieties with a FFA content of up to 37% in
India. Unsaponifiable compounds, one minor component group in vegetable fats and oils
known to have significant effects on fat metabolism (Lau et al., 2005), range from 0.9 to 5.3%;
whereas the complex lipids, phospholipids and glycolipids, whose important effect has been
studied extensively in humans, are found in the order of 2.5e5.2% of the total in the MSK.
Table 88.1 also shows the amounts of unsaponifiable fractions, phospholipids, and glycolipids
in MSK, and Table 88.2 contains ranges of the reported values for the main physical and
chemical characteristics of MKF, with a saponification number between 185.6 and 198, and an
iodine value between 34.0 and 57.7.
Mango kernel fat composition
Oleic acid (18:1) is the most abundant in MKF, fluctuating between 34 and 56%; it is followed
by stearic (18:0) (24e57%) and palmitic (16:0) (3e18%) acids. Other fatty acids in smaller
quantities are linoleic (18:2) (up to 13%), and linolenic (20:0) and arachidonic acids with
smaller amounts. A few reports indicate the presence of myristic (0.7e8%) and lauric (12:0)
acids, and tridecanoic (13:0), pentadecane (15:0), palmitoleic (16:1), margaric (17:0),

nonadecane (19:0), and gondoic acids (20:1) in small and trace amounts in some varieties
(Gaydou & Bouchet, 1984).
The high predominance of oleic, stearic, and palmitic acids (over 85% of the total) has shown
that MKF is similar to other major natural fats, like cocoa butter (Theobroma cacao), Sal (Shorea
robusta), illipe butter (Shores etenoptera), Shea butter (Butyrospermum parkii), and Mowrah
(Bassia latifolia), all widely used in food processing. In the case of cocoa butter, these three fatty
acids constitute about 95% of the total, and provide a relatively simple glyceride composition;
in cocoa butters from different regions of the world, three triacylglycerols (POP, POS, and
SOS) make up more than 80% of the total, giving them unique properties.
To diversify their use, natural fats and oils are processed industrially through inter-, trans- and
direct esterification, selective or homogeneous hydrogenation, wet or dry fractionation (with
solvents or surfactants in an aqueous medium), and mixed treatments (Baliga & Shitole,
1981). These methods yield fats with the desired physical characteristics in terms of their
composition, melting points, and consistency, as well as stability against oxidation. Some, like
cocoa butter equivalents, and others used as margarine, shortenings, frying fats, etc., have,
however, presented significant drawbacks, because if they are made with severe heat treatment
the positional isomerization of the cis double bond of unsaturated FA may take place, leading
to the occurrence of trans-isomers as by-products.
Van Pee et al. (1981) found that the triglyceride composition of the MKS shows a FA distri-
bution in the glycerol molecule characterized by the location of the saturated FA in the sn-1
and sn-3 positions, the remaining sites being proportionately occupied by unsaturated oleic,
linoleic, and linolenic acids. In 10 varieties grown in Zaire, MKF oleic and linoleic acids
occupied between 85.2 and 89.9%, and 8.3 to 13.0%, respectively, of the sn-2 position in TG
molecules.
Mango kernel fat thermal behavior and polymorphism
It is known that natural fats have, in general, a complex thermal and structural behavior
derived from their TG composition. TGs and fats are characterized by multiple melting
behaviors due to their polymorphism; basically, these exhibit three different polymorphic
forms (a,b0, and b). The amounts and structure of the TGs determine their nutritional (TG
postprandial response), physical (spreadability, resistance to water/oil loss, etc.), and sensory
(melting, graininess, etc.) properties.
The thermal behavior and polymorphism of MKF, alone and in mixtures with other natural
fats, have been studied by Baliga and Shitole (1981), Yella Reddy and Jeyarani (2001), Solis-
Fuentes and Dura
´n-de-Bazu
´a (2003, 2004), and Solis-Fuentes et al. (2005), among others. In
general, such behavior has been compared with that of cocoa butter, showing that, among the
variety of obtained fats and behaviors studied, some of them closely resemble cocoa butter or
other fats widely used in the food manufacturing processes that involve the partial hydroge-
nation of vegetable oils.
Solis-Fuentes and Dura
´n-de-Bazu
´a (2004) showed that the melting curves of the MKF var.
Manila, grown widely in Mexico and other countries, are relatively simple, and show a great
resemblance to those of cocoa butter; however, the MKF fusion curve is usually wider than the
cocoa butter curve. Two stable polymorphic forms of MKF with the possibility of assuming two
other unstable forms have been identified through DSC and X-ray diffraction: the aform, with
a low melting point, and the bform, with a high melting point. Figure 88.1 shows the SFC
profiles of the MKF and cocoa butter polymorphs. The compatibility and product character-
istics of MKF blends with other fats and oils and their fractions have been analyzed.
In MKF and cocoa butter blends, it has been shown that MKF is slightly softer than cocoa butter
and has a more evident softening effect in mixtures when it comprises between 60% and 80%
of the weight. If its participation in the mixtures is small, the softening effect is negligible; if it is

