summer scorching, very hot. Many people like to buy ice cream or ice cream for the summer. Recently, some people reported to the newspaper that they bought the ice cream from the supermarket last year, although the above shelf life is two years, but it always feels a bit worried. The reporter also conducted many interviews, for this "old ice cream", nutrition experts said that if the frozen environment to meet the standard, as long as no warranty period, generally will not be a problem. However, if the ice cream is deformed and laminated, it will probably be frozen after melting. This ice cream should not be eaten as much as possible. Shandong Commercial Daily trainee reporter Yu Na Xuan Xiaoxia is not uncommon. Is the problem reflected by the public widespread in the Ji'nan market? Reporters visited several large supermarkets and found that ice cream was still on sale in the next year. The reporter visited large mart, Tesco, Carrefour and other large supermarkets found that most of the supermarket's ice cream production date is close, mostly from March to May this year. At Carrefour supermarket, reporters found two boxes of cold drinks made last year, the "Yili ice lolly" produced in May 2014, which is being sold in the form of 8 packed cartons. The other is the "wall's love sweet cone" produced in December 2014, which is currently on sale in 6 boxes. The cone is sold in a variety of flavors, ranging in price from 19.5 yuan to 24 yuan. In the supermarket, the reporter also found a new year's ice cream named "bright snow white brick". The date of production of this cold drink is marked with steel stamps. The package shows that the product has a shelf life of 24 months and sells for 4.8 yuan. Ms. Li, who is buying ice cream, says she generally does not pay much attention to the shelf life of ice-cream: "I usually do not see the date of production, sometimes I buy ice cream at the roadside store, eat it, lose it, and don't notice the date of production." During the interview, reporters found that people who did not pay attention to the date of production were not very few. Many people were more concerned about taste, price and other factors when choosing ice cream. [discount sales promotion, or old and new mix] "old popsicles buy a box to send a box, 8 boxes per box, 11.8 yuan to take two boxes, it is very appropriate." At a cold drink counter at Carrefour's bus stop, a salesperson showed reporters a box of old popsicles on sale. The old icebox in the freezer is packed with two tapes. Supermarket sales staff said that it was because of the production date too long and choose to promote sales. "The production date is in 2014, but still in the shelf life, so the promotion, after all, only summer is its selling season, once expired, it is not sold." In the "ice Popsicle" adjacent ice cabinet, the reporter saw the 2014 annual production of "wall's love multi sweet tube". Unlike the "old ice lolly", the sweet canister does not sell promotional advertisements, but uses a mixture of old and new products to display in the freezer. The reporter saw that last year's relatively high stock of "taro flavor" and "cherry flavor" sweet tube, in 2015 production and the 2014 production of sweet tube is alternately placed, when the purchase is not carefully watched, it is difficult to notice the difference of the date. Supermarket sales staff said that the temperature of the freezer is about 18 degrees below zero, and ice cream will not deteriorate. However, some people also expressed concern about this, "the time has long been stored for a long time is not good, if the ice cabinet is not timely cleaning, do not know whether or not it will affect the health and quality of ice cream." As far as the ordinary consumers are concerned, it is difficult to know whether the ice cream is in a standard freezing environment before the entrance. Du Huizhen, director of the Nutrition Department of Qianfo Hill hospital, told reporters, "the quality of life is only one of the criteria for identifying whether the" aged ice cream "is deteriorating. In theory, ice cream is generally qualified for a whole set of cold chains stored and sold. But if it melts or the package is damaged, it will not work again. Ice cream is a kind of food with high fat, high sugar and high protein. If it is not properly preserved, it will easily breed bacteria. Consumers may cause gastritis or diarrhea after eating. " "There is no testing equipment in the hands of consumers," Du Huizhen said. "To identify the quality of the ice-cream for the next year at most from the appearance of the preliminary identification, such as color, taste or outer packaging. Of course, the newer ice cream on the date of production is sure to have a higher safety factor. In case of choice, it is suggested that you buy newly produced ice cream. A lot of deformed and caked ice cream is likely to melt, and there may be hidden dangers.
