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 by 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 pay attention. For example, the leaves of vegetables have lost their usual green color and are dark green, and the green color of edamame is abnormal. They may have been sprayed or soaked with methamidophos pesticide before harvesting and are not suitable for purchase.
Step 2 look at the shape
Vegetables with normal shape are generally cultivated in a conventional way, and can be safely eaten without being treated with hormones and other chemicals. "Abnormal" vegetables may be treated with hormones, such as leeks. When its leaves are particularly broad, which is 1 times wider than common broad-leaved leek, hormones may be used in the cultivation process. Hormone-free leeks have narrow leaves and have a strong fragrance.
Step 3 look at the freshness
Excessive application of nitrogen fertilizer (such as urea and ammonium sulfate). ) will cause serious nitrate pollution of vegetables. Through the sampling inspection of vegetables in the market, it is found that the order of nitrate content from strong to weak is: root vegetables, potato taro, green leafy vegetables, Chinese cabbage, onion and garlic, beans, melons, eggplant fruits and edible fungi.
The rule 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 eat vegetables correctly, and try to eat more melons, fruits, beans and edible fungi, such as cucumbers, tomatoes, edamame and mushrooms. Many consumers believe that there are many wormholes in the leaves of vegetables, which shows that eating this vegetable is safe and does not require drugs. In fact, this is not reliable.
Whether vegetables are susceptible 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, cauliflower and so on. If you have to spray medicine frequently, it will inevitably become a "multi-drug vegetable" with serious pollution. The amount of chemical fertilizer applied to various vegetables is also different.
