Although the nutritional value of quick-frozen food is comparable to that of fresh food, the wrong preservation and thawing methods will seriously affect the nutrition and safety of these foods.
If you spend the original price to buy the food, the nutrition and taste of the food you eat will drop, and you will have to pay for the refrigerator electricity bill, which is really not worth it…
Therefore, Dr. Clove has prepared a [Quick Frozen Food Strategy] for you, and you will not thank you for taking it away ~
Frozen food, this is the right choice.
There are so many frozen foods in supermarkets, how can you choose delicious and safe ones?
1. Try to choose big brands
Generally speaking, no matter in cold chain transportation or production and processing, big brands are more guaranteed in quality.
2. Pay Attention to Shelf Life
Although the shelf life of quick-frozen food is long, it is still necessary to choose those products that are close to the production date. When eating, try to finish the quick-frozen food that is close to the shelf life first.
3. Buy in supermarkets with perfect freezing conditions and reliable reliability.
What affects the nutritional value of quick-frozen food most is not quick-freezing itself, but cold chain preservation in the sales chain.
Generally, quick-freezing requires that it cannot be thawed during the whole storage process. However, in many places, the cold chain cannot be guaranteed, which easily leads to partial thawing of quick-frozen food during transportation and storage, thus causing a large number of microorganisms to multiply and affecting nutritional value and safety.
Therefore, when buying frozen food, one should first check whether the freezer and refrigerator are in good condition. If there is no good freezing condition (especially some supermarkets will turn off the power supply of the freezer at night), it is better not to buy it.
4. Choose products that are well packaged and free of ice cubes and crystals.
Try not to buy quick-frozen food in bulk, especially all kinds of meatballs and hot pot balls. Although packaged quick-frozen food will be slightly more expensive, it is relatively safer and more hygienic.
Fresh frozen fish, meat, shrimp, dumplings or vegetables and other commodities are uniform in texture, and there are no ice cubes or ice crystals in the package. However, if large ice crystals and ice cubes are formed due to temperature fluctuations during transportation and storage, the commodities inside may adhere, and more and more ice crystals and ice cubes will appear in the package.
At this time, the quality of the food has obviously decreased, and the taste and flavor will be greatly reduced. Therefore, when selecting frozen food, you should carefully look at the status of the goods and buy it carefully when you see ice crystals and adhesions. If you buy it home, eat it as soon as possible and do not store it for too long.
5. When shopping in the supermarket, buy frozen food at the end.
Many people put frozen food into the shopping basket as soon as they arrive at the supermarket, and then went shopping for 1 or 2 hours before checking out and leaving. Little imagine, the temperature in the supermarket is not low. From the time the frozen food leaves the freezer to the time you go home and put it in the refrigerator, bacteria have already started to camp on your frozen food in these hours.
Therefore, when shopping in the supermarket, please buy quick-frozen food at the end. If you can’t eat it immediately after you buy it, put it in the freezer compartment of the refrigerator immediately.
There is a trick to preserve it.
It is not enough to buy the right one, but it must be saved.
It is estimated that 90% of the people have made the following typical mistakes…
Error 1: Put frozen food in the refrigerator and you will feel all right.
Refrigerators are not safes. Even quick-frozen foods with long shelf life will oxidize fat, reduce vitamin content and deteriorate quality and taste over time.
Correct approach: Buy less at a time, and it is best to eat it within two months.
Error 2: The freezer was full and all kinds of food were piled together.
Because different foods stored in the same space will spread bacteria to each other, which is easy to spoil food. You need some [refrigerator helpers] to ensure food safety.
Different foods are best stored in separate packages and frozen, avoiding being put together with other raw fish, meat, poultry and other products. Unopened or damaged frozen foods should be eaten as soon as possible, and those that cannot be eaten should be tightly sealed or wrapped in fresh-keeping bags and put into the refrigerator for freezing.
Error 3: Take out a big bag of dumplings and thaw them. If you can’t finish eating them, plug the rest back into the refrigerator.
After many times of freezing and thawing, food is easy to breed a large number of bacteria, and nutrition will also be lost, not to mention poor taste.
The most elegant way is that frozen food can be repackaged according to the amount of food eaten each time.
If you don’t pay so much attention, please take out as much as you eat and thaw it to avoid repeated thawing.
