摘　　要：利用乳酸脱氢酶测定试剂盒测定巴氏杀菌乳、超高温灭菌乳和复原乳中乳酸脱氢酶活性的差异以鉴定复原乳。结果显示:巴氏杀菌乳中乳酸脱氢酶的活性显著高于超高温灭菌乳和复原乳。该方法操作简单、快速准确,值得推广。Lactate dehydrogenase exists widely in human and animal tissues and body fluids.Due to the temperature influence in different processing technologies,the activity of lactate dehydrogenase was different in pasteurized milk,ultra-high temperature-treated milk and reconstituted milk.A commercially available lactate dehydrogenase kit was used to determine the activity of lactate dehydrogenase in pasteurized milk,ultra-high temperature-treated milk and reconstituted milk for identifying reconstituted milk.Results indicated that the activity of lactate dehydrogenase of pasteurized milk was significantly higher than those of ultra-high temperature-treated milk and reconstituted milk.This method is of easy operation,rapidity and high accuracy and consequently,deserves to be popularized.
