How to choose safe vegetables

Do not choose unusual seasonal and green fruits and vegetables. The fruit should be selected intact, healthy, not crushed. When washing fruits and vegetables, soak them then wash them, then soak them in salt water.

Pinch fruit, interstitial leaves are places where pesticides are deposited

Dr. Dang Thi An - Pho Do not choose unusual seasonal and green fruits and vegetables Environmental chemistry (Ecological and Biological Resources Institute) - says: "A pot of soup should have many types, including tubers, whole leaves . to limit the risk. muscle poisoning more ".

Eating vegetables should eat the leaves, while the stalks, if eaten, must be blanched with boiling water, as many vegetables are contaminated with nitrates. This substance goes from soil to vegetables mainly through roots and contained in stalks. Nitrate is easily soluble in water, so when it comes to vegetable stalking, it is easy to dissolve.

Dr. Do Quang Huy - Gas Chromatography Development Center (Hanoi University of Science and Technology) advised: "The fruit or interstitial knob is the place where most of the pesticides and drugs grow."

Because in fruits and vegetables, this part is often concave, so water and chemicals often settle. Vegetables on the surface of the epidermis, which absorbs a lot of chemicals when irrigated. So, soaking and washing vegetables will remove most of these substances.

So soak vegetables and wash. It is best to soak vegetables in light salt water or purple medicine after washing. Because salt and potassium permanganate increase the dissolution process, diffuse the toxins, push them out of the vegetables by water. "

Do not like nice code

Even those vegetables just need to be left from morning to afternoon, they wilt.

For water spinach, if the boiled water is green, it is due to high nitrogen fertilizer. Usually vegetables without growth stimulants have big, hard tubes. Water spinach in polluted water when chopping raw ends often does not curl.

The feeling of fruits must be heavy and brittle. Vegetables sprayed with growth stimulants are usually lighter. Do not choose fruits and stains on the petioles, fruit nipples, fruit stalks .
