关于月饼的苯甲酸检测没有明确的处理和检测方法,按照国标GB/T5009.29-2008的要求第一法气相色谱法和第二法液相色谱法进行检测。气相色谱法前处理涉及有机溶剂的重复萃取,操作时间较长,比较麻烦,液相色谱法也没有明确月饼的前处理方法。本文结合液相色谱法中的试样处理中的方法,对月饼的检测,采用了样品粉碎均匀称样后90度水浴30分钟的方法,加蛋白质沉淀剂定容过滤后直接进样,缩短了检测的时间,提高了工作的效率,适合大批量处理样品。 On the moon cake benzoic acid test no clear handling and testing methods, in accordance with the national standard GB / T5009.29-2008 requirements of the first method of gas chromatography and the second method of liquid chromatography for testing. Gas chromatography pretreatment involving repeated extraction of organic solvents, the operation time is longer, more troublesome, there is no liquid chromatography clear moon cake pretreatment methods. In this paper, liquid chromatography method in the sample treatment, the detection of moon cake, using a sample crushed uniform 90 ° water bath for 30 minutes after the method, plus protein precipitating agent volumetric filtration directly after injection, shortened Testing time, improve the efficiency of work, suitable for high-volume processing of samples.
