Unconventional protein sources: "date seeds".
Different varieties of Egyptian date seed were evaluated biochemically. The protein content of which was in the range of 7.13-10.36%, while the fat content was from 6.32-9.28%. Phosphorus, calcium and iron were determined in all experimental samples. One variety of date seed (Samany) were used for extensive determination of the amino acids constituents by acid hydrolysis, quantitative determination of some amino acids, and evaluation of their biological value on attempt to use the seeds as new protein sources. Weanling albino rats fed on a diet of protein level 5% lost weight, but no toxic signs were observed. Analysis of blood serum of rats, for total proteins, albumin globulin ratio and free nonessential/essential amino acid protein, showed the date seed protein to be of low biological value.
