Purchase method:
1, look at the color
There are many kinds of vegetables with different nutritional values. Generally speaking, it can be divided into two categories according to color: dark green leafy vegetables, such as spinach and amaranth; These vegetables are rich in carotene, vitamin C, vitamin B2 and various minerals. Light-colored vegetables, such as Chinese cabbage and lettuce, are rich in vitamin C and low in carotene and minerals.
Some vegetables are abnormal in color, so attention should be paid to them. For example, the leaves of vegetables lose their usual green color and are dark green, and the green of edamame is abnormal. They may have been sprayed or soaked with methamidophos pesticide before harvesting, so it is not suitable to buy them.
2. Look at the shape
Vegetables with normal shape are generally cultivated conventionally and not treated with hormones and other chemicals, so they can be safely eaten. "Abnormal" vegetables may have been treated with hormones, such as leek. When its leaves are particularly wide and thick, which is 1 times wider than common broad-leaved leek, hormones may have been used in the cultivation process. Leek leaves without hormones are narrow and have a strong flavor when eaten.
3. Look at the freshness
Excessive application of nitrogen fertilizer (such as urea, ammonium sulfate, etc.) will cause serious nitrate pollution in vegetables. Through the sampling inspection of vegetables in the market, it was found that the order of nitrate content from strong to weak was: root vegetables, potato taro, green leafy vegetables, Chinese cabbage, onion and garlic, beans, melons, eggplant fruits and edible fungi.
The law is that the pollution degree of roots, stems and leaves of vegetables is much higher than that of flowers, fruits and seeds. This law can guide us to correctly consume vegetables and eat as many melons, fruits, beans and edible fungi as possible, such as cucumbers, tomatoes, edamames and mushrooms. Many consumers believe that there are many wormholes in the leaves of vegetables, which indicates that it is safe to eat this kind of vegetables without drugs. In fact, this is unreliable.
Whether vegetables are vulnerable to insect pests is determined by the different components of vegetables and the specificity of odor. Some vegetables are especially favored by pests, such as green vegetables, Chinese cabbage, cabbage and cauliflower. If you have to spray drugs frequently, it will inevitably become a "multi-drug vegetable" with heavy pollution. The amount of chemical fertilizer applied to various vegetables is also different.
