【摘要】 通过对3只泌乳山羊连续服用镉,研究了镉在山羊全乳及乳产品的分布。试验羊摄入镉之前,乳镉浓度为<0.2-0.2 μg/L,摄入镉期间,乳镉浓度为1.2～4.6 μgL,在奶油中镉的浓度是原始乳镉的3.1±0.7倍,在用酸化法和加酶法制作的奶酪中的镉分别是原始乳镉的3.3±0.3倍和5.7±0.7倍。原始乳中的镉,大约1/4(23.9±5.4%)分布在奶油中,大约60%分布在奶酪中(61.6±5.4%)分布在用加酶法制作的奶酪中,56.8±4.8%分布在用酸化法制作的奶酪中),分布在两种乳清中的镉分别为12.9±2.8%和16.3±5.3%。更多还原

【Abstract】 Distribution of cadmium in goat whole milk and its products was studied before and following a repeated oral cadmium administration to 3 goats.Prior to cadmium administration,milk cadmium levels ranged from less than 0.2 to 0.2μg/L.during cadmium administration,cadmium levels ranged from 1.2 to 4.6μg/L in the milk used for cheese making.The factor of concentration of cadmium from whole milk to cream was 3.1±0.7,to lactic curds was 3.3±0.3 and to rennet curds was 5.7±0.7.A quarter of the cadmium contained in the original milk was found in the cream(23.9±5.4%),about 60% in curd(61.6±5.4%) in rennet curds and 56.8±4.8% in lactic curds),12.9±2.8% in rennet curd whey and 16.3±5.3% in lactic curd whey.更多还原
