Peanut oil can last for about a year and a half unopened. The shelf life of peanut oil sold on the market is generally 18 months. If it is placed in a cool, dry place and is not opened, it can be stored for 18 months. If it has been opened, do not store it for too long. It is recommended to eat it as soon as possible.

Peanut oil can last for several years if unopened.

Opened peanut oil will undergo oxidative rancidity during storage. If left for a long time, it will deteriorate and have a peculiar smell.

It is not recommended to consume peanut oil that has passed its shelf life. Expired peanut oil may breed aflatoxin, and consumption may easily cause physical discomfort.

Good peanut oil is light yellow in color, transparent, clear in color, fragrant in smell and delicious in taste.
