Can peanut oil still be eaten after it expires? expired
Edible oil is also known as "edible oil", which refers to animal or vegetable oil used in the process of making food. It is liquid at room temperature. Due to the source of raw materials, processing technology and quality, most common edible oils are vegetable oils, including corn oil, peanut oil, olive oil, camellia oil, canola oil, sunflower oil, soybean oil, sesame oil, walnut oil and so on.
Can I still eat cooking oil after it has expired?
Experts warn that edible oils, like other foods, also have a shelf life, and eating expired edible oils can be harmful to the human body. From the outside, high-quality oils have a moderate color and a light and soft taste, which is made through careful selection of materials and rational processing. On the contrary, the dark color of oils does not mean that the oil is thick, but because of the low degree of refining and many impurities. When purchasing oils, you should also pay attention to their production date and shelf life. Some bottled edible oils do not have a shelf life marked, but this does not mean that edible oils can be stored indefinitely. Doctors warn that eating expired edible oils can cause serious harm to the human body, especially the stomach.
Common misconceptions about cooking oil
1. High temperature cooking
Many people like to use high temperature stir fry when cooking, and they are used to waiting until the oil in the pot is smoking before cooking. This practice is unscientific. High temperature oil will not only destroy the nutrients of the food, but also produce some peroxides and carcinogens. It is recommended to heat the pot first, and then pour the oil, then you can cook vegetables without waiting for the oil to smoke.
2. Do not eat plant-based cooking oils, or do not eat animal oils
If there is no oil, it will cause a lack of vitamins in the body and a lack of essential fatty acids, which will affect the health of the human body. It is not possible to blindly emphasize eating only vegetable oils and not animal oils. At a certain dose, animal oils (saturated fatty acids) are beneficial to the human body.
3. Eat only a single variety of oil for a long time
It is still difficult for the average family to cook what vegetables and what oil to use, but we recommend that it is best to eat several oils alternately, or use one oil for a period of time and another oil for the next period of time, because few oils can solve the problem of all oil needs.
4. People with abnormal blood lipids or people with abnormal weight use oil no differently
For people with abnormal blood lipids or special people with abnormal weight, we place more emphasis 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, and polyunsaturated fatty acids and monounsaturated fatty acids should basically account for half. And the elderly, people with abnormal blood lipids, obese people, people with obesity-related diseases or people with a family history of obesity, their daily oil consumption should be lower, even down to 20 grams.
