酶联免疫吸附法和DNA检测法在肉类鉴别中的应用

Application of ELISA and DNA detection methods in meat identification

肉类食品是我国人民食品消费的主要组成部分,企业和经营单位为了追逐利润,时有将价格便宜的肉品掺入或替代高价格的肉品中进行加工和销售。为保护消费者对食品消费的知情权和规范肉类市场的秩序,食品生产、流通等监管部门应对肉类识别技术进行系统的分析和研究,进而建立相应的规范识别方法。目前用于肉类掺假鉴别的方法有组织学、化学、免疫学和基于DNA序列的检测方法等。本文主要针对ELISA检测方法和DNA检测方法在肉类识别中的应用进行阐述分析,并对我国肉类识别标准方法的缺陷进行分析。

Meat is the main component of food consumption. In order to make profit,companies may adulterate cheap meat to expensive meat during processing and marketing. To protect the consumer’s right and regulate meat market,supervision agencies should systematically analyze meat identification technology and establish an appropriate methods.Currently,the methods of meat identification include histological methods,chemical methods,immunological methods and DNA sequence-based detection methods. This paper focuses on the application of ELISA and DNA detection methods in meat identification. Besides,the defects of GB standards were also analyzed.
