Momordica grosvenorii saponin (MGS), as a promising dietary supplement with remarkable biological properties, has poor stability under acidic conditions and thus hinders its application in functional foods. In this study, capsules of chitosan and sodium alginate were successfully prepared to enhance the stability of MGS. The optimized parameters for preparing MGS capsules were established. Sodium alginate of 20.8 mg/mL and triplication of MGS powder were added to chitosan of 4 mg/mL and calcium chloride of 10 mg/mL at a volume ratio of 3:1, stirring at 1000 r/min for 30 min to form the capsules. In this case, the fresh particles averaged 1687 μm with an encapsulation efficiency (EE) of 80.25% MGS. The capsule tolerated acidic environments better, and in vitro MGS could be controlled to release in a stimulated gastrointestinal tract system. The antioxidant activity and delayed release of MGS could be achieved by microencapsulation of chitosan/sodium alginate. Moreover, one drink containing 19 mg/mL MGS was successfully developed for the fruit.
... Still, some results in the literature were given here. For example, Yilmaz et al. (2015) indicated that total phenolic content of wild pear (Pyrus elaeagnifolia Pall.) varied from 42.79 to 119.14 mg GAE/100 g. In other study, DPPH scavenging activity and total phenolic content of hawthorn extracts were 91% and 157.8 ± 3.7 mg/g, respectively (Hosseinimehr et al. 2008). ...

In this study some bioactive properties of extracts of wild pear (Pyrus elaegnifolia), hawthorn (Crataegus spp.), oriental hackberry (Celtis tournefortii), oleaster (Elaeagnus angustifolia), Japanese crabapple (Malus floribunda), rosehip (Rosa canina), pedunculate oak (Quercus robur), service tree (Sorbus domestica) and firethorn (Pyracantha coccinea) wildly growing in Turkey were investigated. The fruit extracts were analysed in terms of total phenolic content (TPC), antioxidant activities (DPPH and phosphomolybdenum methods) and antimicrobial activity. In the results, TPC, IC50 value of DPPH and IC50 value of phosphomolybdenum for pedunculate oak were 454.35 mg GAE/g d.w., 340.52 mg AAE/g d.w. and 96.52%, respectively. Service tree and firethorn exhibited the lowest TPC (4.11 mg GAE/g d.w.) and IC50 value of DPPH (53.32 mg AAE/g d.w.), respectively. Moreover, antimicrobial activity of oleaster was 2.46%. The hackberry fruit extract had no inhibitory effect against the tested microorganisms whereas pedunculate oak extract (with 10%) had the highest inhibitory effect against Aeromonas hydrophila. Additionally, all the fruit extracts had no antimicrobial activity against the Saccharomyces cerevisiae. In conclusion, wild edible fruit extracts can be used as bioactive material due to their antioxidant and antimicrobial activity in food industry and human nutrition.
... Wild pear is highly adapted to dry climate conditions. Fully xerophyte wild pear trees with a deep rooting system have a potential to be used as rootstock especially in commercial pear culture (ÖZÇAĞIRAN et al., 2005;YILMAZ et al., 2015). Wild pear fruits in their habitats are freshly consumed or dried-consumed or they are used in brine and fruit syrup production (YERLITURK et al., 2008). ...
... Increasing world population have resulted in reduction of natural resources and put some natural species under danger (SENGUL et al., 2014;SNEP and CLERGEAU, 2020). Wild pears are among these endangered species (YILMAZ et al., 2015). Besides, for plant breeding purposes, genetic resources should be collected and taken under protection (SIMSEK et al., 2010b;KOCSISNÉ et al., 2020). ...

Turkey with diverse ecologies is among the unique countries in terms of plant species and diversity. Among these plant species, naturally growing wild pears (Pyrus elaeagrifolia Pall.) are resistant to chlorosis and drought and could be used in rootstock development programs. In present study, genetic diversity in 96 wild pear genotypes collected from 11 different provinces (Kayseri, Ankara, Kahramanmaraş, Adana, Nevşehir, Konya, Isparta, Denizli, Uşak, Afyonkarahisar, Eskişehir) and regions of Turkey through selection was investigated with the use of SSR (Simple Sequence Repeat) molecular marker system. Present analyses carried out in ABI (Applied Biosystem) 3500 capillary electrophoresis system revealed 93 scorable and all polymorphic bands, thus polymorphism rate was 100%. In UPGMA (Unweighted pair group method with arithmetic mean) dendrogram of wild pear genotypes, similarity index values varied between 0.20-0.83 and a large variation was observed among the genotypes. Present finding may have significant contributions to further studies to be conducted for preservation of gene sources and breeding of wild pear genotypes.

