雌性阿根廷鱿鱼生殖腺营养成分分析及评价

为评估雌性阿根廷鱿鱼生殖腺的营养水平,对雌性阿根廷鱿鱼缠卵腺、卵巢以及输卵管腺的一般营养物质,氨基酸、脂肪酸组成及含量以及无机元素含量进行检测与分析。结果表明,雌性阿根廷鱿鱼生殖腺中水分含量为64.94%～73.39%,粗蛋白、粗脂肪以及多糖含量(以干重计)依次为54.61%～73.40%,2.88%～3.13%以及1.33%～2.79%。雌性阿根廷鱿鱼生殖腺中共检测出15种氨基酸,氨基酸总含量为266.33～369.01 mg/g,其中必需氨基酸含量为99.41～159.69 mg/g,占总氨基酸的比例为37.33%～43.78%,必需氨基酸与非必需氨基酸的比例为59.56%～77.87%。必需氨基酸构成比例符合FAO/WHO理想模式,属于优质蛋白源。共检测出7种脂肪酸,其中不饱和脂肪酸含量为83.77%～85.83%。常量元素K~+,Ca~(2+),Na~+和Mg~(2+)含量丰富。以上结果表明雌性阿根廷性鱿鱼生殖腺营养丰富,具有很高的开发利用价值。

Analysis and Evaluation of the Nutritional Composition of Gonads in Female Argentine Squid

In order to evaluate the nutritional level of the gonads of the female Argentine squid, the general nutrition including amino acid, fatty acid and inorganic elements were analyzed. The results showed that the content of water, crude protein, crude fat and crude polysaccharide (measured by dry weight) were 64.94%~73.39%, 54.61%~73.40%, 2.88%~3.13% and 1.33%~2.79% respectively. In the glands of female Argentine squid 15 kinds of amino acids were detected, of which in the total content was 266.33~369.01 mg/g. The content of essential amino acids was 99.41~159.69 mg/g and accounted for 37.33%~43.78%. The ratio of essential amino acids to nonessential amino acids was 59.56%~77.87%. The composition of essential amino acids is accord with FAO/WHO ideal mode, so that it is a source of high-quality protein. A total of 7 fatty acids were detected, in which the unsaturated fatty acids accounted for 83.77%~85.83%. In the gonads K+, Ca2+, Na+ and Mg2+ were also found in abundant. The experiments results suggested that the gonads of female Argentine squid were rich in nutrition with high value of development and utilization.
