How to Make Leftovers Delicious During the Holidays
After an era of extravagance, the consciousness of frugality is increasingly ingrained in people's minds. When dining out, people no longer order a huge table of food and leave half uneaten, feeling too embarrassed to take it home for fear of being laughed at. Nowadays, the good habit of taking home leftovers is becoming more and more popular. But have you ever thought about how to better utilize the nutritional value of the packed food when you get home?
How to Reheat Leftovers Harmlessly
The Art of Packing:
1. Packaged food should be cooled completely before being put in the refrigerator
This is because when hot food suddenly enters a low-temperature environment, the center of the food is prone to spoilage. Moreover, the heat brought by the food will cause water vapor to condense, promoting the growth of mold, which can lead to the spoilage of all food in the refrigerator.
2. Packaged food must be reheated
Food stored in the refrigerator must be reheated after being taken out. This is because the temperature of the refrigerator can only inhibit bacterial growth, not kill them completely. If you do not heat the food before eating, it may cause discomfort, such as dysentery or diarrhea.
3. The storage time of leftovers should not be too long
The storage time for leftovers should preferably not span more than one meal. Leftovers from breakfast should be eaten at noon, and leftovers from lunch should be eaten at dinner. It is best to finish them within 5-6 hours. This is because, under normal circumstances, certain bacteria, viruses, and parasites can be killed within minutes by heating to 100°C. However, if the food is stored for too long, bacteria in the food will release chemical toxins, which cannot be neutralized by heating.
4. Vegetarian dishes are not suitable for packing
In the process of making vegetarian dishes, salt is generally used in smaller amounts. When vegetarian dishes that have been prepared are left in a relatively warm environment for a long time, bacteria in the dishes will multiply rapidly. Nitrates are reduced to nitrites by bacteria. Nitrites can easily react with amines in nature to form nitrosamines, which are potent carcinogens. If we eat leftover vegetables for a long time, it is not good for our health. For example, the risk of developing stomach cancer is higher for those who often eat pickled foods like pickles.
Now, let's talk about the things to pay attention to when reheating different types of leftovers:
Fish: Heat for 4-5 minutes
Bacteria in processed fish dishes multiply easily. The E. coli on them can double every 8 minutes at a temperature of around 20°C, and within 5-6 hours, one bacterium can become one hundred million. Such a number is enough to make your stomach uncomfortable. Therefore, packed fish must be heated for 4-5 minutes. However, if heated for too long, the high-quality protein, fish oil, and rich vitamins in the fish, which are beneficial to the human nervous system, will lose their nutritional value.
Meat: Add some vinegar when heating
When reheating meat and animal-based foods after taking them home, it is best to add some vinegar. This is because these foods contain relatively rich minerals. When heated, these minerals will be lost along with the moisture. Therefore, adding some vinegar during heating will cause these substances to combine with acetic acid to form calcium acetate, which not only improves their nutritional value but also facilitates the body's absorption and utilization.
Seafood: Add some seasoning when heating
When heating shellfish and seafood, it is best to add some wine, scallions, ginger, and other seasonings. This can not only enhance the flavor but also has a certain bactericidal effect, killing the latent *Vibrio parahaemolyticus* to prevent gastrointestinal discomfort. Ginger, in particular, has the effect of sterilizing and detoxifying (especially the toxins from fish, shrimp, and crabs) in traditional Chinese medicine.
Starchy foods: Eat within 4 hours
Starchy foods that are brought back as leftovers should be eaten within 4 hours because they are easily parasitized by *Staphylococcus*. The toxins produced by this type of bacteria are not broken down by high-temperature heating, so the problem of spoilage cannot be solved. Therefore, if you haven't finished them in a short time, do not eat them even if they don't look spoiled on the outside.
