If you choose an open flame when heating milk, you should use a high-fire method to heat it quickly. If you choose to heat it over water, it is best to use a porcelain cup, because stainless steel quilts conduct heat too quickly and are cold. Faster, when the water temperature reaches 60 or 70 degrees, soak it for five minutes and it will be warm.

1. Heating over an open flame

When heating on a gas stove, you need to use a high-fire method of rapid cooking, just like stir-frying vegetables, which can lock in the nutrients and prevent them from being lost. Slow cooking will only destroy the vitamins, proteins and other nutrients in the milk.

2. Heating in a microwave oven

Heating in a microwave oven, the heating time should not be too long. Generally, set the heat to medium-low and heat 250 ml for about 1 minute, otherwise the nutrients will be destroyed. But be aware that the temperature will be uneven when heated in a microwave oven. Remember to stir it before drinking. Also note that when heating milk in a microwave oven, it is best to pour the boxed or bagged milk into a container that can be used for microwave heating and then heat it. It is best not to heat it directly with a bag or box.

3. Heating over water

The best way to warm milk is to heat over water, that is, pour the milk into a container such as a cup, and then put it into hot water to warm it. There is no need to heat the water when it is hot or lukewarm, and the temperature can be adjusted according to personal taste. Although this method is more troublesome, it can avoid the loss of nutrients when heated in a microwave oven and boiled in a pot.

Note: If it is fresh milk squeezed directly from cows, it must be sterilized, such as heating it to 100°C and boiling it for a while, and then drinking it after sterilization.

4. It is best to choose porcelain cups for water-proof heating.

It is generally recommended to choose high-necked cups or bottles instead of stainless steel cups, because stainless steel cups have poor thermal conductivity. It's very strong, it heats up quickly, and it cools down quickly. The water in the cup is higher than that of bagged milk or boxed milk, so that it can be heated evenly. The milk must be placed correctly in the water and cannot be placed upside down, because the normal top of the milk has a small hole in the tin foil, so it is easier to put it upside down. Leakage due to soaking in hot water.

5. Time selection for water heating

Boil the water first, and when it cools to 60-70 degrees, you can warm the milk. Generally, the soaking time is 5 minutes. After about 10 minutes, the milk is already warm. If you want it to be warmer, you can soak it longer, or you can change it to a cup of hot water and continue soaking. The time and heat can be determined according to your own preferences.
