Now is the peak season of fruit sales, and many merchants often cover the cut fruit with a layer of plastic wrap to expose delicious pulp to attract customers. However, through investigation, it is found that many fruit stalls use plastic wrap without any logo. Experts in the quality inspection department reminded that if the identity of plastic wrap is unknown, consumers must pay attention when buying food, because PVC film has carcinogenic effect on human body.
The pulp is stained with the plastic smell of plastic wrap.
Why do watermelons kept fresh in the refrigerator smell bad? Ms. Zhang, who lives in Taibai Road, recently encountered such a strange thing.
Ms. Zhang bought half a watermelon after work. In order to prevent the watermelon from stinking in the refrigerator, she deliberately left the plastic wrap on the watermelon. The next day, I opened the refrigerator to prepare for dinner. As soon as I tore open the plastic wrap, I smelled a plastic smell in the meat. Later, in order to eliminate the odor, the top layer had to be cut off. Ms. Zhang said: How can people eat food with this inferior plastic wrap?
Coincidentally, Aunt Cao, who lives in the East Community, also encountered an annoyance. ? The freshly heated braised pork has a plastic smell, and the grandson said that it has gone bad. ? Aunt Cao said that the braised pork was cooked too much the day before, so it was wrapped in plastic wrap and put in the refrigerator. The next day, after taking it out and heating it in the microwave oven, it smelled like plastic and she had to dump the meat. ? It may be that last time I was greedy for cheap, I bought plastic wrap with poor quality. ?
Is the fruit stand multifunctional? Three no? preservative film
Yesterday morning, in fruit stalls and supermarkets in markets such as Zhuque Road and Taiyi Road, many vendors cut watermelons to attract customers, and all watermelons were wrapped in plastic wrap. The stall owners said that in order to prevent the watermelon pulp from oxidation, they specially wrapped a layer of plastic wrap.
At Taiyi Road Market, a stall owner who did not want to be named said that the price of watermelon is high now, but as long as it is 80 cents, the profit is very thin. If you go to the supermarket to buy plastic wrap, it will increase the cost invisibly, so they are all wholesale in the wholesale market. The stall owner was a little wary when he heard that this kind of three-no plastic wrap would have an impact on the human body. Our plastic wrap will never be harmful to human body. Have you ever heard that plastic wrap eats bad people? In a fruit shop, I saw a clerk wrapped a plastic film on a plate of grapes, and there was no sign on the surface of this roll of plastic film.
Yesterday, I came to a wholesale market in Changle Road. In front of a packaging bag booth on the east side of the first floor, there are all kinds of plastic wrap. The color of small roll plastic wrap is transparent, and the color of large roll plastic wrap is yellow, while the outer packaging of all kinds of plastic wrap is simple plastic film, and there is no basic information such as trademark and manufacturer.
This kind of plastic wrap is imported, and the food wrapped in it will keep fresh for a long time. It's very easy to use. Many fruit sellers buy it. ? When I said that, why didn't even have the name of the trademark factory on the plastic wrap? The stall owner showed a disdainful look: I want to buy something with logo and go to the supermarket. Expensive and good. ?
Hotels and food stalls also generally use inferior film.
Then, according to the guidance of a fruit stall owner, I came to Nanning market. On the sidewalk on the market side, almost every household is selling several kinds of yellowish plastic wrap. This plastic wrap, which looks like tape, has no logo except a few English letters. A stall owner said:? This kind is very easy to use, and many big hotels get their goods here. ? But where are these plastic wrap made? The stall owner shook his head and said. Don't you know? .
Another stall owner said that hotels and food stalls buy this kind of plastic wrap for packaged food, which sells well. Expressing doubts about the quality of this plastic wrap without any logo, the stall owner said that the box containing this plastic wrap has the manufacturer's logo. Later, she took out a paper box. Although there is a manufacturer on the box, there is no product material or QS logo.
Is the plastic wrap sold in the supermarket also unmarked? Visited some supermarkets. In the plastic wrap monopoly area, there are many plastic wrap brands on the shelves. Pick up any brand at hand, and its packaging has obvious QS logo, and the production date and shelf life of the product are marked. For the use temperature of plastic wrap, the wrapping paper has strict restrictions, and the merchants also indicate it on the packaging of plastic wrap? Precautions? .
It is understood that the vast majority of plastic wrap sold on the market at present, like common plastic bags, are made of ethylene masterbatch. According to the different types of ethylene masterbatch, plastic wrap can be divided into three categories.
The first is polyethylene, or PE for short. This material is mainly used for food packaging, such as this film for fruits and vegetables we usually buy, including semi-finished products bought in supermarkets. Then the second one is called PVC, which can also be used for food packaging, but it has a certain impact on human safety; The third type is polyvinylidene chloride (PVDC), which is mainly used for packaging cooked food, ham and other products.
Experts said that among the three kinds of plastic wrap, PE and PVDC are safe for human body and can be used safely. But PVC cling film is more harmful to human body.
Pay attention to whether there is a QS mark when buying.
In view of the problem that some plastic wrap films are not labeled, experts from Guangxi quality inspection department said that on June 0, 20 10, 12, the General Administration of Quality Supervision, Inspection and Quarantine issued a new national standard for plastic wrap films for food, stipulating that food packaging materials are not allowed to sell products without QS labels.
The expert said that when consumers buy plastic wrap products, they must go to regular hypermarkets. At the same time, we should also pay attention to the material marked on the outer packaging of plastic wrap, marked as? PE？ And then what? PVDC？ Two kinds can be used safely as needed, and? PVC？ Plastic wrap contains carcinogens, which is harmful to human body. At present, the plastic films used by vendors of some fruit stalls and cooked food stalls are unknown. If there is no logo, it can't be used to package food according to relevant national regulations. If consumers find food packed with unmarked plastic wrap, don't buy it.
