Many people say that the summer dishes can't be eaten overnight, they should be poured out, or put in the refrigerator. Can they really eat them? Pouring them out is really a waste. Teach you some tips for keeping leftovers fresh!
First, we should divide the leftovers into two categories: vegetables, fish, meat and bean products.
Storage conditions of leftovers and meat
No matter what kind of food, the longer it is placed at room temperature, the later it is placed in the refrigerator, the greater the 'base number' of microorganisms, and the less safe it will be after storage.
Entering the refrigerator, the speed of cooling is also important. If the refrigerator is too full, the refrigeration effect is not enough, or the size of the dishes is too large, and the speed of air-conditioning input is slow, put it
It's hard to reduce the temperature of the food for a long time, which will also bring security risks.
1. Fish, meat and bean products - be careful of poisonous microorganisms
Fish, meat and bean products only have the problem of microbial reproduction, and the problem of nitrite basically does not need to be considered.
Fish, meat and bean products are more prone to corruption. Their common problem is the possibility of breeding dangerous pathogens, such as the dreaded Clostridium botulinum. The bacteria can produce the world's first toxin, botulinum toxin, 10000 times more toxic than potassium cyanide. The toxin can be destroyed by heating above 100 ℃ for several minutes, but it is very dangerous without heat penetration.
2. Vegetables - be careful of nitrite
It is often said that harmful substances may be produced overnight, in fact, vegetables. Because of the high level of nitrite in vegetables, it may be gradually transformed into toxic nitrite due to the activity of bacteria during storage.
However, if it is only put in the refrigerator overnight, the rise of this nitrite is far from causing food safety accidents. But in any case, vegetables are not recommended to have more than 24 hours left. You should be more careful with cold dishes.
3. Thoroughly heat
It's OK to put the leftovers in the second meal, but be sure to heat them thoroughly. The so-called thorough heating means that the whole dish is heated to 100 ℃ and kept boiling for more than 3 minutes.
Meat heating: if the meat is relatively large, it must be boiled and steamed for a long time, or the meat should be chopped and reheated.
Microwave is a good way to heat leftover food. It can make the inside of food fully heated. But in the family, it is often difficult to control the time of microwave heating, and it is easy to cause food splashing into the microwave oven. Consider using microwave oven to heat food for a minute or two, so that the internal temperature of the food rises, and then use the pot to heat it, or put the steamer on to steam, it is easier to heat through. If you don't want too much soup, you can steam or fry it.
Heating of bean products: compared with meat, bean products are more prone to corruption, so you should pay more attention to heating. It's not a pity to cook for a few minutes more, because the vitamin content in tofu is very low, and the protein, calcium and magnesium it contains are not afraid of heat, heating will not significantly reduce the nutritional value.
Heating of vegetables: vegetables are not suitable for long-term heating. You can consider steaming in a steamer. The heat transfer effect is better than heating directly in a pot, and the loss of nutrients is less.
Special reminder: we need to pay high attention to the fact that the food must not be repeatedly heated. If you know that you can't finish your second meal, heat only half of it and put the rest back in the refrigerator. Even some cooked food and bean products can be frozen directly in small boxes into the freezer.
The method of remaking leftovers
People are enthusiastic when they eat new dishes, but it's obviously unpleasant to eat the same dish at a time. In many families, housewives gain weight because they eat leftovers and lose their slim body because their husbands and children don't care about leftovers. In fact, in addition to vegetables, it is not difficult to renovate the leftovers of fish and meat food. It is nothing more than three major technologies: changing knives, adding ingredients and changing seasoning.
For example, if you have a few large pieces of meat left, you can cut them into small pieces and add some fragrant vegetables to make fried meat slices. For example, add coriander, onion, celery and so on, which can make the fried meat become fragrant and appetizing. The family will definitely welcome it as a new dish. For example, for the meat with the taste of braised pork, now we can consider adding some curry powder and some potatoes and carrots to transform it into curry flavor. You can also transform leftovers into soup, such as leftover ribs, vegetables and noodles, to make noodle soup with vegetable ribs; leftover tomato scrambled eggs, tomatoes, agaric and pimple soup, to make pimple soup with tomato flavor, etc.
In this way, the leftovers will not be wasted. When reheated, they will be cooked 'thoroughly', and the safety will be guaranteed. The family will also enjoy eating.
