小売店のデリは早くて使いやすい, そしておいしいです. テンポの速い現代人の生活にぴったりフィットします. しかし, when we buy them in the evening, people frequently question whether they are still as fresh and delicious as when they were first made. Has it started to deteriorate?
How long can you keep it fresh?
According to the United States Department of Agriculture data: Unopened luncheon meat can be preserved in the refrigerator for two weeks; しかし, if opened or purchased from a deli, sliced luncheon meat can be frozen for three to five days. If it changes color, smells foul, or becomes sticky due to incorrect storage, discard it immediately.
What could have caused this?
Temperature has a considerable effect on the rate of meat deterioration, particularly at differing temperatures. At 5°C, beef rotting increases threefold compared to 0°C, and at 10°C, corruption increases fivefold. At the core of this phenomenon is an increase in the surface temperature of meat.
しかし, in the retail environment ensuring that meat cabinets remain at the proper low temperature is a complex and demanding task. On the one hand, the built-in lighting system not only provides necessary lighting, but it also emits heat and ultraviolet radiation that cannot be ignored. These additional factors frequently cause the actual surface temperature of fresh meat to be much higher than the temperature measured by the instrument in the cabinet, accelerating meat deterioration. On the other hand, customers’ frequent opening and closing of display cabinet doors not only disrupts the temperature stability inside the cabinet but also causes a continuous influx of warm air from the outside world, exacerbating the temperature fluctuation inside the cabinet, and posing an additional challenge to meat preservation. Choosing the correct lighting for a retail store is essential, especially for food displays. Good lighting may not only improve the visual effects of goods, but also draw customers’ 注意, and assist increase the shelf life and freshness of food.

結果として, ready-cut prepared food sold in supermarkets after a day of display and sale is sure to be less fresh than when it was first baked. To ensure food safety and the optimum taste, consumers should consume within a day after purchase. If they cannot be used immediately, they should be stored in sealed bags or containers to limit bacteria development and food oxidation, and consumed as soon as possible the next day to ensure food freshness and safety.
Is cooking safe for the deli?
Many people believe that heating cooked food in the microwave at high temperatures successfully kills bacteria, which is accurate in most circumstances. Microwave ovens generate high-frequency electromagnetic waves that cause the water molecules in the food to vibrate swiftly, generating heat and rapidly raising food temperature. When food is heated to a high enough temperature, it can eliminate bacteria and other microorganisms that perform physiological functions, resulting in sterilization. Some heat-resistant bacteria and parasites, しかし, require greater temperatures and longer periods to be killed.
Proper storage of cooked food?
Proper storage is vital for keeping prepared foods fresh and flavorful. Refrigerate at 0-4°C. Place food in Ziploc bags, separating cooked and uncooked ingredients. Eat within 5 days at the latest. To avoid repeated thawing, store frozen in sub-packaged sealed containers and eat within the shelf life.
Tips for spoilage identification of cooked food?
1. Color: look for changes in color. If It’s dull, dark, or spotted, it may have gone bad. Color is an important index to judge whether the cooked food is spoiled.
Texture: compared to the original texture, if it becomes sticky or hard, it can be a sign of deterioration.
3. Smell: cooked food spoilage will generally give off an unpleasant smell
4. Taste: Taste is the most direct way to determine whether cooked food is spoilage, but to pay attention to safety.
5. 包装: look for leaks or breakage in the packaging. If there is a problem with the former, it is likely to have gone bad.
Finally, we should remind everyone to clean their refrigerators regularly. Because goods in the refrigerator are mingled together, it is simple to cross-taste, which breeds a wide range of germs. Clean and disinfect your refrigerator at least once a month. Harsh disinfectants are not suggested. Because they damage refrigerators, they provide a hiding spot for bacteria.
