中文摘要:

      目的 了解呼和浩特市乳制品中三聚氰胺残留情况。方法 从超市采集69份奶粉制备的休闲乳制品及奶酪和奶皮等传统乳制品, 另外采集4个品牌128份液态奶。采用高效薄层色谱法和免疫胶体金检测卡进行三聚氰胺残留检验。结果 197份样品中除了7份奶粉制备的休闲乳制品和2个工厂制作奶酪免疫胶体金法检验结果可疑外, 其他样品检验结果均为阴性。结论 高效薄层色谱法虽不如免疫胶体金法灵敏, 但检测成本较低, 适合进行日常大规模筛查性检验。

Methods A total of 69 milk powder of leisure dairy food and Mongolian conventional cheese and “milk-skin” samples, as well 128 liquid milk samples of 4 brands were collected from supermarkets of Hohhot city. Melamine residue was test by a high performance thin layer chromatography (HPTLC) method and an immune colloidal gold test kit (ICGT). Results Except 7 milk powder made leisure foods and 2 dairy factory made cheese samples were suspicious (±), the remaining of 197 dairy samples were melamine free (?). Conclusion The HPTLC methods was not as sensitive as the ICGT, however, it is a cheaper method for daily melamine residues screening.
