Can expired cooking oil still be used?

In life, some friends may be always busy with work, and when they have a break, they just stay at home and rest. So I don’t go shopping for oil, salt, sauce and vinegar very often, but at this time I usually buy a lot each time. Among them, cooking oil is an ingredient that everyone buys for a long time, because it is needed whether it is for cooking or making soup. But there are still some friends who buy too much and the oil is expired. At this time, everyone wants to ask, can the cooking oil still be used after it expires?

Experts remind that cooking oil, like other foods, has a shelf life, and consuming expired cooking oil can be harmful to the human body. From the appearance, high-quality oil has moderate color and light and soft taste, which is made through careful selection of materials and reasonable processing. On the contrary, the dark color of oil does not mean that the oil is concentrated, but rather it is due to the low degree of refining and the presence of impurities. When purchasing oils and fats, you should also pay attention to their production date and shelf life. Some bottled cooking oils do not have a shelf life indicated, but this does not mean that the cooking oil can be stored indefinitely. Doctors warn that consuming expired cooking oil can cause serious harm to the human body, especially the stomach and intestines.

Common misunderstandings about cooking oil

1. Cooking at high temperature

Many people like to stir-fry at high temperature and are accustomed to waiting until the oil in the pan smokes before cooking. This practice is unscientific. High-temperature oil not only destroys the nutritional components of food, but also produces some peroxides and carcinogens. It is recommended to heat the pan first, then pour the oil. You can then stir-fry the vegetables without waiting for the oil to smoke.

2. Do not eat vegetable cooking oil or animal oil

Without oil, the body will suffer from vitamin and essential fatty acid deficiency, which will affect human health. It is not a good idea to simply emphasize eating only vegetable oil and not animal oil. At certain doses, animal oils (saturated fatty acids) are beneficial to the human body.

3. Eating only a single type of oil for a long time

It is still difficult for ordinary families to decide which oil to use for cooking different dishes, but we recommend that it is better to use several oils alternately, or use one oil for a period of time and switch to another oil the next period of time, because there is rarely one oil that can solve all oil needs.

4. For people with abnormal blood lipids or abnormal weight, there is no difference in using oil.

For people with abnormal blood lipids or special groups with abnormal weight, we emphasize more on choosing high monounsaturated fatty acids in vegetable oils. The amount of oil used should also be controlled. The total oil consumption of people with normal blood lipids and weight should be controlled at no more than 25 grams per day, with polyunsaturated fatty acids and monounsaturated fatty acids basically accounting for half each. For the elderly, people with dyslipidemia, obese people, people with obesity-related diseases or people with a family history of obesity, the amount of oil consumed per person per day should be even lower, even reduced to 20 grams.

The above content is a detailed introduction by the editor on the question of whether edible oil can be used after it expires. I hope everyone knows that edible oil cannot be used after it expires because it is not good for the body. Therefore, you must prepare cooking oil in moderation when preparing it. If you prepare too much, it will expire and be wasted.
