试剂盒法检测低乳糖牛奶中乳糖质量分数的方法

Adulteration of raw milk in the qualitative determination of zinc salts

为了提高检验速度,降低检验成本,特对现有乳糖试剂盒法进行开发,以满足生产、检验的需求。低乳糖牛奶由于乳糖质量分数比较低,用现有的国标滴定法无法进行检测[1],而色谱法需配备液相色谱仪,成本较高,且检测速度比较慢,试验对原有乳糖检测试剂盒进行研究改进,在其基础上针对个别细节进行了修订,使原有方法更细化,从而快速检测低乳糖牛乳中乳糖质量分数[2]。本研究检出限为3g/kg。结果表明,该方法灵敏度高,操作简单,成本低廉,结果准确,能够满足在线生产及研发需求[3]。

In order to improve the speed test,Reduce inspection costs ,Special kit to existing law to develop lactose ,To meet production, Needs test. Lactose content of low lactose milk is relatively low because ,With the existing national standard titration method can not be detected, The chromatography to be equipped with liquid chromatography, High cost, And the detection of more slowly, Test the original study of lactose improved detection kit, Based on their individual details of the revised, So that the original method is more refined, To rapid detection of low-lactose milk lactose content. The detection limit was 3 g/kgo The results show that, The method is sensitive, ease of clinical,low system cost, system accuracy, To meet the needs of online production and R ＆amp; D.
