摘要
目的:通过小鼠实验研究酪蛋白的功效及安全性,建立一种综合评价食品营养、保健功效及安全的BDI-GS新评价体系和方法。方法:对生长期ICR小鼠,通过12d低营养饲料和掺和酪蛋白饲料培育,对小鼠体质量、脏器质量/系数及其损益指数(BDI)等指标进行考察,并通过BDI的累积积分(GS)评价酪蛋白的营养、保健功效及安全性。结果:本研究表明酪蛋白综合营养功效显著,对免疫低下及Ⅱ型糖尿病有较好的预防保健功效,但对骨质有一定的负面效应,存在相应安全隐患。结论:本研究建立起一种简便、直观、综合的评价食品营养、保健功效及安全性的新体系,可以用于多类食品功效及安全的评价。
Objective： In this paper, functions and safety of casein were explored using mouse experiments to establish a novel BDI-GS comprehensive assessment system for nutrition, health promotion and safety of foods. Methods： ICR mice during growth period were fed for 12 days with maize low-nutrient diet and casein-blending diet. Body weight, organ weight, organ index and its benefit-damage index （BDI） of the mice were determined to assess nutrition, health promotion and safety of casein. Results： In the present study, casein possesses significantly comprehensive nutrition, and better health-promoting and preventive effects on immune function and Type II diabetic mellitus. Conclusion： A simple, intuitive and comprehensive system to assess food nutrition, health promotion and safety was established. This method can also be utilized to assess functions and safety of other foods.
