Abstract: Wheat germ is recognized as the treasure house and essence of nutrition, accounting for only 1.4%–3.9% of the dry weight of the grain. It is extremely rich in quality protein, fat and a variety of vitamins and minerals. In this study, CMC, citric acid, sugar and whole milk powder were used for formulating a wheat germ-based dairy beverage. By using one-factorat- a-time and orthogonal array design, the optimal formulation of the nutritional beverage was determined to consist of 0.08% CMC, 0.05% citric acid, 4% sugar and 4% whole milk powder.

摘要： 麦胚是小麦籽粒的营养宝库和精华,在小麦籽粒中所占比例仅为1.4％～3.9％,麦胚中含有极丰富而优质的蛋白质、脂肪、多种维生素、矿物质.本实验通过对影响麦胚乳饮料的羧甲基纤维素(CMC)添加量、柠檬酸添加量、白砂糖添加量、全脂奶粉添加量4个因素进行单因素试验和正交试验,从而确定出小麦胚乳饮料的最佳配方为:CMC添加量0.08％,柠檬酸添加量0.05％,白砂糖添加量4％,全脂奶粉添加量4％.
