Like other foods, edible oil has a shelf life, and eating expired edible oil will do harm to human body. From the appearance, the high quality oil is moderate in color and soft in taste, which is made by careful selection and reasonable processing. On the contrary, the deep color of the oil does not mean that the oil is thick, but because of the low refining degree and many impurities. When choosing cooking oils, you should also pay attention to its production date and shelf life. Some bottle cooking oils do not have a shelf life, but this does not mean that cooking oils can be stored indefinitely. The experts warn that eating expired cooking oil will cause serious harm to the human body, especially the intestines and stomach.

Edible oil is stored for a long time, especially the crude oil, which contains more residues, it can cause rancidity of oil and fat. Edible oil contains a linoleic acid component that easily reacts with oxygen in the air. This phenomenon is called "oxidation of fats and oils". A series of reactions, such as oil and fat, hydrolysis, can produce small molecular aldehydes, ketones and carboxylic acids and other oxides, peroxides and other decomposition products with special odor. Rancidity is the result of oxidation and rancidity of oils. After the oil is rancid, it is smoked and smashed when heated, and contains the decomposition product, such as propylene glycol aldehyde, which is easily poisoned after consumption.

Therefore, we must pay attention to the shelf life, for the expired oil or turbid, precipitated edible oil, they cannot be eaten directly.
