Abstract
Considering that the authentication of food contents is one of the most important issues for the food quality sector, and given the increasing demand for transparency in the meat industry followed the horsemeat scandal in Europe, this study investigates processed-meat products from Italian markets and supermarkets using the mitochondrial cytochrome b gene qualitative PCR identification system in order to verify any species substitution or mislabeling. The results revealed a high substitution rate among the meat products, highlighting a mislabeling rate of 57 %, and consequently, considerable discordance with the indications on the labels, which raises significant food-safety and consumer-protection concerns.
摘要
鉴于食品成分的鉴定是食品质量领域最重要的问题之一，并且鉴于欧洲马肉丑闻后肉类行业对透明度的需求不断增加，本研究使用线粒体细胞色素b基因定性PCR鉴定系统对意大利市场和超市的加工肉类产品进行调查，以核实是否存在任何物种替代或标签错误的情况。结果显示，肉类产品中的替代率很高，突出显示标签错误率为57%，因此，与标签上的说明存在相当大的不一致，这引发了重大的食品安全和消费者保护问题。
