Generally speaking, soy sauce can be eaten without heating. However, in the process of production, storage, transportation and sales, soy sauce is often contaminated due to poor sanitary conditions, and may even be mixed with a variety of pathogenic bacteria. If people eat raw soy sauce, it will be harmful to their health. In addition, soy sauce will produce more ammonia nitrogen during fermentation. The more ammonia nitrogen, the heavier the burden on the liver, which will aggravate the condition of liver disease. Furthermore, raw soy sauce contains halophilic bacteria, which can survive in salty foods with high solubility, so it can also survive in soy sauce for a long time. Halophilic bacteria can cause nausea, vomiting, abdominal pain, diarrhea and other symptoms after entering the human body. Therefore, the soy sauce should be cooked thoroughly before eating. ?
