Analysis and Assessment of Muscle Nutritive Composition Between Female and Male Neosalanx brevirostris Pellegrin
摘要
Abstract
The contents of nutritional composition in muscles of female and male Neosalanx brevirastris Pellegrin were measured and analyzed. The results showed as follows: compared with the female, crude protein in fresh muscle of male Neosalanx brevirostris Pellegrin were significantly higher (P< 0.05); the female Neosalanx brevirostris Pellegriw contained very significantly lower crude ash than the male (P<0.0\); there was no significant difference in moisture and crude fat contents in fresh muscle between female and male ( P>0.05). Both female and male Neosalanx brevirostris Pellegrin had 18 kinds of amino acids , but compared with the female, the contents of most amino acids in muscle of male were significantly higher (P<0.05). The contents of delicious amino acids of female and male Neosalanx brevirostris Pellegrin were 26.43% and 30.47% respectively; the raio of total delicious amino acids to total amino acids were 35.23% and 35.83%. According to the amino acids score( AAS), the first limiting amino acid of female and male Neosalanx brevirostris Pellegrin was Valine and the second was Tryptophan. But according to the basis of chemical score( CS ), the first limiting amino acid of female and male Neosalanx brevirostris Pellegrin was Tryptophan and the second was Valine.Theessential amino acids index ( EAAI) of female and male Neosalanx brevirostris Pellegrin were 89.51 and 93.13 respectively; it was clear that the constitutional rate of the essential amino acids met the Food and Agriculture Organization of the United Nations /World Health Organization (FAO/WHO)Standards. The contents of total amino acids .essential amino acids .flavour amino acids and DHA in the muscle of female Neosalanx brevirostris Pellegrin were significantly lower than the male Neosalanx brevirostris Pellegrin's(P< 0.05), respectively. In conclusion, the male Neosalanx brevirostris Pellegrin was a kind of safe and higher nutritional quality fish, which has better edible value and health care functions.关键词
