吉尾鱼酶解蛋白粉的营养组成与评价

Nutritional Evaluation of the Enzymolytic Protein Powder of Trachurus japonicus

摘要:

对吉尾鱼酶解蛋白粉的营养成分及蛋白质的氨基酸组成等化学特性进行了较系统的研究。结果表明，吉尾鱼酶解蛋白粉粗蛋白的含量高达66.37%，蛋白质的氨基酸组成中，富含Glu（7.97%）、Asp（5.81%）、Gly（4.66%）等呈味氨基酸；蛋白质营养价高，氨基酸价为81，第一限制氨基酸是苏氨酸（1973年FAO/WHO标准）；无机盐含量丰富，尤其是Ca和Zn。

Abstract:

In this paper, the nutriments and amino acids composition of the enzymolytic protein powder of Trachurus japonicus were studied. Results showed that the powder had a high content of crude protein content (66.37%) and was in rich of tasty amino acids, such as Glutamic acid (7.97%), Aspartic acid (5.81%) and Glycine(4.66%). According to the suggested level of FAO/WHO(1973), the protein powder showed high nutrient value due to the high amino acid score (82) and threonine being of the first limiting amino acid. Besides, the powder was rich in inorganic salts, especially Ca and Zn.
