Nowadays, though the large supermarket is in full flourish, a lot of people like going to the market of farm produce near the Residential Area even more, the rice of buying vegetables amount, convenient and substantial. However, some pedlars are in order to make profit, may have played some wiles that you do not know. It is please be in the industry in this issue the personage in the know is a revealed secrets of ours.
The secret one: The fade leaf dish drenches water to pretend to be freshly. A lot of people think the vegetables in the market of farm produce are the freshest, because the dish there comes from the vegetable grower directly, or say, the dish is planted in the own field, catch and just collect early on the same day as some retailers. But after the reporter visits 7 markets of farm produce in Chaoyang District, Beijing, Haidian District, find the so-called fresh vegetables, a lot drench fade vegetables some water, or soak and pretend to be clear-cutly with water. The food institute's professor Jiang WeiBo of China Agricultural University tells " life Times " reporter, this kind of phenomenon is aptest to take place on green leaves vegetables, because consumers are often fresh and green with dish leaf color, the surface is it is judged fresh degree of them that water is moist and glossy.
The expert gives an idea: Don't be thought the vegetables of the morning market and must not be just collected from the vegetable plot until the same day, it is bought to sell from large-scale wholesale market that the dish in the market of farm produce is big, selling out on the same day will also certainly catch and sell, so, must learn to distinguish by oneself. Green leaves vegetables such as spinach, rape, bean-leaf are aptest to spray water, if the apex wilted or the skin blade has been peeled off, it will be probably imitative fresh dish. In addition, the leaf dish gloss that wilts, drenches water fails, and there are water stain and spot pieces, this is formed through cell damage. The vegetables such as young soya bean, fresh kidney beans, can try to push the pod inspection aside. Without fresh young soya bean soaked with water, the beans are wrapped up by the white membrane around; Soaked with water, the beans will be independent from membrane.
The secret two: Make and have the light and turn on the electric fan, the prepared food seems to be delicious and soft. There is a prepared food stand in each market of farm produce, the reporter notices, no matter enema made by oneself, Smoked Liver, or captivating duck neck, chicken leg, mostly put in the glass cupboard, shine in morning and evening with the fluorescent lamp not high of a degree, the ceiling fan is hung on the direct top, the above is a white towel, rotate and drive away fly's mosquito ceaselessly. The food institute's associate professor Fan ZhiHong of China Agricultural University tells reporters, the shining of light can let prepared food color seem extremely red and soft and fresh, the warm tones light such as being especially pink, function is more obvious, let people see appetite. The ceiling fan can not totally drive flies away to transfer to the towel in fact, but leave a impression with neat hygiene on somebody, still can propagate the taste of the prepared food out. Some people plan, buy prepared food originally, smell the intersection of taste and the intersection of view and color, will aroused in interest to buy some. But get home, see suddenly, prepared food color might on being so tender, can also maybe take the bad stomach.
The expert gives an idea: Select the prepared food to make sure " Two is seen " , " smell " , " taste " . " two is seen " Refer to: Whether one is seen the counter which is put the prepared food is airtight on four sides, there are flies and dusts around; Get the prepared food outside the counter two times, see whether the color is tender, if turn black or the color and luster is too red, don't buy. " smell " Whether mainly have peculiar smell to hear, so as not to buy back the rotten products. " taste " Demand to have a trial test voluntarily, if taste is over-salty, may process the brine because of putting long, had better buy few for the health.
The secret three: The morning city of melon and fruit that accelerates the ripening, the high flavor of the price has no nutrition badly. Eat water-melons in winter, eat peaches in spring, often there are the newest and early-maturing melon and fruit to sell on the market of farm produce, but taste have a long way to go with whom people imagine buy back home, because they " the a ripe one " probably ," the a familiar one that accelerate the ripening " . Nutritionist of head of the department of the nutrition of Shanghai East China hospital Chen XiaFei tells reporters, for the morning city, sells for a good price, the retailer may make some tricks to the underdone or half-mature melon and fruit. For example put in the wheatgrass and seal hot period after the tomato is half-mature, the color is red, there is not but one's own taste; Mostly 70%-80% skillful to traffic in bananas had from the South, after the pedlars buy goods wholesale cheap, spread a layer of ripener on the underdone surface of banana, in a two days, the banana became glistening yellow; Strawberry, peach,etc. too might use ripener, appearance ripe and goodlooking, taste but very much poor, give a great discount too in original nutrition.
The expert gives an idea: Try hard to buy more seasonal melon and fruit, cheap, taste is pure. If really want to eat it against the season melon and fruit, you had better not buy more each time, demand to have a trial test before buying, if the pedlar refuses, will probably accelerate the ripening, taste is not good.
The secret four: Shrimp's bubbles are fresh that the dead fish die. A few days ago, the medicines supervision department of Shanghai food sent out the urgent notice, demanded to investigate and prosecute within the range of the whole city and was suspected of being involved in " washed shrimp's powder " which violated food additive regulation . Notice point out some the intersection of agricultural trade and the intersection of aquatic products and at the clean lobster stall owner of market, will use " Wash shrimp's powder " ,Soak by it, original color is dark red, and hides the little lobster with black impurity, make the color and luster vivid. One of National Aquatic Products Quality Control and Inspection Center examines personnel to say, they find too while spotting check the aquatic products of market of farm produce, some pedlars will soak the fishes and shrimps with aqueous solution which contain formaldehyde, let them be difficult to be rotten, seem fresh, but people may present indigestion, regurgitation, vomit etc. and react after eating the fishes and shrimps soaked, influence the health.
The expert gives an idea: The fresh water aquatic products tries hard to buy alive or icy, learn to distinguish: Fresh fish eyes bright and transparent and eyeball break out, gill cover close, the intersection of gill and pink or red slice, the fish scale is bright, neat. The shrimp of high quality, the head, body link up closely, outer cover and shrimp's meat are stuck to into an organic whole closely, feel hard and flexible when with hands, according to shrimp's body.
