You Have These Habits When Cooking, So I Suggest You Quit!

If you do not pay attention to these details in cooking, it is extremely detrimental to our health. Do you have these habits?

Mistake 1: Cut vegetables before washing

In order to save trouble, many people like to cut all the vegetables first, and then pour them into the basin for washing, but the consequences of doing so may lead to the loss of nutrients.

Some vitamins and minerals in vegetables are easily soluble in water. For example, B vitamins and vitamin C belong to this category. Large-area contact with water will only cause the loss of these water-soluble vitamins. Similarly, it is not advisable to cut vegetables too finely for soaking.

In addition, it is not good to cut and prepare the vegetables early, and then fry them until they are ready to be eaten, because the vitamins in the vegetables will be oxidized and destroyed if they are left for too long.

The correct method: Before cooking vegetables, you can wash the vegetables first, control the moisture as much as possible, and then cut them. The washed vegetables should be cooked as soon as possible, and it is recommended that they should not be placed for more than 2 hours.

Mistake 2: Cut raw and cooked food with a kitchen knife

The kitchen at home is small, so many people may only prepare a cutting board and a kitchen knife in order not to take up space, and use them to cut raw and cooked food. However, everyone should also know that there are a lot of bacteria and parasites in raw food such as livestock and poultry meat and aquatic products. These bacteria and parasites will inevitably remain on kitchen knives and cutting boards when processing and cutting.

If you use these "contaminated" kitchen knives and cutting boards to deal with cooked food, it is tantamount to "contaminating" cooked food. Even if you "scal" it with boiling water before use, it will not completely eliminate bacteria and parasites, and of course it will not have any disinfection effect.

Correct way: Whether it is a cutting board or a kitchen knife, the editor recommends that you prepare two servings to completely separate raw and cooked foods. The cutting board and kitchen knife should be cleaned, especially the cutting board, and must be scrubbed clean after use. But don't scald them with hot water, so as to prevent the protein in the meat from remaining on the cutting board, it will solidify when heated, and it is not easy to clean.

Mistake 3: Boil the dish without boiling water

For some vegetables with a high oxalic acid content (such as spinach, amaranth, rice white, bamboo shoots, etc.) or vegetables that are intended to be eaten coldly, blanching is an indispensable process. But at this step, most people are easy to make mistakes.

Because they are afraid that the water temperature is too high to damage the nutrients in the vegetables, some people put the vegetables down before the water boils. In fact, the most serious temperature of chlorophyll loss is not 100°C, but 60-82.2°C, because at this temperature The most suitable chlorophyll enzyme to play (ie destroy chlorophyll). In addition, the blanching time is too long, which will only cause more nutrients in the vegetables to be lost.

Correct method: When blanching vegetables, it is recommended to add as much water as possible, adjust the firepower to the maximum, and shorten the blanching time; and the blanching time should not be too long, generally 5~10 seconds; add a few drops of cooking oil before removing it. A protective film is formed on the surface of vegetable leaves to slow down the oxidation rate of vegetables.

Mistake 4: Dishes are served only when the frying pan is smoking

This is probably a peculiar habit of Chinese cooking. Sometimes in order to increase the aroma of the dishes, they will first "cook the pot", and put the onion, ginger, garlic and other condiments into the smoky oil pot to "cook" the fragrance before cooking.

When the oil is heated to 150°C, the edible oil will already produce "acrolein" which has a strong stimulating effect, which damages the mucous membranes of the nose, eyes and throat. When the oil pan smokes, the temperature of the oil often reaches above 200°C, and the oil smoke produced at this time is very toxic. Long-term exposure to such high-temperature oil fume will increase the risk of lung cancer.

Correct method: It is recommended to serve the dishes before the pan smokes. Generally, insert a bamboo chopstick into the pan. When there are small bubbles around it, it means that the temperature is almost the same.

Mistake 5: Put the salt too early

Adding salt when cooking is a question of the university, too much, too little, not too early, too.

Adding salt to the fried vegetables too early will cause too much juice to flow out of the vegetables, causing loss of nutrients; adding salt to the meat too early will cause the protein to coagulate prematurely, making the meat harder and smaller in size; and adding salt to cold dishes too early , It will make its juice overflow and lose its crispness.

The correct way: when cooking the salt, do not have to rush to put the salt, you can wait for the vegetables to reach the maturity before putting it, or put it before the pot. Remember, daily salt intake should not exceed 6g.

Mistake 6: Do not wash the pot and continue to fry

How many lazy people got shot after seeing this one! After the cooking is finished, some fat will adhere to the pan more or less, and when these fats are heated again at high temperature, they will produce more harmful substances, such as aldehydes, low fatty acids, oxides, epoxides, etc., carcinogens Benzopyrene is also among them.

If you maintain such a bad habit for a long time, it is tantamount to accumulating harmful substances for yourself, increasing the possibility of "cancer".

Correct method: After frying a dish, brush the pan first and then fry the next dish. Pay attention to removing the grease attached to the pan. In addition, the cooking oil that has been fried should not be used repeatedly.

Although these mistakes are small, they will be detrimental to our health in the long run. So if you have these activities, you must quit these habits!
