Abstract

 

The composition of roselle seed from oil, protein, ash, fiber, fatty acids and amino acids was determined and compared in three cultivars in order to use it as an unconventional nutritional source. Aswan cv. occupies the highest significant rank in protein (31.51), oil (23.70) and fiber (4.87%) contents. Aswan and Sewa cvs. had the highest significant unsaturated fatty acid composition, especially oleic and linoleic acids, with oleic acid having values of 36.22 and 33.34% and linoleic acid, 14.95 and 15.10% values. Protein of Aswan cv. had the highest significant values of seven essential amino acids and four non-essential amino acids, especially lysine and phenylalanine.

 

Key words: Amino acids, fatty acids, nutrition, oil, protein, roselle, unconventional crops.
