摘  要:
[目的]研究黄酒糟的氨基酸组成和脂类成分。[方法]分别采用氨基酸自动分析仪、薄层扫描仪和气相色谱仪对黄酒糟的氨基酸组成、脂质组成和脂肪酸组成进行研究。[结果]黄酒糟的蛋白质含量为335.2g/kg(DW),必需氨基酸的含量为111.7g/kg(DW),占氨基酸总量的36.60%,赖氨酸是黄酒糟的限制性氨基酸;黄酒糟脂肪含量为16.7g/kg(DW),不饱和脂肪酸占脂肪酸总量的57.77%,其中油酸占25.00%,亚油酸和α-亚麻酸2种必需脂肪酸占脂肪酸总量的11.27%。[结论]黄酒糟适合用于生产调味品、提取植物性蛋白和开发低脂高蛋白高纤维保健食品。

摘  要:
[Objective] The study aimed to the amino acid composition and lipid components of yellow wine lees.[Method] Amino acid composition,lipid composition and fatty acid composition of yellow wine lees were measured by automatic amino acid analyzer,thin layer chromatography and gas chromatography,respectively.[Result] The protein content of yellow wine lees was 335.2 g/kg(DW),the essential amino acid content was 111.7 g/kg(DW),accounting for 36.60% of total amino acids.Lysine was the limiting amino acid.The lipid content was 16.7 g/kg(DW).Unsaturated fatty acids accounted for 57.77% of total fatty acids including 25.00% oleic acid,11.27% essential fatty acids(linoleic acid and α-linolenic acid).[Conclusion] Yellow wine lees was suitable for producing seasonings,extracting plant protein and developing healthy food with low fat,high protein and high fiber contents.
