食用油过氧化值快速检测试剂盒的研制及其性能评价
目的研制一种新型的食用油中过氧化值快速检测的试剂盒。方法探索合适的替代溶剂以及最佳的试剂配比;依据GB 5009.37-2003原理制作标准比色卡,在反应载体上进行显色反应,通过目视比色快速判定待测油脂的过氧化值。在食用油常温存放的3个月内,同时采用试剂盒方法和国标方法检测其过氧化值,通过比较验证试剂盒的准确性和稳定性。结果选择安全低毒的乙醇：异辛烷（70：30,V：V）作为试剂盒实验的混合溶剂,在配置的简单载体上可快速进行显色反应,可检测的过氧化值区间范围为0.5-20 meq/kg。试剂盒在常温下存放的3个月内都能保持较好的准确度和稳定性。结论该试剂盒可用于食用油中过氧化值的快速筛查,具有...
