摘要
以COΙ基因和16S r RNA基因作为鱼类制品通用的DNA条形码,对超市中采集的91份冷冻鱼肉样品及经过深加工的预包装鱼肉样品进行物种鉴定。结果表明:COΙ基因和16S r RNA基因均可用于鱼类制品物种真伪的鉴别;冷冻鱼肉样品和预包装鱼肉样品与其商标的符合率分别为83.54%和58.33%;市场中存在鱼类制品商品标签标示错误、配料标注不明确等问题,为相关部门对鱼类制品的监管提供了有力的技术支持。
This study was conducted to identify the species origin of 91 samples of frozen fish products and highly processed, pre-packaged fish products collected from supermarkets using DNA barcoding technique based on homologous sequence analysis of the CO1 and 16S rRNA genes. The results confirmed that both CO1 and 16S rRNA gene sequencing were useful for species authentication of fish products. The species origin of 66 of 79 （83.54%） frozen fish products and 7 of 12 （58.33%） highly processed, pre-packaged fish products was consistent with the product claims, which indicated that some problems such as mislabeling and ambiguous ingredient designation of fish products existed in the fish market. This research can provide technical support for the supervisory authorities concerned.
