How to prevent cooking oil from going bad

Cooking oil is an essential condiment for every household, but the shelf life of cooking oil is only 18 months, and that is when it is sealed. Cooking oil that has been opened in the family often goes bad. What should we do at this time? How should we prevent cooking oil from going bad?

1. Use containers to prevent cooking oil from going bad

If you want to prevent cooking oil from spoiling, the container for storing cooking oil is very heavy. It is best to choose a ceramic jar and reduce the diameter of the jar. If there is less cooking oil at home, you can store it in an opaque glass bottle. After filling it, seal the bottle mouth to reduce contact with air, so as to prevent the cooking oil from spoiling.

2. Change the environment to prevent edible oil from deteriorating

The choice of environment when storing cooking oil is also very important. Containers containing cooking oil should be placed in a dark, dry and low temperature place. They should not be exposed to sunlight. Otherwise, the ultraviolet and infrared rays in the sunlight can promote the oxidation of oil and accelerate the formation of harmful substances, causing the cooking oil to deteriorate.

3. Adjust the temperature to prevent the cooking oil from deteriorating

If you want to prevent cooking oil from spoiling, the ambient temperature is also very important. It is suitable to be stored in a low temperature environment. The normal storage environment should be between 10 and 15 degrees, and the highest should not exceed 25 degrees. That is to say, you cannot buy too much cooking oil at home in summer, otherwise it will easily spoil. In addition, when storing cooking oil, you can also add a variety of antioxidants such as pepper, fennel and cinnamon to extend the shelf life of cooking oil and prevent it from spoiling.