Mango (Mangifera indica L.) Seed and its Fats
745

higher, the effect is compensated when the solids content is small. Additionally, MKF requires
higher temperatures than cocoa butter in order to melt.
When MKF and cocoa butter blends are taken to achieve bforms, mixture compatibility is
improved, non-softening effects appear in compositions with less than 20% of mango fat, and
a harder mixture is obtained for compositions with more than 80% of MKF. However, the
wider MKF fusion profile requires lower temperatures than cocoa butter to remain 80% solid,
and higher temperatures to melt the last 5% of solids of the fat in its pure state. Isosolid
diagrams have shown a lower compatibility between MKF and cocoa butter than between
cocoa butter and other fats such as Coberine, with isolines more parallel and horizontal during
its mixing with cocoa butter (Talbot, 1995). MKF is, however, much more compatible with
cocoa butter than milk fat, lauric fats, and hydrogenated cottonseed oil are (Solı
´s-Fuentes &
Dura
´n-de-Bazu
´a, 2004).
The analysis of the phase behavior of ternary blends of MKF, cocoa butter, and sapote mamey
(Pouteria sapota) kernel oil (SMKO) has shown that these fats can support the preparation of
mixtures with different compositions that can become like cocoa butter equivalents or other
useful mixtures for food, pharmaceutical, and cosmetic uses (Solı
´s-Fuentes & Dura
´n-de-Bazu
´a,
2003). In other studies, Yella-Reddy and Jeyarani (2001) showed that it is possible to prepare
bakery shortenings with no trans fatty acids by using MKF and mahua (Madhuca latifolia) fats
and their fractions.
ADVERSE EFFECTS AND REACTIONS (ALLERGIES AND TOXICITY)
MSK and MKF are edible, and thus far there have been no studies showing that they contain
any toxic or allergenic compounds. In times of food shortages and famine, poor people from
some producing regions have consumed boiled kernels. Rukmini and Vijayaraghavan (1984)
studied the nutritional value and toxicological safety of kernel fat by feeding rats with MKF and
groundnut oil in balanced diets with fat contents of 10%, and making multi-generation
breeding evaluations. The food efficiency ratio and growth rate of the rats fed with the MKF
diet were comparable with those of the control group. The retention of nutrients (calcium,
phosphorus, and nitrogen) was not affected adversely by MKF intake. The serum and liver total
cholesterol, total lipids levels, and liver TG type were alike in MKF and control-fed animals.
The histo-pathological evaluations of the rats’ organs showed no abnormalities.

acids, which have been proven to contribute to development of various serious diseases, and to
have adverse effects on human maintenance.

Since the human population realized how important it was to maintain overall health and the weight of disease, they have been looking for therapeutic qualities in natural environments. The use of plants having medicinal qualities for the treatment and prevention of illnesses that may have an impact on general health is known as herbal medicine. There has been a noticeable increase in interest lately in the combination of synthetic contemporary medications and traditional herbal remedies. About 80% of people rely on it for healthcare, particularly in developing nations. One important aspect of overall health is said to be oral healthcare. The World Health Organization views oral health as a crucial component of overall health and well-being. Because they are more readily available, less expensive, and have fewer adverse effects than pharmaceutical treatments, using natural medicines to treat pathologic oro-dental disorders can make sense. The current evaluation of the literature sought to investigate the range and scope of the use of herbal products and their secondary metabolites in maintaining oral health, encompassing several oral healthcare domains such as halitosis, gingivitis, periodontitis, and other oral disorders. Therefore, there are many herbs discussed in this work and their mechanism in the treatment and improvement of many oral ailments. Besides, compounds that are useful in oral treatment with their natural sources and the cases where they can be used. To prevent any possible side effects or drug interactions, a doctor's consultation is necessary before using dental medicine. Although herbal therapy is safe and with minimum side effects, it is also strongly advised to do a more thorough preclinical and clinical evaluation before using herbal medicines officially.
... The mango seed also has potential to be valorised in products, some research already proposing the extraction of the fat fraction of mango seed kernel in order to be used as biofuel or oil (Andrade et al., 2016). The fat phase is mainly composed of triacylglycerols, mostly saturated fats like stearic and palmitic acids, and some unsaturated fatty acids such as oleic acid (Oladapo et al., 2021), but also glycerides and free fatty acids (Solís-Fuentes and Durán-Domínguez-de-Bazúa, 2011). In our study, the fat content of the seed registered a higher content than what was reported for the seeds of mango varieties from Kenya (8.5%-10.4%). ...

