CHARACTERIZATION OF MORINGA (BEN) SEED OILGROWN IN EGYPT

Abstract: Ben (Moringa) is a sub tropical plant grown in upper Egypt and Sinai for many decades and the most known species are M. oleifera and M. peregrina. Nowadays, much attention was oven to the nutritional value of Moringa plant and there is an increasing interest in spreading these species in the newly reclaimed land in an attempt to decrease the gap in oil production.
The percentage of hulls to kernels and percentage of oil differed in the two tested species, being represented 45.65, 52.27% and 27.70, 42.58% of total seed weight of M. pregrina and M. oleifera, respectively. Total pigments, phenols, flavonoids, carotenoids and vitamin C content were determined using the colorimetric method in seeds (hulls and kernels) of both M. pregrina and M. oleifera.
Oil from the two species was extracted using four different methods; cold press (CP), solvent extraction using either n-hexane (H) or with a mixture of chloroform: methanol (50:50) (C:M) and water extract (W). Physical characteristics; density specific gravity, and refractive index (at 25C) were determined. Chemical characteristics i.e. peroxide and iodine values, unsaponifiable matters, absorption at 232 nm and 268 nm and tocopherols (by HPLC) were also determined. Fatty acids profile of the extracted oils using four extraction methods were followed by GLC and their resistance toward oxidation at 100°C was measured by Rancimat method. High resistance