Apple (Malus × domestica Borkh) is one of the most important fruit produced and consumed in all over the world. The large number of apple cultivars reflects also a broad range of variability in the quality traits. “Fruit quality” is a dynamic concept changing on the basis of the consumer needs and perceptions that reflect sociocultural evolution. Almost all the characteristics determining apple quality can be measured or classified. The modern apple cultivation is probably the result of interspecific hybridization and cross-breeding programmes were mostly applied to improve new varieties with desirable quality. For this purpose, in this study, it was aimed to detect some pomological and fruit characteristics such as aroma compounds, sugars, organic acids and vitamin C contents in 83 F1 individuals created by crossing ‘Kaşel-41’ (female parent) and ‘Williams Pride’ (male parent) cultivars. Flavor components which have a high importance for fruit quality were detected by using HS-SPME/GC/MS (Headspace Solid Phase Micro Extraction Gas Chromatography/Mass Spectrometry) techniques. HPLC (High-Performance Liquid Chromatography) technique was applied for the sugars, organic acids, and vitamin C analyses. According to the obtained results a great differences were detected among apple individuals. Concerning their chemical composition, the main sugar constituent of fruits was fructose ranging from 1.89 to 6.67%. Malic acid was the major organic acid reaching the maximum value of 7.77% followed by succinic acid. Moreover, a total of 11 different aldehydes, 24 esters, 10 acids, 12 alcohols, 3 ketones, and 3 terpenes were identified and quantified in F1 individuals and their parents.

As a local medicine and food, wampee fruit, with abundant bioactive compounds, is loved by local residents in Southern China. Titratable acid (TA), total sugar (TS), and total phenolic and flavonoid contents were detected, and phytochemical profiles and cellular antioxidant activities were analyzed by the HPLC and CAA (cellular antioxidant activity) assay in five sweet wampee varieties and five sour wampee varieties. Results showed that the average TS/TA ratio of sweet wampee varieties was 29 times higher than sour wampee varieties, while TA content was 19 times lower than sour wampee varieties. There were much lower levels of total phenolics, flavonoids, and antioxidant activities in sweet wampee varieties than those in sour wampee varieties. Eight phytochemicals were detected in sour wampee varieties, including syringin, rutin, benzoic acid, 2-methoxycinnamic acid, kaempferol, hesperetin, nobiletin, and tangeretin, while just four of them were detected in sweet wampee varieties. Syringin was the only one that was detected in all the sour wampee varieties and was not detected in all sweet wampee varieties. Correlation analysis showed significant positive correlations between TA with phenolics, flavonoids, and total and cellular (PBS wash) antioxidant activities, while there were significant negative correlations between TS/TA with phenolic and cellular (no PBS wash) antioxidant activities. This suggested that the content of titratable acid in wampee fruit might have some relationship with the contents of phenolics and flavonoids. Sour wampee varieties should be paid much attention by breeders for their high phytochemical contents and antioxidant activities for cultivating germplasms with high health care efficacy.

Bread, one of the basic nutritional and staple foods for many societies today, is almost as old as the history of humanity. Loaf, yufka phyllo, bazlama-flatbread and tandır-tandoori varieties of bread are widely made in Turkey. Inherited from our ancestors, yufka is frequently made throughout Turkey. Wild pear, which is also known by names such as “ahlat, gray pear, etc.”, which grows in mountainous regions in Konya, was used in making phyllo bread, especially in times of famine. In this study, pear bread made in Konya, especially in the mountainous parts, was investigated. In this study, which is a qualitative research method, 14 semi-structured questions about the production and history of pear bread were asked to 13 people (8 women and 5 men) selected by purposive sampling method in May 2021. Pear bread can be used as an important gastronomic element and it is an important bread type in terms of health thanks to its bioactive compounds, and also its taste and aroma. It can be used to promote the region. Today, pear flour is also used in cake making. In this context, it is thought that different bakery products can be produced by using pear flour. ÖZET Günümüzde birçok toplum için temel besin ve temel gıdalardan biri olan ekmek, neredeyse insanlık tarihi kadar eskidir. Türkiye'de somun, yufka, bazlama ve tandır ekmekleri yaygın olarak yapılmaktadır. Atalarımızdan miras kalan yufka, Türkiye'nin her yerinde sıklıkla yapılır. Konya'nın dağlık bölgelerinde yetişen “ahlat, boz armut vb.” gibi isimlerle de anılan yabani armut, özellikle kıtlık dönemlerinde yufka ekmek yapımında kullanılmış olup halen bu gelenek devam ettirilmektedir. Bu çalışmada Konya'da özellikle dağlık kesimlerde yapılan armut ekmeği incelenmiştir. Nitel bir araştırma yöntemi olan bu çalışmada, amaçlı örnekleme yöntemiyle seçilen 13 kişiye (8 kadın ve 5 erkek) Mayıs 2021'de armut ekmeğinin üretimi ve tarihçesi ile ilgili 14 yarı yapılandırılmış soru sorulmuştur. Önemli bir gastronomik unsur olduğu düşünülen armut ekmeği, kendine has tat ve aroması, içerdiği biyoaktif bileşikler ile sağlık açısından önemli bir ekmektir. Bölgenin tanıtımı için kullanılabileceği düşünülmektedir. Günümüzde armut unu kek yapımında da kullanılmaktadır. Bu bağlamda armut unu kullanılarak farklı unlu mamüllerin üretilebileceği düşünülmektedir.