Los subproductos de mango (SPM) generados durante su industrialización presentan gran potencial para la obtención de compuestos bioactivos (CBA) con el fin de utilizarse en el desarrollo de suplementos, alimentos funcionales y aditivos para alimentos y envases activos. El mercado de los CBA ha mostrado un crecimiento sostenido por el interés de la población en consumir alimentos saludables. Este capítulo integra información publicada sobre obtención, evaluación y aplicaciones de CBA presentes en los SPM. La cáscara de mango presenta polifenoles, carotenoides, terpenos, tocoferoles y vitaminas. Sus extractos tienen aplicaciones como ingrediente o aditivo, tanto en la producción de alimentos como en envases y películas comestibles. Los CBA de la semilla (ácidos grasos, polifenoles, carotenoides, flavonoides, terpenos, entre otros) se localizan principalmente en la almendra. Estos presentan actividad antioxidante, anti-levadura y bactericida mostrando actividad antimicrobiana similar a la del cloro, por lo que podrían utilizarse para la desinfección de agua. Al aumentar la demanda de aditivos e ingredientes bioactivos se asegura el consumo de los CBA obtenidos de los SPM; pero, la contaminación del medio ambiente por los SPM seguirá existiendo hasta que se hayan establecido procesos integrales y secuenciales para el aprovechamiento de todos los componentes minoritarios y mayoritarios presentes.

Study’s Excerpt: The ameliorative effects of mango kernel, coconut, and cottonseed oils on hydrogen peroxide-induced renal toxicity is investigated. Physicochemical properties of the oils such as peroxide, acid, saponification and iodine values, among others were analyzed. Coconut oil showed the lowest peroxide value, highest antioxidant potential and hence superior histopathological recovery in the rats. Therefore, coconut oil is the most suitable therapeutic agent for nephrotoxicity compared to mango kernel and cottonseed oils. Full Abstract: Nephrotoxicity is the rapid deterioration in kidney function due to the toxic effect of medications and chemicals. Mango, coconut and cotton seed oils are natural plant oils with various beneficial and therapeutic effect. This study was designed to investigate the potential ameliorating effect of mango kernel, coconut, and cottonseed oils on hydrogen peroxide-induced renal toxicity. The physicochemical properties of the oils were determined, and kidney markers of the blood serum, such as urea and creatine, were analysed, followed by histopathology of the kidney. The physicochemical properties showed that the oil yield was 12.06 %, 65.29 %, and 35.18 % for mango, coconut, and cottonseed oils, respectively. Mango kernel oil had a higher melting point (29.25). The specific gravity of mango kernel oil, coconut oil, and cotton seed oils was 0.89, 0.91, and 0.88, respectively. The highest flash point was recorded in cottonseed oil (302.45). Cotton seed oil had the highest moisture content (0.35). The pH of Mango kernel oil was 4.88, coconut oil 6.97 and cotton seed oil 6.15. Mango kernel oil had the highest smoke point (250.73). The lowest peroxide value was observed in coconut oil (0.52), while the highest was in cottonseed oil (3.43). Cotton seed oil had the highest acid value (6.82) and iodine value (42.16). The saponification values of mango kernel, coconut, and cottonseed oils were 142.39, 258.98, and 180.31, respectively. The unsaponifiable matter was 1.46 in mango oil, 0.42 in coconut oil, and 1.50 in cottonseed oil. The percentage of free fatty acids in mango kernel oil, coconut oil, and cottonseed oil was 2.14, 0.21, and 3.40, respectively. The levels of creatinine and urea were significantly reduced in the serum of rats that received the oils, as compared to the positive control group. The histopathological examination showed significant recovery in the group treated with coconut oil. The results of this study, however, established that coconut oil had a better ameliorating effect on kidney toxicity compared to the other oils under study, which may be due to its antioxidant properties.

