Tomatoes are not reliable, experts teach people to buy safe vegetables.
recently, many city farmers market found poisonous bean sprouts, so that the common people are worried about the safety of the vegetable basket. In May 11th, Liu Fushui and the national public nutritionist Hu Ling, the deputy manager of the Shandong Kuang mountain agricultural product comprehensive trading market and the national public nutritionist Hu Ling, came to the Kuang mountain vegetable wholesale market and the weft six farmer's market to understand a variety of vegetables. The secret of buying and buying.
[green bean sprout] may have pesticide
the same is the green bean sprout, some used pesticides, some are natural growth; some are very fresh, some have become old, how to use the naked eye to distinguish the difference? In the Kuang mountain vegetable wholesale market a green bean sprout stall before the bean sprout planting experience of Liu Fu The water was explained in detail for the reporter. "Choose bean sprout must choose a root, bud stem do not be too strong, with no use of pesticides, yellow bean sprout appearance can not be seen, but green bean sprout can be seen from the color of bean sprout, no pesticide application of green bean sprout, bean sprout skin is green, used pesticide, bean sprout skin is brown black." Liu Fushui said, "again how to identify the freshness of the bean sprouts, most of the bean sprouts shipped to the market are in the water. If you smell a light alcohol, it is not fresh enough to show that the bean sprouts have been soaked in the water for the night. In addition, sprouts sprout green sprouts on the top of the buds, and the brown stems appear on the stems, indicating that the sprouts are longer and not tender.
[tomato] don't buy an angular
a lot of "block heads" sold in the farmers' market. The diameter is more than 10 centimeters and it looks very red. Many businesses call themselves persimmon heads. According to experts, a big persimmon is not necessarily reliable.
in the weir six Road farm market, Hu Ling pointed to several tomatoes and told reporters that buying tomatoes depends on shape and color. "Persimmon with angular, strange shape, or papillary protrusions in the middle are all malformed. It is effective to use hormones when planting." She said, "the color of the tomatoes that did not use ripener would not be very red, but red and green, and the public should also pay attention when buying anti season tomatoes."
Hu Ling said, now there is an Israeli tomato called fruit and persimmon in the market. The fruit is only seven or eight centimeters in diameter, and the peel is orange red with fresh ARCIS. The price is more expensive than the other tomatoes that sell well, but the safety is higher than that of the ordinary tomatoes.
cucumbers are more comfortable with
in the memory of many elderly people, cucumbers are curved rather than straight on the market. Although vendors claim that cucumber straightening is the result of technological improvement, Hu Ling believes that curved cucumbers are more reassuring.
according to her understanding, now the cucumber straightening is out of good looking consideration. "As long as the medicine is used 'Nen long straight', the cucumber can grow straight and smooth, and it is easy to buy in the farm shop." She said that not only cucumbers, but also because the use of "tender long straight" will become long and long.
(lotus root) skin drying and soil storage
a lot of lotus root are wet in the farmer's market, and some are still very tender and fresh, but experts think this lotus root is not easy to store, and the lotus root is still hidden in safety.
in the weft six Road farm market, Hu Ling took the reporter round, and finally found the lotus root that she thought was reassuring. I saw that this lotus skin was dry and stained with a lot of soil. It was not processed at first glance, but it was clean after cutting. Hu Ling said that the lotus root refrigerator will not rot for three or four days, but the market sale of lotus root even if put into the refrigerator is also easy to black and deteriorate, "if the sale of lotus root is very clean, also to improve vigilance, because the merchant may use sulfur yellow water washed".
lettuce does not fight pesticide. No fertilizer
is also leafy vegetables, many vegetables are easy to produce worms, but lettuce is far away from pests.
according to Liu Fushui, according to Liu Fushui, when the weather is warm, the growth cycle of lettuce is more than 40 days, it is short, and the insect is too late to mature, so there is no need for the use of pesticides. At the same time, lettuce ball is also a vegetable without fertilizer, because once the fertilizer is used, it will only grow long, so farmers only use chicken manure to make fertilizer.
[letinous edodes] "umbrella" is solid and round and nutritious high
letinous edodes must be bigger and better. Not necessarily.
Hu Ling told reporters when choosing letinous edodes, the most important thing to choose letinous edodes is to see whether the umbrella is complete and compact. "A lot of people like to choose the big umbrella, in fact is a misunderstanding," Hu Ling said, "the quality of the letinous edodes' umbrella 'is not necessarily large, but to be tight and round, there is no fissure, so as to retain the nutrient components."
the smooth skin of the vegetable is not easy to hang a pesticide
smooth skin, which not only makes many vegetables look very watery, but also puts them on a layer of pesticide protective clothing. Liu Fushui said, eggplant, pepper and other vegetables thick and smooth, pesticide is difficult to attach to the above, and weak internal absorption, as long as one or two times to remove pesticides, eggplant peeling better effect, such vegetables generally will not have pesticide residues risk.
