摘 要
本文主要概述牛初乳的历史、功能性组份,营养学专家对牛初乳的生理功能评价,以及牛初乳的食品和生物加工特性,并探讨了牛初乳功能性食品开发的相关问题、对策和前景。对不同泌乳期初乳进行初步研究,发现只有3天以内(最好2天以内)初乳才具有较大开发价值。另外对初乳一般理化性质研究发现,初乳的密度、PH值、酸度等都不同于常乳;随着泌乳期的延长,其初乳各方面指标逐步接近常乳。对初乳热稳定性研究发现,泌乳期越短、开发价值越大的初乳,其热稳定性越差。乳品工业的迅速发展,为食品工业提供了宝贵的牛初乳资源。我国约有乳牛420万头,除喂养牛犊外,富余牛初乳应在8~10万t以上。为了适应现代社会需求,推动乳品工业发展,研究开发牛初乳功能性食品策略,必须了解牛初乳的基本贮运和加工特性。在常乳和乳清中也含有牛初乳功能性组分,有助于开发这些潜在的功能性食品资源不同泌乳期的牛初乳为原料,测定不同泌乳期,不同的PH值以及添加磷酸盐、柠檬酸盐、蔗糖、钙离子、EDTA、卡拉胶等食品中允许添加物质的热凝固时间(HCT)对初乳热稳定性的影响。

Abstract
This text mainly says the history, the function an of the cow colostrum all.The dietetics expert's the physiology function evaluation to the cow colostrum, and the food and living creatures of the cow colostrum process the characteristic, and inquiried into the related problem, counterplan and foregrounds of the cow colostrum function food development.Expect the colostrum to carry on the first step research to the different milk of , the detection onlies have 3 days to compare to develop the value greatly in( best 2 days in) the colostrum ability.Discover to the general physics and chemistry property research of colostrum moreover, the density of the colostrum, PH value, acidity etc.s often all differ from milk;Along with the extension of the milk period, its colostrum the everyone often face the index sign to near to gradually milk.To the colostrum hot stability research detection, the milk period is more short, the development is worth the more big colostrum, its hot stability is more bad.The quick development of the milk article industry, provided the precious cow colostrum resources for the food industry.The our country about has 4,200,000 of milk cow, in addition to feed keeping the cow , rich remaining cow colostrum should be above 100,000 ts of 8~.For adapting the modern and social need, the push milk article industry development, research development the cow colostrum function food strategy, must understand the basic of the cow colostrum luck and process the characteristic.At often the cow colostrum of the milk different from milk is pure in also imply a cent of the cow colostrum function, contribute to developping these latent functions food resources milk period for raw material, measurese the different milk period, different PH value and increase the sour salt, cane sugar, calcium ion, EDTA, card of phosphoric acid salt, lemon to pull the gum, etc. allows hot concretion time( HCT) of increase the material in the food to the colostrum influence of the hot stability.