Objective: The purpose of this research was to determine any connections between the characteristics of oleogels made of beeswax and the impact of mango butter. Methods: Oleogel was prepared through inverted tube methods, and optimized through oil binding capacity. Other evaluations like bright field and polarized microscopy, Fourier-transform infrared (FTIR) spectroscopy, crystallization kinetics, mechanical study, and X-ray diffractometry (XRD). The drug release kinetic studies and in vitro antibacterial studies were performed. Results: FTIR study reveals that the gelation process does not significantly alter the chemical composition of the individual components. Prepared gel exhibiting fluid-like behavior or composed of brittle networks is particularly vulnerable to disruptions in their network design. The incorporation of mango butter increases the drug permeation. In-vitro microbial efficacy study was found to be excellent. Conclusion: The studies revealed that mango butter can be used to modify the physico-chemical properties of the oleogels.

Increasing attention has been given to mango (Mangifera indica) fruits owing to their characteristic taste, and rich nutritional value. Mango kernels are typically discarded as a major waste product in mango industry, though of potential economic value. The present study aims to outline the first comparison of different mango kernel cvs. originated from different localities alongside Egypt, e.g., Sharqia, Suez, Ismailia, and Giza. Gas chromatography-mass spectroscopy (GC-MS) post silylation analysis revealed that sugars were the major class being detected at 3.5-290.9 µg/mg, with some kernels originating from Sharqia province being the richest amongst other cvs. In consistency with sugar results, sugar alcohols predominated in Sharqia cvs. at 1.3-38.1 µg/mg represented by ribitol, iditol, pinitol, and myo-inositol. No major variation was observed in the fatty acids profile either based on cv. type or localities, with butyl caprylate as a major component in most cvs. identified for the first time in mango. Regarding phenolics, Sedeeq cv. represented the highest level at 18.3 µg/mg and showing distinct variation among cvs. posing phenolics as better classification markers than sugars. Multivariate data analyses (MVA) confirmed that the premium cvs "Aweis and Fons" were less enriched in sugars, i.e., fructose, talose, and glucose compared to the other cvs. Moreover, MVA of Zabdeya cv. collected from three localities revealed clear segregation to be chemically distinct. Sharqia originated mango kernels were rich in sugars (e.g., glucose and fructose), whilst sarcosine esters predominated in other origins.

The present study aimed to evaluate the effect of Mangifera indica (mango) on dental caries. The entire plant, including the leaves, fruit, roots, and flowers, has various therapeutic characteristics used for centuries to cure various illnesses. This systematic review aimed to identify an inexpensive, simple, and effective method of preventing and controlling dental caries. The search was performed among the studies written in English, the database of abstracts concentrating on the effects of Mangifera indica (Mango) on dental caries detected in Pubmed, Scopus, Google Scholar, and Central. In total, we find 37 articles. The relevant English language articles published up to August 2022 were collected, screened, and reviewed. Search words contained “Mangifera indica” and “dental caries” or “Streptococcus mutans” or “tooth demineralization.” For our systematic review analysis, we included 3 randomized controlled trial studies studying a total of 130 people, of whom 110 were children aged 8 to 14 and 20 were adults aged 20 to 25. These experiments all employed mouthwash containing an extract from Mangifera indica. In conclusion, it has been proven in 2 separate studies that saliva’s PH will increase significantly. In addition, a reduction of S. mutants has been observed in another research. Overall, it was concluded that mango extract mouthwash is highly effective in decreasing the bacteria that can cause dental caries. however, we firmly believe that conduction of more detailed in vivo studies regarding Mangifera indica implications in dental caries treatment is essentially needed for further confirmation.

Mango (Mangifera indica L.) holds immense potential as a raw material in polymer science, influencing numerous applications. This systematic literature review, encompassing 74 studies published between 2018 and 2022, aims to elucidate the intrinsic relationship between polymers and mango. Polymers are extracted from mango plant tissues, and their substances are explored as reinforcing agents in polymeric materials. In turn, polymers are employed in the mango plant to extend shelf life. Mango by-products can serve as indicators of polymer presence. The diverse tissues and substances in mango offer considerable potential for extracting polymers, phenolic compounds, fats, and dietary fibers. Moreover, the substantial waste generated in mango production, including fruit peel, seed, stems, and leaves, can be utilized to extract economically valuable polymers. These polymers contribute to the adoption of sustainable practices in industries such as packaging, food processing, biomedical materials, wood manufacturing, and oil production. Graphical abstract

