国产大豆组织蛋白混合膳食人体表观消化率的研究

<正> 由于人类蛋白质食物资源比较缺乏和防治心血管系统疾病的需要,近年来植物蛋白质的开发利用日益引起人们的重视。其中主要是大豆蛋白质。国外已经形成商业性生产销售的大宗大豆蛋白制品,主要有脱脂大豆蛋白粉、分离大豆蛋白和浓缩大豆蛋白等。美国、日本分别从六十年代开始市销。我国在近2～3年内才开始研制。

A STUDY OF HUMAN DIGESTIBILITY OF MIXED DIETS CONTAINING TEXTURED SOYBEAN PROTEINS MADE IN CHINA

This experiment was made in May and June, 1982. Nine male adults took two test diets, of which all ingredients were the same, except one with textured soybean protein and the other rolled bean curd sheet. The quantities of the test diets were recorded. During the test periods no other food was allowed and the nutritive values in the test diets were maintained to meet the subjects' physiological needs. They were divided into two periods, each consisting of six days: three for preparations, three for experiments.The samples of the diets and the volunteers' faeces were analysed for the contents of water, dry matter, total nitrogen, crude fat, ash and fiber. The urine nitrogen was analysed. The apparent digestibilities of dry matter of the test diets were 94.25 and 94.16%, total nitrogen 83.67 and 83.56%, and crude fat 91.13 and 91.32% respectirely.This result suggests that there is no significant difference between the apparent digestibilities of textured soy bean protein and rolled bean curd sheet protein.
