The hope of copying is helpful to you. Xinhuanet Tianjin Channel July 2 1 Sunday People always like to choose bright colors and high moisture when buying melons and fruits, but they often feel less sweet and delicious when eating them. Now is the season of abundant fruits. People bring seasonal fruits home almost every three or two days. But if you knew that these fruits had been "beautified" with sulfuric acid, industrial citric acid and various liquids, would you still pay for them? A few days ago, an unannounced visit group made an unannounced visit to some fruit markets in our city and found that there were unknown secrets behind fresh fruits. [Unannounced visit site] Litchi Yangmei Recently, the unannounced visit team, led by the insider Mr. Wang, came to Wangdingdi Fruit Wholesale Market. Although it is still early, the market is already very lively. The unannounced interview team found that the fruits on many vendors' trucks were wet, and the whole market was turned upside down. Only two or three fruits are dry and look cleaner. Mr. Wang told the unannounced interview team: "Most of them are wet, because the ice cubes used for preservation are melted and soaked, but many of them are soaked with preservatives. If you don't look carefully, even we may be fooled. " After many twists and turns, the unannounced interview team found that a vendor went straight to a row of bungalows on the north side of the market after eating fruit. It turns out that all the vendors here sell fruit preservatives. The unannounced interview team noticed that these vendors bought as little as one bottle of preservatives as three or four bottles. The vendors kept taking goods out of the house, and they were all as busy as a bee. The unannounced visit team went to watch and found that there are many kinds of preservatives for different fruits. In addition to the words fruit preservative, each bottle of preservative is also marked with the words national patented product, but there is no name and address of the manufacturer. Strong acid preparation lights up as soon as it is sprayed. Mr. Wang told the unannounced interview team with his eight-year experience in fruit business that these "preservatives" are actually a mixture of dilute sulfuric acid, industrial citric acid and water. In order to prove his words, Mr. Wang poured the preservative bought by the unannounced interview team on the concrete floor. A string of white bubbles immediately appeared on the concrete floor, and then there were bursts of smoke in an instant. After dropping this preservative on the pH test paper, the test paper instantly turns purple. All these indicate that this is a strong acid preparation. Mr. Wang said that in the fresh-keeping business, it is common to keep fresh with sulfuric acid. Almost everyone does this. Some wholesalers even send a bottle of preservative for free when selling fruits. Moreover, the method of keeping fresh with sulfuric acid is not only used on litchi exposed by the media, but also on bayberry, plum and other fruits. Because the preservation methods of these fruits are very limited, they can only be frozen, and these fruits are particularly prone to discoloration. Therefore, in order to sell well, some retailers without large-scale refrigeration equipment use the method of spraying sulfuric acid water to "beautify" the preservation. It only takes a few minutes to spray a preservative, and the blackened litchi will become bright and beautiful, even fresher than the one just picked from the tree.
Peach industry citric acid soaked red peaches Before the wholesale of "red peaches", the unannounced interview team noticed that these peaches were particularly red and the color of the whole peach was very uniform. In order to find out, the unannounced interview group spent 30 yuan to buy 5 Jin of "red peaches", and took the opportunity of buying peaches to talk with middle-aged women selling peaches. "Peaches are perishable. What if it can't be sold that day? " "Don't just use liquid medicine for processing, it's especially red!" The woman mysteriously told the unannounced interview team that she picked up a mineral water bottle filled with transparent liquid and sprayed it on the "red peach". While spraying, she said, "This is pure plant fresh-keeping water prepared by myself." For the raw materials of this fresh-keeping water, the woman avoided answering. The woman also told the unannounced interview team that all the "red peaches" except her were "pickled" with liquid made of industrial citric acid, and the soaked peaches would become fresh and red. The unannounced interview team found that there were four or five carts selling peaches nearby, with several bottles of mineral water bottles filled with transparent liquid. Vendors sprayed peaches with this liquid every once in a while, and the peaches on these carts were all the same red.
