Abstract

Physical and chemical properties of Saidy date (Phoenix dactylifera L.) seeds from Saidy date samples were evaluated. Moisture, protein, oil and carbohydrates contents were 2.85, 13.31, 12.12 and 70.95 % date pits, respectively. The glucose fractions of date seeds was 10.46g/100g.Maltose recorded the highest value among disaccharides, Ribose was found at a low concentration of (0.95 mg/100g). Moreover, fifteen amino acids were detected in Saidy date seeds amino acid profiles revealed that contained the majority of essential amino acids: lysine, isoleucine, leucine, methionine, threonine, valine and phenylalanine. Lysine was the major amino acid of total amino acids. There are twenty-four phenolic acids were identified in date seeds among them. Pyrogallol proved the highest value (3475.95ppm). Moreover, hesperidin (56.63 mg/100g) was the highest compared with other flavonoids compounds .The most abundant fatty acids of date seeds oil were oleic, lauric, myristic, palmitic, linoleic and stearic acids.
