When cooking fried food, you must choose oil with high temperature resistance (high smoke point) to prevent the oil from changing at high temperature and producing carcinogens that are harmful to your health.
The field experiment showed that the smoking point of soybean oil, olive oil, peanut oil, sunflower oil and rapeseed oil was peanut oil > soybean oil > rapeseed oil > sunflower oil > olive oil. Therefore, fried food is more suitable for peanut oil, but it should also be eaten less.
2, cooking: rapeseed oil.
Stir-frying is a widely used cooking method in life. When choosing edible oil, we mainly look at the fatty acid composition inside.
Fatty acids in oils and fats include saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids. Among them, saturated fatty acids are independent attack factors of cardiovascular diseases, while polyunsaturated fatty acids and monounsaturated fatty acids are beneficial to human health, and the content of monounsaturated fatty acids is better.
Relatively speaking, rapeseed oil has higher monounsaturated fatty acids and lower saturated fatty acids, so it is a good choice for cooking.
