大型运动会运动员餐厅食品留样方法的研究

The Research of Food Sampling Method in Athlete Dining Room of Large-scale Athletic Meeting

通过实验室模拟运动员餐厅的操作规范生产30道菜肴,采用新构建的方法与传统的方法对其留样并对比检测。检测结果显示:传统方法食品留样期满后食品的大肠菌群检测合格率为75%,新方法食品留样期满后食品的大肠菌群检测合格率为93.3%;传统方法食品留样期满后食品的菌落总数检测合格率为73.3%,新方法食品留样期满后食品的菌落总数检测合格率为90%。总之,新食品留样方法能有效地提高留样食品期满后食品微生物检测的准确性。

30 dishes were cooked in lab by simulating operation standard of athlete dining room, and their samples were kept, detected and compared between new and traditional methods for keeping food sample. The results showed that the qualification rates of Escherichia coli and total bacterial count were 75%, 73.3% for traditional method and 93.3%, 90% for new method when keeping time expired. The new method of keeping food samples could effectively improve the accuracy of food microorganism.
