摘要
本文在食物氨基酸评分(AAS)的基础上,提出了“氨基酸评分差值(AASD)”。当AASD为负值时,代表限制性氨基酸,负值大小代表限制程度,用正值食物可互补负值食物,可比较直观地选择食物合理互补配对及评价膳食氨基酸互补作用的效果。本文还提出了两种食物间氨基酸互补的计算公式和多种食物混合后的通用计算方法。后者指的是“互补份”,可将主食分为若干份,每份百克,当各份均获其它食物的理想互补,则混合膳食也就实现了理想互补。本文提出的数学方法为在实际工作中评价膳食蛋白质营养价值的问题,提供了简单有效的手段,可用于食谱制订,具有简便、迅速、准确的优点。
Based on amino acid score of food, this article presents an 'Amino Acid Score Difference (AASD) ' for protein quality evaluation, the minus value of AASD representing the limiting amino acid and its number re- presenting the degree. The minus value in one food can be compensated by the positive value in another when we directly select the rational couple for amino acid complementation in diet. In addition, a calculation formula is introduced for amino acid complementation in two kinds of food or in mixed diet including many foods. It gives an effective means in evaluating the nutritional value of protein in foods and planning an ideal diet by selecting foods on the basis of amino acid complementation
