Heating leftovers

Busy modern people eat out most of the time, and leftovers are inevitable. Today we will teach you how to pack and heat leftovers scientifically. Knowledge of packaging leftovers: 1. Packaged food needs to be cooled thoroughly before it is put into the refrigerator. This is because hot food suddenly enters the low temperature environment, and the food center is prone to qualitative change. Moreover, the hot gas brought in by the food will cause condensation of water vapor, which will promote the growth of mold, resulting in the mildew of the whole food in the refrigerator. 2. The packaged food stored in the refrigerator must be returned to the pot before eating. This is because the temperature of the refrigerator can only inhibit the growth of bacteria, not completely kill them. If you don't heat it before eating, it can cause discomfort after eating, such as diarrhea or diarrhea. 3. The storage time of leftovers should not be too long. The storage time of leftovers should not be separated from meals. The leftovers in the morning should be eaten at noon, and the leftovers at noon should be eaten in the evening. It is best to eat them in 5-6 hours. Because under normal circumstances, through the high temperature of 100 degrees Celsius heating, a few minutes can kill some bacteria, viruses and parasites. However, if the food is stored for a long time, the bacteria in the food will release chemical toxins, which can not be heated. 4. Vegetables should not be packed, because in the process of making vegetables, salt is generally less used. When the vegetables are put down for a long time at a relatively high temperature, the bacteria in the vegetables will multiply in large numbers, and the nitrate will be reduced to nitrite under the action of bacteria. Nitrite is easy to synthesize nitrosamine with amine in nature. Nitrosamine is a strong carcinogen. If we eat leftover vegetables for a long time, it is not good for our health. For example, if we eat salted vegetables for a long time, we will have a higher risk of gastric cancer. It's important to deal with the leftovers. Of course, it is best not to leftovers, according to the amount of rice under the pot. If it is left, the leftovers should be loose and put in a well ventilated, cool and clean place to avoid pollution Don't eat leftovers. After a long time of salting, the salt on the surface of the leftover vegetables will turn into nitrite when heated repeatedly, which is the most likely to cause poisoning Packing leftovers is harmful. Fish: just heat for four or five minutes. The bacteria in the processed fish are easy to reproduce. The Escherichia coli on it can multiply twice every eight minutes at about 20 degrees centigrade. Within five or six hours, one bacteria will become 100 million. That's enough to make your stomach uncomfortable. So, the packaged fish must be heated for four or five minutes. However, if the fish is heated for a long time, the nutrients beneficial to human nervous system, such as total protein, fish fat and rich vitamins, will lose their nutritional value. 2. Meat: Please add vinegar when heating meat and animal food should be packaged and reheated, preferably with some vinegar. Because this kind of food is rich in minerals, these minerals will overflow with water after heating. Then, add some vinegar when heating, these substances will be synthesized into calcium acetate when meeting with acetic acid, which not only improves its nutrition, but also benefits our body's absorption and utilization. 3. Seafood: when heating, you should add some seasonings shellfish. When heating seafood, you'd better add some wine, onion, ginger and other seasonings, which can not only improve the freshness, but also have a certain bactericidal effect. It can kill the latent Vibrio parahaemolyticus and prevent gastrointestinal discomfort. Especially ginger has the function of sterilization and detoxification (especially the poison of fish, shrimp and crab) in traditional Chinese medicine effect. 4. Starch: please finish it within 4 hours some foods rich in starch should be finished within 4 hours, because they are easy to be parasitized by Staphylococcus. And the toxin of this kind of bacteria will not be decomposed under high temperature heating, which can not solve the problem of deterioration. So, if you haven't finished eating in a short time, don't eat any more even if it doesn't go bad in appearance.

