The amino acid composition of several types of dietary supplements and meal replacements was measured and compared with label values when available and to published values for egg. Calculated indicators of protein quality, such as chemical score, protein calorie:total calorie ratio, individual essential amino acid:total essential amino acid ratio, and total essential amino acid:total amino acid ratio were also compared for products, egg, and the estimated pattern of adult requirements. Predigested liquid protein products were notably lower in protein quality than other products. All non-predigested products compared favorably with egg in terms of protein quality, but were more expensive and had no advantages over regular meals in terms of protein quality as reducing aids or protein supplements.
对几种膳食补充剂和代餐产品的氨基酸组成进行了测定，并在有标签值时与标签值进行比较，同时与已公布的鸡蛋氨基酸组成值进行比较。还比较了产品、鸡蛋以及成人估计需求模式的蛋白质质量计算指标，如化学评分、蛋白质热量与总热量之比、单个必需氨基酸与总必需氨基酸之比以及总必需氨基酸与总氨基酸之比。预消化液体蛋白质产品的蛋白质质量明显低于其他产品。就蛋白质质量而言，所有非预消化产品均优于鸡蛋，但价格更高，且作为减肥辅助品或蛋白质补充剂，在蛋白质质量方面相对于常规膳食并无优势。
