交流阻抗技术在牛奶质量安全检测中的应用

The Application of AC Impedance Technology in the Detection of Milk Quality and Safety

牛奶的质量和安全是食品安全的重要组成部分,关系到老百姓的身体健康和生命安全。保障牛奶质量能确保消费者从牛奶中获得足够的期望营养物质,而保障牛奶安全能避免对消费者造成危害。交流阻抗技术是一种具有潜力的检测方法,最早应用在电化学检测,在食品检测方面应用时间较短。国内外学者针对交流阻抗技术在牛奶质量安全方面的检测做了一些研究,发现其是一种快速、有效的检测方法。本文对交流阻抗技术应用在牛奶乳脂含量、含水量、酸败和货架期等质量方面的检测以及体细胞数、抗生素残留、细菌总数和掺假等安全方面的检测进行了综述,以供我国相关方面的研究学者、产品开发者和奶牛养殖者借鉴和参考。

Milk quality and safety is an important part of food safety, which relates to people＇s health and life safety. Guaranteeing milk quality could ensure consumers get enough nutrients expected from milk whereas milk safety for avoiding damages. AC impedance technology is a kind of potential detection measurement which was earliest applied in electrochemical detection however, it has been short time using in food detection field. Based on AC impedance technology, domestic and foreign scholars do some research which shows it is a fast and effective detection method. This paper reviews the application of AC impedance technology in the detection of milk quality （milk fat content, moisture content, rancidity and shelf life） and milk safety （somatic cell count, the total number of bacteria, antibiotic residues and adulteration） to provide certain references for our related research scholars, product developers and dairy farmers.
