    In daily life, many people often have to wait for the oil in the pot to smoke before putting the dishes when cooking, but doing so has health risks
    Professor Wang Yishan of the Health Management Center of the 107th Hospital of the People's Liberation Army explained that when the oil pan smokes, the temperature of the oil is often above 200°C.
    At this time, many nutrients in the vegetables are destroyed and some carcinogens are easily produced

    In addition, under high temperature, the fat-soluble vitamins and essential fatty acids contained in the oil are also destroyed, reducing the nutritional value of the oil


    How to control the oil temperature reasonably if you want to not only enjoy the delicious food, but also ensure that the nutrition of the food is not compromised? Fan Zhihong, an associate professor in the Department of Nutrition and Food Safety, College of Food Science and Technology, China Agricultural University, introduced an "onion skin test method": throw the onion skin into an oil pan.
    After the onion skin comes in contact with hot oil, it will foam.
    The oil can be judged by the oil bubbles.

    If there are few oil bubbles around the onion skin, it means that the oil temperature is not enough; if the onion skin turns yellow quickly, the temperature of the oil may be too high; it is best to see that the color of the onion skin has not changed, and at the same time it is still rising.
    With small oil bubbles, this is the right temperature


    Sun Guiju, director of the Department of Nutrition and Food Hygiene, School of Public Health, Southeast University, suggested that it is best to rotate various oils in daily cooking
    For example, soybean oil, sunflower oil, peanut oil, etc.
    can be used for stir-frying or stewing.
    Sesame oil, olive oil, linseed oil, etc.
    can be used for cold dressing.
    Coconut oil and palm oil should be used for fried foods.