How to deal with it

The table of Spring Festival is always full of fish and dishes. The elderly, in particular, are always afraid that the food is not rich enough and that the children are not enough to eat. They have to make new dishes for almost every meal. After being exhausted by the delicious food, the refrigerator is also filled with all kinds of leftovers. In the end, it's often the children who leave, the old couple eat leftovers, have no appetite, and even have abnormal health indicators. So, how do we leave the leftovers? And how do we deal with them? If we want to have a good time in the new year, it's hard not to leave the leftovers. Since we have left the leftovers, we have to find a way to finish them in order not to waste them too much. If you are still having a headache about how to deal with leftovers, you might as well listen to the four tips for dealing with leftovers during the Spring Festival. The meat dishes in the refrigerator can be preserved for 1-2 days as long as they are thoroughly heated before eating. Although some B vitamins will be lost, the protein can be completely preserved and no harmful substances will be produced. However, vegetables are easy to produce nitrite during storage, and the antioxidant components, vitamin C and folic acid are seriously lost after storage and repeated heating. Moreover, meat dishes still taste good when reheated, and vegetables almost lose their delicious value after reheating. Therefore, in one meal, we should call on everyone to concentrate on eating vegetables as much as possible, while meat dishes can be reserved for the next meal. among meat dishes, aquatic products should be eaten first, because the protein of aquatic products is particularly easy to be decomposed by microorganisms, and aquatic products are more likely to breed harmful microorganisms. Due to the large number and variety of Spring Festival leftovers, it is often impossible to effectively use the space of the refrigerator to store leftovers with plates. It is suggested to prepare some small square and rectangular fresh-keeping boxes in advance, put the leftovers into the fresh-keeping boxes by classification, and then arrange them in the refrigerator neatly. The storage location of leftovers is also important. The most perishable foods, such as bean products and seafood, should be placed deep in the lower layer of the freezer or in the fresh-keeping drawer, because the temperature here is lower; fried fish and fried meatballs with lower moisture content can be placed in the slightly outer part; the remaining juice can be placed in the refrigerator door, because the juice is sour, and bacteria are not easy to reproduce rapidly. coup 3 bring creativity into play, renovate the old ones, and eat leftovers for the new year. It's not very good psychologically, but if leftovers are turned into new ones, the feeling will be very different. In fact, for many meat dishes, it's not difficult to turn leftovers into new ones. For example, if you add curry powder, onion, mushroom, potato and carrot to the leftover braised spare ribs, it will be very popular to make curry onion fried spare ribs. The same is true for the leftover fried diced meat and sliced meat. Eat the vegetables first, and then mix the meat with the newly fried vegetables. if you have a large piece of meat with bone, you can cook it into soup with kelp, mushroom, radish, green vegetables, etc.; if you have a large piece of meat without bone, you can crush it, such as tearing chicken into shredded chicken, slicing soy sauce meat into shredded meat, and then mix it with cold vegetables, or use it as raw materials for pies and spring rolls. if you have stewed prawns in oil, just remove the oil and stir fry some ketchup to transform them into tomato prawns. Squid, shrimps and other river delicacies and seafood can be used as ingredients for soup or noodle soup. Changing leftovers into new dishes is actually adding fresh vegetables instead of meat dishes, which is conducive to nutrition balance. if rice is left, it will be easier. With black sesame, red dates, oats, lotus seeds and so on, the porridge will taste good and healthy. During the Spring Festival, new dishes may turn into leftovers at every meal, while old dishes may still be left after renovation. Therefore, if we do not control the total amount of dishes in a meal, leftovers are always inevitable and will gradually accumulate. Therefore, we should try our best to control the number of dishes in each meal. On the premise of not having a large number of leftovers, we should launch new vegetables in each meal and renovate old dishes in a planned way. when there are many leftovers, it is impossible to renovate all of them in one meal. Therefore, two kinds of renovated dishes can be served in the order of aquatic products first, meat first, light dishes first, and strong dishes second, and these renovated dishes are no longer left. It's the same way to eliminate leftover dumplings. If there are more leftover dumplings, it's not necessary to heat them all. Instead, according to the amount of food eaten by the family, take some of them or roast or fry them, and finish the whole meal. The rest are put in the deep of the refrigerator, and let them wait for another day at low temperature. In this way, the food can be prevented from being heated repeatedly. Although the above four tips will help to store and handle spring festival leftovers, after all, leftovers are not as good as new ones. If we can arrange the amount of food reasonably during the festival, we won't let ourselves fall into the trouble that leftovers fill the refrigerator. I would also like to remind you that you must not force yourself to eat too much because you are afraid of wasting leftovers, because once these excess foods enter our body, they will bring a lot of garbage and heavy burden, not to mention pancreatitis, bacterial food poisoning, gastrointestinal diseases, etc. It's not worth it to raise blood sugar, blood lipid and blood pressure, even if they only become fat accumulation in the body It's also a great pity. In addition, if the leftovers have been heated repeatedly for two days, it is recommended to discard them. After all, health is the first.
