1. Pay attention to the storage environment; chili sauce is fermented, and the storage environment can have a great impact on its taste. A cool environment can have a beneficial impact on the storage of the sauce, and avoid sunlight. Pay attention to the location where the chili sauce is placed to avoid high temperature and humidity, which is beneficial to the storage of the chili sauce.

2. Pay attention to sealing; sealing is very important for the storage of chili sauce, which can protect the chili sauce from microbial attack and extend its edible period. Home-made chili sauce can be placed in a sealed jar. If there is no sealed jar, it can also be placed in a used canning bottle with a lid. If the canning jar does not have a lid, it can be sealed with a combination of rubber bands or ropes and plastic wrap.

3. Add more salt; salt is a natural preservative. You can use more salt to extend the storage period of home-made chili sauce, but be sure to pay attention to the amount. Do not add too much, which will cause the chili sauce to become stale. If it is difficult to enter, the gain outweighs the loss.
