Why is it easy to get worms when soy sauce is not covered?

Causes of worms in soy sauce: In hot weather, worms in soy sauce are not uncommon, but they all have one common feature, that is, almost all of them are caused by improper storage after use. This is because soy sauce is a liquid condiment fermented from soybean, wheat flour and other raw materials. Its rich black bean flavor and rich nutrients are easy to attract flies to lay eggs. In hot weather, the eggs of flies may develop into insects within 6-24 hours. When the bottle cap is opened for use again, maggots originally attached to the bottle cap will fall into the bottle. The temperature in summer is often above 30℃, which is not difficult to explain why some consumers buy soy sauce and grow bugs a day or two after opening it.

Why is soy sauce more susceptible to worms? Soy sauce can be divided into soy sauce and soy sauce. Soy sauce is used for coloring and soy sauce is used for refreshing. There is an umami index "amino acid nitrogen" in soy sauce. The higher the content, the higher the freshness of soy sauce. Generally speaking, the amino acid nitrogen content of soy sauce is higher than that of soy sauce, and the aroma of soy sauce is more delicious and rich, which is more likely to attract flies to bite.

Hygiene and safety of modern soy sauce brewing: the main raw material of soy sauce is soybean, and the production process generally goes through the steps of raw material screening, cooking, koji making, brewing drying, squeezing, sterilization, filling and so on. In the modern condiment industry, the scientific and technological progress of soy sauce production has advanced by leaps and bounds. China soy sauce industry has entered a new stage of intelligent manufacturing through technological transformation and innovation.

In the modern soy sauce industry, koji-making is carried out in a fully enclosed space. All koji-making and koji-drying are fermented in a closed koji-drying pool or fermentor, transported by food-grade pipelines and filled in an extremely clean and clean area. The filling cleanliness of some brand enterprises even reaches the cleanliness standard of pharmaceutical production level, and the high temperature sterilization and filtration exceeding 120 degrees make the probability of flies or eggs appearing in the production environment almost zero. Therefore, it is best to choose well-known brands to buy soy sauce products.

How to avoid soy sauce bugs The hotter the weather, the easier it is to breed bacteria and produce flies. The higher the temperature, the shorter the incubation time of fly eggs. Soy sauce is rich in amino acids. Generally, when cooking, consumers will get water on their hands. Open the soy sauce bottle cap with hands covered with water. Adding amino acids to water is equivalent to cooking a delicious meal for flies. Coupled with the continuous high temperature in summer, often above 30℃, the probability of insect birth will increase.

But the environment of modern families has been greatly improved, there are fewer flies, and the probability of encountering bugs in soy sauce is very low. So, there is no need to panic. The following aspects can be basically prevented: 1. Domestic garbage is packed in plastic bags. Don't stay in one place for a long time, and don't let flies come into contact with it to lay eggs. 2. Try to keep the kitchen dry, and eliminate the garbage and sanitary corners in front of and behind the house and inside and outside the unit in time. 3, soy sauce should not be placed next to the gas stove to contact high temperature, otherwise it will easily deteriorate. 4. After using soy sauce, it is best to clean the bottle mouth with a rag, cover the bottle cap tightly and put it in a cool, ventilated and dry place. If possible, soy sauce can be stored in the refrigerator, especially in the case of continuous high temperature in summer. Please don't put it on the windowsill that can be exposed to the sun. Too long time or exposure will affect the quality of soy sauce.
