Unconventional protein sources: "date seeds"

G N Gabrial, F I El-Nahry, M Z Awadalla

    Zeitschrift Fur Ernahrungswissenschaft
    |December 1, 1981
    PubMed
    Summary

    Egyptian date seeds contain protein and fat but have low biological value. Biochemical analysis revealed nutritional content, but animal studies indicated poor protein quality for potential use as a food source.

    Area of Science:

    • Biochemistry
    • Nutritional Science
    • Food Science

    Background:

    • Date seeds are a potential underutilized resource.
    • Assessing the nutritional profile of date seeds is crucial for food security.
    • Egyptian date seeds offer a unique biochemical composition.

    Purpose of the Study:

    • To evaluate the biochemical composition of Egyptian date seeds.
    • To determine the protein and fat content, as well as mineral composition.
    • To assess the amino acid profile and biological value of date seed protein for potential food applications.

    Main Methods:

    • Biochemical analysis of different date seed varieties.
    • Determination of protein, fat, phosphorus, calcium, and iron content.
    • Amino acid analysis via acid hydrolysis and biological value assessment in weanling rats.

    Main Results:

    • Protein content ranged from 7.13-10.36%; fat content ranged from 6.32-9.28%.
    • Mineral analysis included phosphorus, calcium, and iron.
    • Date seed protein, when fed at 5% to rats, resulted in weight loss and was determined to be of low biological value.

    Conclusions:

    • Egyptian date seeds possess significant protein and fat content.
    • The protein quality of date seeds is low, limiting their use as a primary protein source.
    • Further research may explore processing methods to improve the bioavailability of nutrients in date seeds.
