本文聚焦乳制品生产企业,深入钻研季铵盐消毒与浓度检测。在乳制品生产中,设备清洁消毒是食品安全的关键防线,季铵盐消毒剂优势突出,被广泛用于食品设备消毒,但规范使用和精准检测至关重要。乳制品生产企业需严格依照法规标准,对生产设备、环境和工器具等环节严格消毒并做好个人防护。当前季铵盐浓度检测方法多样,现场快速检测的试纸条和试剂盒操作简便,能快速出结果,不过精度欠佳,实验室的高效液相色谱 - 串联质谱法,灵敏度和选择性高,但设备昂贵操作复杂,对人员专业要求高。本实验室开发的滴定方法,经精密度和准确度实验验证,操作简单,成本低且精确度高,适用于苯扎氯铵消毒剂中季铵盐含量的检测。乳制品生产企业应结合自身实际,合理选用检测方法,切实提升乳制品生产的质量与安全性,为消费者提供放心产品。

This paper focused on dairy production enterprises,delving deep into the study of quaternary ammonium salt disinfection and concentration detection. In dairy production,the cleaning and disinfection of equipment constitute a crucial line of defense for food safety.Quaternary ammonium salt disinfectants,boasting prominent advantages,are extensively utilized in the disinfection of food equipment.However,standardized application and precise detection are of paramount importance.Dairy production enterprises must strictly adhere to relevant regulations and standards,rigorously disinfect production equipment,the production environment,tools,and other aspects,and ensure proper personal protection.Currently,there is a wide variety of methods for detecting the concentration of quaternary ammonium salts.On - site rapid - detection test strips and kits are easy to operate and can yield results swiftly,yet their accuracy leaves something to be desired.The high - performance liquid chromatography - tandem mass spectrometry （HPLC - MS/MS） method in the laboratory features high sensitivity and selectivity.Nevertheless,the equipment is costly,the operation is intricate,and it demands personnel with high - level professional expertise.The titration method developed by our laboratory has been validated through precision and accuracy experiments.It is simple to operate,low in cost,and highly accurate,making it suitable for detecting the quaternary ammonium salt content in benzalkonium chloride disinfectants.Dairy production enterprises should make a rational choice of detection methods in light of their actual circumstances,thereby effectively enhancing the quality and safety of dairy production and providing consumers with reliable products.