Samples of cacao butter (CB), mango seed almond fat (Mangifera indica var. Manila) (MAF), and zapote mamey seed almond fat (Pouteria sapota) (ZMAF), were analyzed for their fatty acid composition and were mixed according to a 3-factor simplex-lattice design. Mixtures were stabilized, their fusion and crystallization thermal behavior, and solid fat contents were evaluated using differential scanning calorimetry. Ternary phase behavior was analyzed with isosolid diagrams. Results showed that the main fatty acids in the fats were oleic, stearic, and palmitic acids: CB: 31.1, 35.5, and 27.8%; MAF: 37.5, 42.6 and 9.9%, and ZMAF: 50.0, 27.2 and 12.0%, respectively. Fusion behavior showed a single curve with only one maximum and one small shoulder for CB and MAF, and three maximum points for ZMAF. Crystallization was also a single curve with only one maximum for the three fats. Solid fat contents at 21.1 °C were: CB: 87.5; MAF: 68.5 and ZMAF: 6.6%. Ternary phase behavior showed that these fats can support preparation of mixtures with different compositions that could become equivalent to cocoa butter for use in alimentary, pharmaceutical, and cosmetic industries.

The kernel fat content of 16 different mango varieties collected from the Northwestern part of Madagascar island were examined. The fat content (22–54%) was determined by chloroform/methanol extraction. Investigation by gas liquid chromatography (GLC) revealed 15 fatty acids, mainly palmitic (7–12%), stearic (22–40%), oleic (41–48%) and linoleic (7–17%). Significant correlations were observed among the main fatty acids. Testing for the sterol fraction in 15 mango varieties allowed us to separate and quantitatively analyze 7 sterols by GLC. The main sterols wereβ-sitosterol (47–76%), stigmasterol (12–23%) and campesterol (7–12%). The stigmasterol/campesterol ratio (1.2:2.3) was lower in mango kernel fat than in cocoa butter. Among the 4-methyl sterol fractions, gramisterol, lophenol, obtusifoliol and citrostadienol were tentatively identified by GLC. Lupeol, cycloartenol,α- andβ-amyrins and friedelinol were tentatively identified by GLC in the triterpene alcohols fractions.

A pre-extract (PE) prepared by heating mango (Mangifera indica L.) seed kernel powder (MSKP) and ghee (1:1 w/w) to 120°C contained 430 mg% phospholipids and 224 mg% water-extractable phenolic compounds. The presence of at least eleven phospholipids in a chloroform-methanol extract of MSKP and eight water-soluble phenolic compounds in PE was confirmed. Addition of the PE to ghee at 4, 6, 8 and 10% (v/v) levels increased the phospholipid content of ghee samples over the control to 11·2, 20·9, 26·4 and 34·4 mg% of ghee and those of water-extractable phenolic compounds to 7·4, 11·1, 15·5 and 20·7 mg% of ghee, respectively. The samples of ghee with added BHA contained levels of these compounds similar to those of control samples. The antioxidant potentialities calculated from the induction periods of ghee samples stored at 80°C in comparison to control were in the order: 1·3 (0·02% BHA) < 2·6 (4% PE) < 2·9 (6% PE) < 3·1 (8% PE) < 3·2 (10% PE) suggesting that the phospholipids and the phenolic compounds of MSKP, transferred to ghee, help enhance the shelf-life by protecting against autoxidation.

The kernels of 13 different mango varieties were examined. The kernels contained, depending on variety, from 6.8 to 12.6% fat, 5.2 to 6.3% protein (Nx6.25) and 1.4 to 2.0% ash on a moisture-free basis. The fat was yellow-coloured and melted at 32.5-35.8°C. Stearic and oleic acids constitute about 85% of the total fatty acids. The ratio of stearic: oleic acids varied according to variety from 0.56 to 0.97. The remaining fatty acids are, in decreasing order, palmitic, linoleic, arachidic and lino-lenic acids. Oleic and linoleic acids represented about 88 and 10%, respectively, of the fatty acids incorporated at the sn-2-position of the triglycerides.

