中文摘要:

      目的 为了更好地控制原料奶及成品的产品质量, 形成一种简便的检测方法, 更快更准确地鉴别掺假牛奶。方法 实验选用传统的国标方法、直接进样法、标准加入-直接进样法三种不同的试验方法对几种产品进行检测, 并比对各种方法的优劣, 从而得到较理想的方法。结果 各试验组的钙、钠检出限分别为0.42 mg/100 g和3.75 mg/100 g、0.38 mg/100 g和0.96 mg/100 g、0.38 mg/100 g和0.96 mg/100 g。结论 标准加入-直接进样法是一种新型的、快速且准确的检测方法。

英文摘要:

      Objective In order to control the quality of raw milk, a simple, fast and accurate identification of mixing milk detection method was established. Methods National standard method, direct sampling method and standard additions- direct sampling method were applied to testing for several products and comparing the pros and cons of various methods, finally, the experimental method was obtained. Results For each tested method group, the calcium and sodium detection limits were 0.42 mg/100 g and 3.75 mg/100 g, 0.38 mg/100 g and 0.96 mg/100 g, 0.38 mg/100 g and 0.96 mg/100 g, respectively. Conclusion The standard additions-direct detection method is a novel, rapid and accurate detection method.
