What is the shelf life of peanut oil? What should be paid attention to during the shelf life of peanut oil?

Peanut oil is the most commonly consumed edible oil in people's lives. It is extracted from peanuts and has a strong peanut aroma. It also contains a variety of nutrients that are beneficial to the human body. However, like other oils, it also has a shelf life. After the shelf life is exceeded, it will also go bad. After deterioration, it can no longer be eaten. So how long is the shelf life of peanut oil? What should we pay attention to during the shelf life of peanut oil?

1. What is the shelf life of peanut oil?

Most of the barreled peanut oil that people buy will have a shelf life label on the outer packaging. The normal shelf life of peanut oil should be about eighteen months, or one and a half years. However, this shelf life refers to the peanut oil being sealed in the barrel and under suitable temperature conditions. If it is bulk peanut oil, its shelf life will be even shorter as they are prone to oxidation and deterioration.

2. Storage temperature of peanuts

The external temperature is very important when storing peanut oil. It is best to store it in an environment above 15 degrees, and the container where the peanut oil is stored must be sealed. Otherwise, the lipase in the peanut oil will oxidize, causing the acid value of the peanut oil to be too high, which will cause the peanut oil to deteriorate.

3. Acidic substances can be added when peanut oil is stored

If you want to preserve peanut oil for a long time, you can add 2% citric acid or ascorbic acid to the peanut oil at the beginning of storage. This will reduce the activity of metal substances in the peanut oil and inhibit the occurrence of oxidation reactions, thereby extending the shelf life of the peanut oil. Most of the barrels of peanut oil that people buy contain these acidic components.
