泥鳅粉及其加工副产品的营养学评价

Nutrition evaluation of loach powder and its processing by-products

利用常规营养测定方法,分别对泥鳅粉及其加工副产品进行营养分析与评价。结果表明:泥鳅水分含量为78.14%,泥鳅粉中蛋白质、脂肪和灰分含量分别为62.64%、8.01%和13.23%;加工副产品中蛋白质、脂肪和灰分含量分别为62.01%、7.76%和7.26%。泥鳅粉与其副产品中氨基酸组成成分一致,均含有17种氨基酸。4种呈味氨基酸含量分别为40.64%和44.98%,必需氨基酸指数(EAAI)分别为62.04和40.59,泥鳅粉构成比例符合FAO/WHO的标准,其副产品构成比例不符合FAO/WHO的标准。

The nutrition composition of loach powder and its by-products were analyzed and evaluated preliminary. The results showed that the moisture content of loach was 78.14%, the content of crude protein, crude fat, ash in loach powder were 62.64%,8.01%, 13.23%,these in by-products were 62.01%,7.76%,7.26% re- spectively. The composition of amino acids of loach powder and its by-products was basically the same, containing 17 amino acids. Total contents of 4 flavor amino acids of loach powder and its by-products were respectively 40.64% and 44.98% （dry sample percent）. The essential amino acid index（EAAI）were 62.04 and 40.59 respec- tively, and loach powder composition ratio accorded with the standers of FAO/WHO, but its by-products composition ratio didn＇t accorded with the standers of FAO/WHO.
