Edible oil is an ingredient we will definitely use when cooking. It not only makes food more delicious, but also contains various vitamins, which can supplement our body with nutrition.
However, there are also some special considerations when using cooking oil. For example, the following cooking oils are best eaten less, or even not.
1. Repeated heating oil
Sometimes we use more oil when we fry something at home, and after we make the fried food, a lot of oil will remain. Some people think it is a waste to throw it away directly, and they will keep the oil and use it for cooking next time.
However, when we fry the thing, the oil has been heated repeatedly. During the heating process, the nutrients of the oil have been almost lost. At the same time, harmful substances such as trans fatty acid , benzopyrene will also be produced.
. We all know that trans fatty acids are difficult to digest by our body and may increase the risk of cardiovascular and cerebrovascular diseases . Benzopyrene is a carcinogen . Eating too much is harmful to our body.
2. Oil that has been opened for more than 3 months
Many people believe that as long as it is still within the shelf life, cooking oil can still be eaten, but as long as it is opened for more than 3 months, it is best not to eat it regardless of whether it expires or not.
Because after edible oil is opened, it is easily contaminated by bacteria. If the sealing treatment is not done well, the oil and fat often come into contact with the air, which will oxidize and produce oxidation products.
If we eat too much cooking oil containing oxidized products, we will easily experience vomiting, diarrhea, etc., and in severe cases, even life-threatening.
Therefore, it is best for us to buy small bottles of cooking oil and use up the Kaifeng cooking oil as soon as possible.
3. Small workshop self-pressing oil
When we go to the vegetable market to buy ingredients, we will find that there are some shops that specialize in selling self-pressing oil. These self-pressing oils have a strong fragrance, which makes people want to buy some and go home.
Many people also believe that self-pressed oil will have a more mellow taste, and it will make the dish more fragrant when used for stir-frying, but these self-pressed oils are not safe.
Because we do not know whether the machine used for self-pressing oil is disinfected and whether the raw materials used are qualified.
and are generally not refined, and contain more impurities and harmful substances , and may even contain aflatoxin . This toxin is very harmful to our body. Therefore, we are best able to buy cooking oil made by regular manufacturers. Which oil is better for
