One of the most commonly used condiments for cooking at home is soy sauce, especially during the Spring Festival. But you know what? Soy sauce has two uses: heating cooking and cold mixing (ordering, dipping, etc.), but many people don't pay much attention to the choice when buying. There is often only one at home.

You can't use ordinary soy sauce to mix cold dishes If you want to make cold dishes, you'd better choose a special cold soy sauce, which has stricter microbial indicators than cooking soy sauce. The national standard stipulates that the total number of colonies detected per milliliter of soy sauce used for cold meals shall not be greater than 30000. Even if it is eaten raw, it will not endanger human health. Experiments show that Shigella can survive in soy sauce for 2 days, paratyphoid bacillus, Salmonella and pathogenic Escherichia coli for 23 days and typhoid bacillus for 29 days.
