"It is still a week before the expiration date is expired. I suspect that the freezer for promoting yogurt has been kept open, and the yogurt has deteriorated without reaching the refrigeration temperature." In view of Ms. Li's reflection, the reporter visited many supermarkets in the provincial capital on the issue of "storage temperature", and found that many supermarkets and refrigerators stored food temperatures were difficult to store, and the real "shelf life" of refrigerated food was questioned. Promotion counters: -18 cold storage food bags are filled with small beads. At 8 o'clock in the evening December 10th, the reporter went to visit the Ginza supermarket Quancheng Square shop. Many promotional counters are placed prominently in supermarkets, full of brand yogurt, frozen foods, and meat products. Before the refrigerated food sales promotion cabinet, the reporter saw that the packaging paper on the products such as the beancurd, the sweet and not hot and so on was clearly marked "cold storage under -18 degrees", but the whole counter was not cool. A "fish ball" product is not frozen at all, but the bag is full of small beads. When the reporter asked whether the fish tofu appeared in the cabinet was stored at -18 C in the cabinet, the promoters did not answer directly, but told reporters that "these are basically cooked food, and the preservation can not reach the temperature." You can take it from the bottom of the counter. " Reporters saw that yogurt promotion door has been in an open state. When asked how to preserve yogurt after the purchase, the promoters told reporters: "yogurt storage temperature can be zero." The reporter asked the temperature of the promotion counter at this time, and the salesperson told the reporter, "you can feel it with your hands." This promotion cabinet can be refrigerated, and it is 10 degrees centigrade. " After looking through the product storage instructions, it was found that the storage conditions were kept at 2-6 degrees Celsius, and the promoters immediately said, "the temperature of this cabinet should be below 6 degrees Celsius." Reporters in this nearly an hour, until the supermarket off duty, did not see the staff closes the door, and no one has transported the yogurt to the freezer area. In addition, at the meat food promotion cabinet, the reporter saw that the 4 days below the temperature of the refrigerator, such as the Lee Si Mei ridge, Xi Wang ham and so on. The reporter looked carefully and found that the cabinet had no refrigeration function, and the sausage temperature had basically reached room temperature. Storage refrigerator: Food stacking is higher than cold storage finishing line storage conditions do not pass through the promotion cabinet storage food temperature difficult to reach the standard, refrigerated food refrigerator temperature? The reporter found that the temperature of the part of the freezer in the Spring City Plaza of Ginza supermarket is in the qualified line, but the refrigerated products have accumulated over the finishing line, and many products have not really reached the storage requirements. a thick layer of frost has been formed inside the freezer wall with food rolls, meatballs, chicken and other foods. Mutton rolls, chicken and fillet and other food packaging paper should be kept below -18 C. In the half hour of the reporter's visit, the temperature of the refrigerator has been jumping between -12 and -16 C, obviously, it has not reached the storage temperature. The reporter asked the supermarket promoters whether the frozen chicken fillets would be affected by the poor storage temperature, and the staff said, "there must be no problem. The temperature is now very low. " The ham and Bacon food stored at 0-4 C in the meat product hot selling area are filled with vertical refrigerators, and "DF" appears on the thermometer of the refrigerator, which is not a normal numerical display. When reporters asked why, the supermarket staff told reporters that "DF" means that the freezer is being defrosted. The reporter asked how long the defrosting would take and whether it would affect the shelf life. The staff said, "the defrosting time is a few minutes, and it will not affect the quality of the food." The other two salesmen said they were not sure. "Maybe the refrigerator is refrigerating." Reporters observed for half an hour here and there. The temperature mark always showed the word "DF". In the visit, the reporters found that Ginza supermarkets, the unified Ginza, Carrefour and the big run hair almost all have the words "the food must be preserved under this line". The freezing temperature is difficult to meet the storage requirements of the frozen food and may be made into food deterioration. But many well-known brands such as benefit, Jiabao, Jun Lobo and other yogurt, Heiwang, de lys, Shuanghui and other meat, the products are stacked high out of the refrigerator position everywhere. People in the industry: supermarkets do not refrigerate according to requirements to lead to deterioration in the shelf life. In October 2009, the national standard "supermarket shopping environment" stipulated that the storage of raw materials and raw materials in fresh areas should be equipped with necessary cryogenic storage equipment, including refrigerators (cabinets) and freezers (cabinets), refrigerators, and refrigerators. The temperature of the cabinet is from -2 to 5 C, and the temperature of the freezer (cabinet) is below -18 C. Industry experts say that fast frozen food is required to be stored at -18 C, and -18 is the key point of microbiological reproduction. If the temperature is less than -18 C for a long time, the shelf life of frozen foods will be shortened. In addition, if the freezer is open and food stacking is higher than the finishing line, it may also lead to food deterioration. At the same time, the industry said that once the yogurt does not guarantee storage at the recommended storage temperature, the shelf life will be shortened accordingly, and the accelerated propagation of bacteria leads to deterioration. The storage temperature of milk products such as sour milk and other dairy products is at 2 ~6 C. If the temperature is raised to 15 C, ~20 C, the shelf life will be short half. This time you can not take the shelf life of the packaging as a standard. "Many supermarkets sell yogurt at room temperature for promotions and discounts, so that live bacteria will soon decrease. It is also the case that ham is refrigerated below 4 degrees Celsius. The storage environment is not up to standard, and the shelf life is greatly reduced.
