Food safety tips: Distinguish between food shelf life and best before date
Original title: Food safety practical stickers: The difference between food shelf life and the best edible period
¡¾ Global network comprehensive report ¡¿ According to the French "Le Figaro" reported that food safety has been one of the focus of attention. According to laws and regulations, the food label should indicate the food shelf life and storage conditions. Is all food beyond its expiration date deemed inedible? Experts say it's important to distinguish between a food's best before date and its sell-by date to determine whether it's edible.
one.
The shelf life of food indicates that the food is eaten several years, months and months before the expiration date, after the expiration date is eaten, such food will cause harm to human health, especially perishable food, after the expiration of people are prone to infection with Salmonella, animal bacillus and so on. Therefore, we should eat this kind of food within the expiration date. But normally, the labeled shelf life of food is shorter than the actual shelf life. That's because lab workers change their storage conditions during testing to see if special storage methods are needed. Therefore, if we eat them within 24 hours of their expiration date, it won't do much harm to our health. However, the degree of harm depends on the type of food. Yogurt simply turns sour when it's past its sell-by date, while eating cooked foods like pork and fish that have expired can be a serious health hazard.
The best time to eat food indicates that it is best to eat several years, months and days before, which often appears in beverages, canned food, coffee and other foods. After the best edible period, this kind of food can still be eaten, but its taste and nutrition can not be guaranteed. For example, cakes will become more boring, fruit juices will lose vitamins and so on.
two. Food storage tips
After opening the food, do not store it before the shelf life. The shelf life of food is the period of time that it can be stored under normal storage conditions, such as it must be stored in the refrigerator or in an airtight state. However, dairy food, meat food, etc., once opened, no matter how long its shelf life is, must be consumed within 48 hours.
Be very careful when refrigerating foods that are about to expire. It's best to put the number of days left on the label, because once the food is defrosted, we only have so many days left to eat.
Never refrigerate foods that are past their use-by date. Because even though refrigeration can stop the growth of bacteria, it can't kill the bacteria that are already there. Therefore, when the food is thawed, the bacteria multiply just as quickly, and eating it is also at risk of food poisoning.
three. Distinguish between inedible and edible food categories
Inedible foods:
Signs of mold in breads, cereals or dried fruits;
Plastic packaging bags of meat and its products expand;
moldy phenomenon appeared in beverage products such as juice, fruit puree, etc.;
Meat, poultry or fish have strange odor or mucus;
eggs in water, faded expiration dates printed on the eggs or cracked eggs indicate the possible presence of salmonella. Note that eggs are the number one cause of food poisoning caused by bacteria that we can't risk our lives with.
Edible foods:
Foods such as honey, rice, chili, candy and noodles can be kept for several years after their expiration date. Because bacteria don't thrive in these foods, the only downside is that they taste bad after the expiration date. (Wenqing Lin and Yizhen ZHAO)
