How to heat up leftovers

Usually, if the rice cooked at home is not finished, there will be leftovers. If the rice is not spoiled, it is best not to throw it away, so as not to waste food. Leftovers can also be heated by certain methods. The best method is to steam it, so that the rice can still taste soft and sticky. In addition to the heating method of rice, after fish and meat are cold, we need to understand some correct heating methods. Let us learn about this aspect.

1. Fish: Heat for four to five minutes

The bacteria in fish are easy to reproduce. The E. coli on it will double every 8 minutes at around 20℃. In five or six hours, one bacterium will become 100 million. Therefore, packaged fish must be heated for four or five minutes. However, if the fish is heated for too long, nutrients such as complete protein, fish fat and vitamins will lose their value.

2. Meat: Add some vinegar when heating

It is best to add some vinegar when reheating meat leftovers after packing them home. Because these foods are rich in minerals, the minerals will overflow along with the water when heated. Add vinegar when heating. These substances will synthesize calcium acetate when meeting acetic acid, which not only improves the nutrition but also facilitates absorption.

3. Seafood: Add some seasoning when heating

It is best to add wine, onion, ginger and other condiments when heating seafood. This not only enhances the flavor, but also kills bacteria such as Vibrio parahaemolyticus lurking in it, and prevents gastrointestinal discomfort. Ginger, in particular, has bactericidal and detoxifying effects in traditional Chinese medicine.

4. Starch: Please finish eating within 4 hours

It is best to eat starchy foods within 4 hours after packing them because they are easily infected with staphylococci. The toxins of this type of bacteria will not be decomposed under high temperature heating, so the problem of spoilage cannot be solved. Therefore, if you have not finished eating it within a short period of time, do not eat it even if it does not appear to have gone bad.

Do not store packaged leftovers for more than 6 hours

It is best to store leftovers that you pack home and eat them within 5 to 6 hours.

Under normal circumstances, most pathogenic bacteria can be killed within a few minutes by heating at 100°C. However, if food is stored for too long, the bacteria in the food will release chemical toxins, and simple heating will be ineffective against these toxins.
