Two protein mixtures, A and B, based on sweet lupine, wheat flour and dried skim milk powder were formulated, bearing in mind the chemical and nutritional standards set by the National System of Health Services for protein mixtures used through the National Program of Complementary Feeding (PNAC) for preschool children. Both formulas contained 12% of sweet lupine flour, but they differed in their skim milk content, which was 15% in mixture A, and 10% in mixture B. Taking as reference value a content of 2% moisture, formula A contains 17.6% protein and mixture B, 16.4%, with a caloric content of 420 kcal/100 g for both of them. The amino acid score was 0.80 for both mixtures. The biological quality of the proteins of A and B, measured as protein efficiency ratio (PER), was 2.2 and 2.1, respectively. These values are not statistically different, although they are lower than the value of 2.5 obtained for casein (p less than 0.01).
根据国家卫生服务系统为通过国家学龄前儿童补充喂养计划（PNAC）使用的蛋白质混合物设定的化学和营养标准，配制了两种基于甜羽扇豆、小麦粉和脱脂奶粉的蛋白质混合物A和B。两种配方都含有12%的甜羽扇豆粉，但它们的脱脂奶粉含量不同，混合物A中为15%，混合物B中为10%。以2%的水分含量作为参考值，配方A含有17.6%的蛋白质，混合物B含有16.4%的蛋白质，两者的热量含量均为420千卡/100克。两种混合物的氨基酸评分均为0.80。以蛋白质效率比（PER）衡量，A和B蛋白质的生物学质量分别为2.2和2.1。这些值虽然低于酪蛋白获得的2.5的值（p小于0.01），但在统计学上没有差异。
