Abstract Some dietary proteins cause specific effects going beyond nutrient supply.A number of proteins seem to act directly in the intestine,such as IGFs,lactoferrin and immunoglobulins.Many substances,however,are peptides encrypted in intact molecules and are released from their encrypted position by enzymes during gastrointestinal transit or by fermentation or ripening during food processing.Among food-derived bioactive proteins and peptides from plants and animals,those obtained from milk are known in particular.Numerous effects have been described after in vitro and animal trials for bioactive proteins and peptides,such as immunomodulating,antihypertensive,osteoprotective,antilipemic,opiate,antioxidative and antimicrobial.This article reviews the current knowledge of the existence of bioactive proteins and of in vitro bioactivity and the present evidence of health effects exerted by such substances or products containing bioactive compounds.For example,there is evidence for the antihypertensive effects of milk products fermented with Lactobacillus helveticus containing the tripeptides IPP and VPP,which inhibit angiotensin converting enzyme,and for osteoprotective effects by milk basic protein.There is less profound evidence on the immunomodulating effects of lactoferrin and postprandial triglyceride reduction by a hydrolysate of bovine hemoglobin.

某些膳食蛋白质会导致超越养分供应以外的特定影响.一些蛋白质一些直接作用于肠道,例如胰岛素样生长因子,乳铁蛋白和免疫球蛋白.但是也有许多物质是在通过胃肠道运输或发酵熟化食品加工过程中被从他们的加密完整分子中被释放.在来自植物和动物的食物来源的生物活性蛋白质和多肽就属于这类,那些从乳制品获得的尤其如此.这些众多的特定影响已经确认于一系列的生物活性蛋白质和多肽在人体外和动物试验中,影响包括免疫调节,抗高血压,骨保护,抗血脂,阿片,抗氧化和抗微生物.本文综述了现知的体外生物活性及该等物质的现有知识,取证于目前含有生物活性化合物的产品产生的健康影响.例如,有证据表明,用瑞士乳杆菌发酵牛奶制品含有三肽IPP和VPP 有抗高血压效果,其转换酶可以抑制血压,其牛奶碱性蛋白可以保护骨骼.也有少部分证据表明其乳铁蛋白和牛血红蛋白的水解物有对餐后甘油三酯降低的免疫调节作用.
