Many friends like to save all the food to the refrigerator, and save very casual, in fact, the refrigerator food preservation also pay attention to certain methods, we will look at the specific laws of the refrigerator preservation.
Fresh box - health and environmental protection
Use different sizes of fresh boxes to save the food in the refrigerator separately. If there is leftover food, it is best to use sealed boxes for separate storage to avoid odor and to ensure the taste of the food. In general, cling boxes are better than cling film because they can be used multiple times, are environmentally friendly and are convenient.
Vegetable storage - different vegetables have different shelf life
Spinach, celery and other leafy greens should be dried and wrapped in a paper bag and stored in the refrigerator because the paper can absorb the moisture on the leaves and prevent the vegetables from deteriorating. Green leafy vegetables washed and controlled dry, put into a fresh bag or fresh box, can be stored for up to 2 days. Lettuce, celery, etc. do not wash, directly wrapped in plastic wrap, can be stored for 3 days.
Note: Some vegetables are not suitable for refrigerator storage, such as tomatoes, cucumbers, etc.. This is because temperatures below 4 degrees can cause losses to their nutritional structure. If you have to store them, also try to eat them within 24 hours.
Storage by temperature - cooked food zoning insurance
The inner side door of the refrigerator has the highest temperature, so it is suitable for storing bottled food, such as vegetable and fruit juices, mineral water, peanut butter, salad dressing, chili sauce, etc. Inside the freezer, the area with the lowest temperature is the deepest part of the topmost compartment. This area is suitable for storing cooked meat, ham, and dairy products, etc.
Storage of leftovers - meat dishes are allowed and vegetarian dishes are not
It is worth reminding that try to eat all the vegetables for each meal and leave some of the meat dishes. Because meat dishes will lose some vitamins when stored for 2 days, but proteins can be retained and no harmful substances will be produced. Vegetables, on the other hand, tend to produce nitrites in storage, so it is not recommended to eat them again. Among the leftover meat dishes, give priority to eating aquatic products because they are more likely to breed harmful microorganisms. Leftovers must be discarded after repeatedly heating them twice.
Zero freshness - Keeping food fresh
A three-door refrigerator with a dedicated zero-degree storage area is a good choice. Fish, shrimp, crab and other seafood food can be placed in this area. The food stored at this temperature does not lose nutrition and also reduces the loss of taste after the food is frozen and frozen below zero degrees. It should be reminded that in order not to affect the taste and nutrition of the food, the food in the zero degree storage area is best eaten within 72 hours.
Meat preservation: store in small pieces and avoid repeated freezing
Tenderloins should be cut into small pieces and frozen separately. This is convenient for flexible storage on the one hand, and also to avoid repeated freezing. Once thawed, the damaged tissue cells will ooze out a lot of proteins, which will become nutrients for bacteria to reproduce. So once thawed meat should be processed as soon as possible to eat. If repeatedly frozen or stored for too long, the vitality of certain bacteria and enzymes will be restored, causing protein deterioration, and can also produce toxic histamine substances, eaten may occur food poisoning.
Fish refrigeration - one month freshness period
The fish in the refrigerator should not be stored for too long, home refrigerator refrigeration temperature is generally -15 ℃, the best refrigerator can only reach -20 ℃, and aquatic products, especially fish, in the storage temperature does not reach -30 ℃ below, the fish tissue will be dehydrated and other changes, such as crucian carp long time refrigeration, it is easy to appear fish body sour, meat quality changes, inedible. Therefore, the fish stored in the refrigerator should not be too long, it is best to finish it within a month.
Zero degree freshness rule - eat up within 72 hours
Zero degree is the best temperature to ensure the freshness of food. Therefore, there is zero degree special storage area of the three door refrigerator is a good choice. Fish, shrimp, crab and other seafood food can be placed in this area. The food stored at this temperature does not lose nutrition and also reduces the loss of taste after the food is frozen and frozen below zero degrees.
