Abstract :
[en] The almond tree (Prunus dulcis) is a drought tolerant crop. Being a rustic plant, almond tree can grow in varied climates (1) and frequently used in dryland farming. The ability of almond trees to tolerate summer heat and winter cold and to endure high water deficits are prove of its efficiency in valorization of semi-arid areas. For all these reasons, a new project of almond plantation (Profao) is implemented for valorization of marginal sols in eastern region of Morocco with the aim of helping population to have a stake in their rural economies. In this region, self-consumption constitute the important part of the almond production, which has high costs and lower profitability. Almonds are a good source of vegetable oil, protein and mineral bio elements. Many information on almond constituents and almond crops are available in Europe and USA (2), few references occur in the bibliography concerning almond crop in Morocco but there is no data on physicochemical characterization of almond and derivatives products. Therefore, in this preliminary study, sweet almond oils of four varieties (Feragnès, Ferraduel, Marcona and Fournat) were extracted mechanically and by soxhlet. Results showed that yield of oil from almonds crushed mechanically varies between 46 and 60 % of the dry mass and comparable profiles of fatty acid (FA) and triglycerides for the analyzed almond oils. The two main FA of those almond oils are unsaturated oleic acid (56-74%) and linoleic acid (19-25%); followed by Palmitic acid (2.5-8%), Palmitoleic and stearic acids, that range between 0.2-2.8% and finally minor FA (Linolenic & Arachidic acids) with quantities less than 0.1%.
