摘  要:
通过检测不同酒精阳性乳血清和乳清中Ca2+、Mg2+、Na+、K+浓度及Cu、Zn、Fe、Mn含量,探讨其与酒精阳性乳的关系,结果显示,酒精阳性乳患牛体内的微量元素Zn、Cu和Fe代谢紊乱,会导致抗氧化酶的活性降低、毒性产物含量升高而使自由基代谢平衡紊乱,且Zn、Cu含量的缺乏会降低机体的免疫力;患牛乳中过多的Ca2+、Mg2+中和酪蛋白微胶粒表面的电荷,导致酪蛋白稳定性下降,致使乳胶体聚集能力增强;这些都易导致酒精阳性乳的形成。

摘  要:
To approach its influence to alcohol-positive milk,detecting the level of Ca2+,Mg2+,Na+,K+ and the content of Cu,Zn,Fe,Mn in blood serum and milk serum.The results indicated that Zn,Cu and Fe metabolic disorder,antioxidase active to cut down;redundant Ca2+and Mg2+neutralize the electric charge of casein to stability low down of casein,this made aggregation reinforce of reinforce,all of these can induce alcohol-positive milk.
