瓜菜类蛋白质在我国农村人民膳食蛋白质中占有一定的比重,故无论从人民正常生活或从备战备荒着眼,对瓜菜及某些山区食物如栗、榛子、核桃等的蛋白质营养价值进行评价均具有一定意义。以往认为Mitchell的氮平衡法评定食物蛋白质营养价值比较精确,但所需时间、人力、物力都较多。Osborne和Mendel的蛋白质效价比值法(生长法)比较简单,
The melon vegetable protein occupies a certain proportion in the dietary protein of the rural people in our country. Therefore, whether from the normal life of the people or from the point of preparation for preparation, the protein nutritional value of vegetables and certain mountainous foods such as chestnut, hazelnut and walnut are evaluated Has some significance. In the past that Mitchell nitrogen balance method to assess the nutritional value of food protein more accurate, but the time required, manpower and material resources are more. Osborne and Mendel’s protein titer method (growth method) is relatively simple,