Seed kernels of two cultivars (Chausa and Dusheri) of mango (Mangifera indica) were analysed for chemical composition, lipid classes, fatty acid composition, amino acid profile and chemical evaluation of protein quality. The seed kernels constituted about 18% of the total fruit and had 5% protein, 6–7% crude fat, 0.19–0.44% tannins, iodine value of 34–44 and saponification number 202–213. Oleic acid (42%) and stearic acid (39%) were the principal fatty acids in the oil. The in vitro digestibility was low in these cultivars, possibly due to the presence of tannins. Sulphur-containing amino acids (methionine+cystine) and isoleucine were the limiting amino acids in Chausa and Dusheri, respectively. The essential amino acid index and protein quality index were high, thus indicating the good quality of the protein in mango seed kernel.

In this paper, some important properties, from the application point of view, of mango (Mangifera indica) almond fat var. Manila (MAF) were analyzed by differential scanning calorimetry and X-ray diffraction techniques. The thermal profile, the solid fat content (SFC) and the predominant polymorphism of MAF samples, previously characterized chemically, were studied. The results showed that this fat, from one of the main residues of mango industrialization, had a relatively simple fusion/crystallization behavior. Stabilized samples showed a simple SFC profile with one marked slope between 35 and 40  °C. Different thermal histories demonstrated the existence of at least four polymorphs. The non-stabilized samples corresponded predominantly to the formation of the crystalline &α form. The stabilized samples, tested under several time and temperature conditions, allowed the formation of two other polymorphs, which are both unstable forms and were formed during &α to β polymorphic transition. The X-ray diffraction information confirmed the presence of the less and more stable MAF polymorphs, allowing us to conclude that MAF is a β-stable fat, just as is cocoa butter.

A method was developed to extract and isolate the antioxidant principles, ie mainly phenolic and phospholipid classes, from mango (Mangifera indica L) seed kernels using organic solvents. The presence of at least six phenolic compounds and eight phospholipids in the isolates was confirmed by chromatographic techniques. A phenolic preparation and a phospholipid preparation were prepared separately by dissolving the isolated compounds from mango seed kernels in buffalo ghee. The phenolic preparation contained 9.6 mg% water-extractable phenolics, 69.5 mg% total phenolics and 6.39 mg% phospholipids. The phospholipid preparation contained 155.8 mg% phospholipids, 0.11 mg% water-extractable phenolics and 0.19 mg% total phenolics. The addition of these preparations to buffalo ghee at 5, 10 and 20% levels individually and in combination significantly increased the levels of phenolics and phospholipids respectively. Samples of buffalo ghee with added BHA contained levels of these compounds similar to that of a control sample without any other additives. The antioxidant indices calculated from the induction period of ghee samples stored at 80 ± 2 °C. in comparison with the control were, in order, 10.11 (20% phospholipid and phenolic preparation) > 8.88 (10% phospholipid and phenolic preparation) > 8.66 (20% phenolic preparation) > 6.44 (5% phospholipid and phenolic preparation) > 5.44 (10% phenolic preparation) > 4.88 (20% phospholipid preparation) > 3.00 (5% phenolic preparation) > 2.77 (10% phospholipid preparation) > 2.22 (5% phospholipid preparation) > 1.44 (0.02% BHA). This demonstrated that the phenolics and phospholipids isolated from mango seed kernel, when added jointly to buffalo ghee, helped in extending the shelf-life of ghee.© 2000 Society of Chemical Industry

The kernels of 10 different mango varieties were extracted. The physico-chemical characteristics and lipid class composition of fats were studied. The fat content of mango kernels grown under the soil and climatic conditions of Bangladesh varied from 7.1% to 10%, depending on the variety. The total lipid extracts were fractionated into lipid classes by a combination of column and thin layer chromatography (TLC). The hydrocarbon and sterol esters varied from 0.3% to 0.7%, triglycerides from 55.6% to 91.5%, partial glycerides from 2.3% to 4% and free sterol from 0.3% to 0.6%. Free fatty acids amounted to 3.0–37% as oleic; glycolipids were 0.6–1.2% and phospholipids 0.11–0.8%. The fatty acid composition of triglyceride (TG) fractions was analyzed by gas liquid chromatography (GLC). Palmitic acid varied from 7.9 molar % to 10.0 molar %, stearic from 38.2% to 40.2%, oleic from 41.1% to 43.8%, linoleic from 6.0% to 7.6%, linolenic from 0.6% to 1.0% and arachidic acid from 1.7% to 2.6%. TLC revealed the presence of lyso-phosphatidylcholine, phosphatidylcholine, phosphatidylinositol, phosphatidylethanolamine and phosphatidic acid in the phospholipid fraction.
