Rapeseed (Brassica napus L.) is the world's second-largest oilseed crop after soybean. It contains functional compounds, including fatty acids and phenols, which are known for their health and nutritional benefits. In Morocco, rapeseed was introduced as a promising oilseed crop that has shown good adaptation and great potential. Six genotypes were...

Valorisation of Argan oil requires the precise identification of different provenances markers. The concentration of tocopherol is regarded as one of the essential parameters that certifies the quality and purity of Argan oil. In this study, 39 Argan samples from six different geographical origins (Safi, Essaouira, Agadir, Taroudant, Tiznit, and Si...

The prickly pear (Opuntia spp.) is an important plant in the economies of arid and semiarid areas, considering its low agronomic requirements and high water use efficiency. Characterizing the chemical composition of this plant will open new avenues for food, pharmaceutical, and cosmetic applications. In this context, this study examined the physica...

Quality control and traceability of Argan oil requires precise chemical characterization considering different provenances. The fatty acid profile is an essential parameter that certifies the quality and purity of Argan oil. In addition, stable isotopes were recently shown to be accurate as an indicator for geographical origin. In this study, fatty...

Pomegranate seeds (Punica granatum L.) are quantitatively and qualitatively a relevant agri-food by-product which is rich in molecules beneficial to human health. In order to valorize this resource, this study aims to evaluate and to compare, for the first time, the characteristics of fruit seeds and seed oils of ten pomegranate cultivars grown in...

Six wild olive subspecies (Olea europaea L.) are currently recognised globally, with two taxa cooccurring in the argan tree area in Central West Morocco: the widespread Mediterranean subspecies europaea var. Sylvestris (the so-called oleaster) and the microendemic subspecies maroccana. Despite its taxonomic and ecological importance, the chemical c...

Lipid oxidation and adulteration have a negative impact on functionality and notoriety of foods especially vegetable oils and cause economic losses. The present study investigates the control of two commercial quality aspects of prickly pear seeds oil (PPSO): oxidative stability during storage and detection of adulteration. Peroxide index, specific...

Pistacia lentiscus is an aromatic member of the Anacardiaceae family, endemic to the Mediterranean regions, which produces red and black oleaginous seeds in maturity. Our study focuses on the characterization of Pistacia lentiscus seed oils from three localities of High Atlas Mountain in the Azilal region of Morocco. Our results showed a very appre...

This work aims at evidencing the quality and chemical composition of extra virgin olive oils according to stages of maturity and in relation to the geographical location of olives. Three different olive cultivars (Moroccan Picholine, Languedoc Picholine, and Frantoio), grown in two different locations in Morocco (Errachidia and Marrakech), were stu...

Olive is a long-living perennial species with a wide geographical distribution, showing a large genetic and phenotypic variation in its growing area. There is an urgent need to uncover how olive phenotypic traits and plasticity can change regardless of the genetic background. A two-year study was conducted, based on the analysis of fruit and oil tr...

Morocco has an extremely geomorphological, topographical and bioclimatic diversity; hence the origin of the diversity of ecosystems. The aim of this study was to know the yeast diversity from Olea europaea at two Moroccan olive habitats, orchards and crushing unit of Moroccan Picholine olive variety. This study focused on two different locations fr...

Physico-chemical, functional and antioxidant capacities of 26 oat (Avena sativa L.) lines and cultivars were investigated. The results showed that the contents were considerably variable within samples, starch concentration (44,83-63,79%), carbohydrate (42,08-62,65%), protein (9,67-17,44%), fat (3,06-10,96%), β-glucan (1,37-6,05%) and ash (1,22-5,3...

Penicillium species are well represented among the isolates found in the various olive analyzed samples from two región in Morocco. The olives picked at the crushing units of the Marrakech-Safi region are characterized by a high fungal diversity: 17 species were isolated from olives belonging to this zone. Only 7 among 17 species were isolated from...

In the mountainous areas of Al Haouz in the High Atlas, the olive is centennial especially in the terroir of AMIZMIZ. Like the other olive-growing regions of Morocco, This tree represents in this area a primordial role in the income of farmers. The present work tackles the evaluation of olive oils' quality produced by four olive oil's cooperatives...

The olive sector participates in the self-sufficiency of the country in food fluid vegetable oils, up to 16 %; it accounts for 5% of the Gross Domestic agricultural Product (GDP), and 15 % of the food exports. With the implementation of the Moroccan Green Plan (MGP), this sector was given a great importance especially regarding the extension of cul...

The oils are considered a primary source of raw materials sought in cosmetics. To enhance the production of new products and by local produce bases Moroccan oils, also saw the emergence of the cosmetics industry after semi-industrial units, we studied in this present work, the characterization the oils from the seeds of various local genotypes juju...

L’objectif du présent travail est de contribuer à la recherche d’une typicité de la viande caprine de la Région d’Immouzer Marmoucha. Il combine trois parties dont l’étude des acides gras, celle liée à la dégustation et enfin celle liée à la qualité hygiénique. Les profils d’acides gras au niveau du muscle, de la queue et des dépôts adipeux ont été...

Bouchouk Laghlid, Bouchouk Rguigue, Bakhboukh Beldi, Bouchouika and Berri Meslal are some of the olive autochthon varieties in the North of Morocco. These varieties have morphological characteristics distinguishing them from the dominating local cultivar "Picholine marocaine". However, the evaluation of some oil quality and purity parameters isn't...

This study was conducted to evaluate the quantitative and qualitative effects of partial rootzone drying (PRD) irrigation on olive trees and their fruit and oil quality. Olive trees of the Moroccan Picholine variety were grown under arid conditions in Marrakech, and exposed to four irrigation treatments: Control (irrigated with 100 % of the crop ev...

The evolution of the maturity index during the ripeness of olives from the Moroccan Picholine variety did not show any significant variation before the middle of September. After this date it began the growing and reached the maximum value (4.7) at the middle of January. The weight of olives increased continuously from June to November, and remaine...

From june to february 13 olive samples from Moroccan Picholine olive trees were collected. The oils from the first samples have high acidity levels (>1%). But this latter decreases rapidly then stabilizes between 0.36 and 0.44%. The evolution of the total fatty acids shows a relatively high rates of C18:3 in the first samples. These proportions dec...
