If there are old people and children at home, you should first choose peanut oil and rapeseed oil with good heat resistance when cooking. However, when cooking with this oil, vegetables should be put into the pot before the oil fume is obviously produced, so as to avoid putting vegetables when the oil fume is too large. Although sunflower oil, soybean oil and corn oil also contain a lot of unsaturated fatty acids which are very helpful to human health, their heat resistance will be poor. If these oils are used for cooking, the oil temperature must be strictly controlled.
When chopsticks are put into oil to produce bubbles, put the vegetables in, and avoid cooking them for too long. In fact, sunflower seed oil, soybean oil and corn oil are more suitable for short-term wok, suitable for stews, fried eggs, steamed vegetables, soup and various non-fried noodles. Blended oil is a mixture of various oils, so its smoke point will be difficult to determine and it is not suitable for frying.
