Analysis and evaluation of nutritional composition of the whole viscera of Sanguinolaria acuta

Nutritional components of the whole viscera of Sanguinolaria acuta were analyzed and evaluated.General nutrients, amino acid compositions, fatty acid compositions and mineral contents were investigated.The results showed that the content of crude protein in dry basis was 68.6%, the total sugar was 11.2%.The total content of the amino acids from protein was 55.82%, and essential amino acids which accounted for 38.7% of the total amino acids.Valine was the first limiting amino acid;the score of amino acid was 57.The crude fat level was low and SFA∶ MUFA∶ PUFA=1.3∶ 1∶ 1.7, while mineral contents were high, especially Fe (167mg/kg) .In comparison with hygiene criterions, the content of Pb was higher, and Cu, As, Cd and Hg were lower.Therefore, it showed that there were higher nutritive value and better flavor character in the whole viscera of Sanguinolaria acuta.
