At least 3 bottles of oil should be placed in the kitchen! Don’t use 1 can of oil to connect, and the nutritionist will point to purchase oil products 5 principles. Remember to choose a small glass bo

The most taboo thing about food and cooking is to connect a can of oil. It is recommended that the public prepare 3 cans of oil for cooking according to three cooking methods, including high-temperature frying, low-temperature stir-frying and mixing; do not eat products produced by the same manufacturer or the same type of oil for a long time.

5 principles for purchasing oil products

1. Choose small packages for glass bottles: Zhang Silan, a nutritionist at Guotai Hospital, said that glass bottles are the best, but in the market, the plastic bottles are used in the market, so they have to settle for the second best. Don’t buy them in large quantities because of the cheap price to ensure the freshness of the oil products.

2. Pay attention to the proportion and ingredient marking: Each product contains the main and secondary components, etc. Usually, the more the ingredients are arranged in the previous one, the more the content it accounts for. In the mixed oil products, you can also see which oil accounts for the most proportion.

3. 3. 3 types of oil should be purchased: the focus is on the "smoking points" of various oil products. The temperature of the thinning smoke just occurs when the oil is heated is called the smoke point, and the oil begins to deteriorate when the oil is heated to the smoke point.

. High temperature decoction and frying ingredients: use grape seed oil with smoke above 200℃.

. Low-oil temperature and medium-fired stir-fry: You can use sesame oil, soybean oil or peanut oil.

. Mixed side dishes: sunflower oil and olive oil with the lowest smoke point, about 170℃.

4. Do not use the same product for a long time: Do not eat products produced by the same manufacturer or the same type of oil for a long time. In simple terms, it means using sunflower oil, canola oil, olive oil, peanut oil and other types of oils incorrectly. For example, this month is treated with sunflower oil, and the next month it is purchased for peanut oil. It is considered a concept of dispersing risks.

5. Open it and say: Do not open it and use it when you buy it. Use your nose to smell the smell. If it is opened, it will cause oil-consuming or smelly oily smell. Do not use it.
