بررسی ترکیب شیمیایی و پروفایل اسیدهای چرب هسته خرما

The seeds of two date palm (phoenix dactylifera) cultivars, kabkab and Mordasang were analysed for their chemical composition and fatty acid profiles. The average constituents were obtained as protein 5.65%, fat 9.3%, ash. 1.25%, total carbohydrate 83/8%, acid detergent fibre 48.5%, neutral detergent fiber 67% (on a dry weight basis). Mineral analysis showed higher concentration of k, ( 300mg / 100gr dry weight) followed by P,Mg, Ca and Na. Among the microelements, Fe was higher concentration (7.5 mg/ 100 gr dry weight) followed by Mn, Zn and Cu. Gas-liquid chromatography revealed that the major unsaturated fatty acid was oleic acid (45. 36%), while the main saturated fatty acid was lauric acid (19.98%) . Myristic, palmitic, linoleic and stearic acids were also found average value being 11.12, 10.81, 8.66 and 3.39% respectively. The Result showed that date seed contained large quantities of fibre and most likely, resistant starch that may have potential health benefit. Date seed oil could be used in cosmetic, pharmaceutical and food products. Further research is needed to characterization, antimicrobial, antioxidant and other health promoting activities constituents in date seed.
