Abstract:For the rational development and utilization of cassava seeds，the content of crude protein，crude fat，and starch，as well as the composition and content of amino acids，fatty acids，and mineral elements，in cassava seeds was analyzed.The results showed that the content of crude protein，crude fat，and starch in cassava seeds was 17.69%，27.37%，and 0.37%，respectively. A total of 20 amino acids were detected in cassava seeds，among which 8 essential amino acids（EAAs）accounted for 37.11% of the total amino acids（TAAs），and the ratio of EAAs to non-essential amino acids（NEAAs）was 59.02%，which was close to the ideal protein pattern（EAAs constituting approximately 40% of TAAs and exceeding 60% of NEAAs）recommended by the Food and Agriculture Organization/World Health Organization（FAO/WHO）. A total of 25 fatty acids were detected in cassava seeds，including 16 saturated fatty acids and 9 unsaturated fatty acids，the content of which was 10.81 mg/g and 29.27 mg/g，respectively.The three most abundant fatty acids were linoleic acid（18.70 mg/g），palmitic acid（6.99 mg/g），and oleic acid（5.43 mg/g）.Twenty-one mineral elements were detected in cassava seeds，and the macroelement and microelement with the highest content were Mg and Mn，which showed the content of 7 220.05 mg/kg and 1 230.02 mg/kg，respectively. In conclusion，cassava seeds demonstrated great development and utilization value for their high content of crude fat，comprehensive amino acid composition，high content of unsaturated fatty acids，and rich mineral elements.
