How can I wash the pesticides off the vegetables? Look at it!

In daily life, washing vegetables and cooking is something we have to do every day, but do you know how to deal with vegetables is the best? How to wash vegetables? How should green leafy vegetables be stored? What's the point of storing cooked dishes? Below, let's take a look.

Do not soak vegetables when washing

Some people are used to soaking vegetables, thinking that this can clean pesticides, in fact not. If the vegetables are not washed clean when soaking, there are pesticide residues, which will get dirtier and dirtier. If the soaking time exceeds 30 minutes, it will also cause vitamin loss. Buy back the vegetables first set room temperature for half a day to let pesticides volatilize, and then rinse with water several times can be.

Green leafy vegetables have good refrigeration effect

Vegetables contain low amounts of nitrite, which reaches its peak in 1~3 days when stored at room temperature, and reaches its peak in about 3~5 days under refrigerated conditions. Spinach, cabbage and other green leafy vegetables, nitrite production is particularly large, so the effect of refrigerator storage is better. Roots such as cucumbers, squash, onions, white radishes, carrots, etc., do not need to be placed in the refrigerator. The enzymes contained in these plants will slowly decompose pesticide residues.

Cold salad with garlic

Organic sulfides in garlic juice, vitamin C in lemon juice and other reducing substances can block nitrite synthesis nitrosamine carcinogens. When cold vegetables or pickled vegetables are mixed, adding onions, ginger, garlic and pepper is beneficial to reduce the content of nitrite.

Turn less before preservation

Leftovers often have problems with excessive nitrite. Nitrite itself is toxic and meets protein in the stomach, producing carcinogenic nitrosamines. Many bacteria have nitrate reductase, which reduces nitrate to nitrite. Therefore, it is best to fry the vegetables to be stored immediately and put them into the refrigerator after cooling. Leftovers taken out of the refrigerator must be returned to the pot at high temperature before eating to completely kill bacteria.
