Hello, I can't eat. The shelf life of edible oil is generally 18 months, especially when the vat of edible oil is opened 1 month, so it is difficult to "keep fresh". Therefore, it is obviously inappropriate to hoard a large amount of edible oil. Therefore, we must pay attention to the shelf life of edible oil, and must not eat expired oil, turbid, precipitated or "spicy" edible oil.
