Peanut oil produced by pressing has a strong aroma, among which vitamin E and carotene are preserved more. The zinc content is many times that of salad oil, rapeseed oil and soybean oil, so edible peanut oil is especially suitable for people to supplement zinc.
Edible suggestion: Suitable for general cooking, such as baking, long cooking and stir-frying. Try to avoid high-temperature frying.
Note: Peanut oil is divided into pressed products and solvent extracted products. The former is more fragrant. When buying, it is best to choose products with big brands and high grades. This is because peanuts are easily contaminated by aflatoxin, which is easily soluble in oil. Inferior peanut oil has this risk.
2. Sunflower seed oil-unsaturated fatty acid is the highest.
Sunflower seed oil is rich in linoleic acid, which is an essential fatty acid for our human body and is converted into arachidonic acid through complex processing. It is an essential component of prostaglandin that regulates physiological functions and promotes growth and development. Sunflower seed oil is suitable for all kinds of cooking methods without adding antioxidants.
3, soybean oil-stew is more suitable than boiling.
The fatty acid composition of soybean oil is linoleic acid 5 1.7%, oleic acid 22.4%, linolenic acid 6.7% and palmitic acid1.1%. Because soybean oil is rich in linoleic acid, it belongs to high linoleic acid vegetable oil and is rich in vitamin E.
Note: The concentration and composition of lampblack produced by four common edible oils (rapeseed oil, soybean oil, corn oil and peanut oil) were studied by experiments. The order of the concentration of oil fume is: soybean oil >; Corn oil > rapeseed oil > peanut oil
The results show that under the same cooking conditions, the concentration of oil fume, the types and total concentration of harmful substances produced by soybean oil are obviously higher than those of the other three edible oils, so it is suggested that families should avoid choosing soybean oil when cooking at high temperature.
4, corn oil-rich in vitamin E.
The advantage of corn oil is that the content of vitamin E is higher than that of ordinary vegetable oil, and it also contains a certain amount of antioxidant substances, which is beneficial to the skin and anti-aging.
Edible suggestion: It can be used for stir-frying and cold salad.
5, rapeseed oil-can be cooked daily.
Rapeseed oil is what we commonly call vegetable oil, also called coriander oil. Rapeseed oil contains little cholesterol and generally contains some seed phospholipids, which is very important for the development of blood vessels, nerves and brain. The absorption rate of rapeseed oil is as high as 99%, which can regulate blood pressure, blood sugar and blood lipid and enhance immunity.
Precautions:
1. Some rapeseed oils have high erucic acid content, which affects their nutritional value. So heat the wok, pour in rapeseed oil and cook for a long time to let some erucic acid evaporate.
2. Rapeseed oil should be eaten as soon as possible after opening the bottle. If it is left for too long, the polyunsaturated fatty acids in it are easily oxidized and destroyed by oxygen in the air, resulting in substances that are unfavorable to the human body.
Fortunately, rapeseed oil is also rich in vitamin E, which can enhance the antioxidant effect and protect a variety of unsaturated fatty acids from oxidative deterioration. However, it is recommended to buy a small bottle as much as possible and finish it as soon as possible.
