Why are there bugs in vinegar?

The vinegar produced by regular enterprises has been sterilized before packaging, and generally it will not be infected in a sealed state. However, the vinegar in this seasoning bottle can also produce insects because it comes into contact with air or mixes with some eggs and foreign objects. Acetic acid is not high, and there are nutrients, which may lead to worms.

Many people basically buy a bottle of vinegar after eating it. There are few barrels or bottles of old vinegar that have not been eaten for a long time and have not been left. Some people think that it will expire after a long time. In fact, the old man said that it will not expire, and there will be a miracle when the old vinegar is left for a long time, that is, the vinegar moth!

Extended data:

The vinegar moth is a sticky thing, and then it will be layered. It's really layered. Many people have never seen it. In fact, not all vinegar can produce vinegar moths, but it also needs temperature and environment. If it is higher than 55 degrees, it really takes 10 minutes to roast the vinegar moth to death.

The vinegar at home can really brew vinegar moths, which is really good vinegar, and if you brew vinegar directly in this way, you can save a lot of money and it is still very healthy. After all, I made it myself.
