The correct ways to heat milk are: heating in a microwave oven, heating directly in a pot, or soaking in hot water.

1. Microwave heating

This method is the fastest among the three methods of heating milk. It can shorten our time and improve the efficiency of our life. However, putting milk in a microwave oven can easily damage the nutrients in the milk because the temperature is too high. Therefore, if you plan to use a microwave oven to heat it, you must control the time and choose a fire that is not too big. A medium or small fire will suffice. .

At the same time, we must be careful when putting milk into the microwave. If there is no word "microwaveable" on the package, we should pour it into a special container for heating. Otherwise, improper operation can easily lead to The microwave exploded.

2. Put it directly into the pot and heat it

This method is the most common and most common method. We pour the milk into the pot. At this time, you may wait for it to boil before stirring, but we will find that the milk heated by this method will often stick to the pot, and the nutrients of the milk will be reduced.

This is wrong. The most correct way is to pour the milk into a clean pot and turn off the heat immediately after the first bubbles appear. Use tools to stir, stir slowly, heat it two to three times in this way, and then pour the milk out.

3. Hot water immersion heating

This method is very friendly to student parties. We only need to put the milk with pure milk into a container, and then put Pour boiling water in and completely submerge the milk. After soaking for five to ten minutes, the milk will become warm. Take out the milk and insert the straw into it, then you can drink it. This method is my favorite way to heat milk.

Milk purchase guide:

1. Room temperature milk

Ultra-high temperature instant sterilized milk (that is, milk stored at room temperature) is mainly sold on the market. . When purchasing, in addition to going to a qualified large market, you should also check whether the packaging is intact, whether the label content is complete, and pay special attention to the shelf life. Pinch the texture of the packaging. If it feels hard, it may have deteriorated.

2. Freshness

Fresh milk is a uniform colloidal fluid that is milky white or slightly yellow, with no precipitation, no clots, no impurities, no stickiness, and no peculiar smell. Fresh milk contains sugars and volatile fatty acids, giving it a slightly sweet taste and a refreshing and pure milky aroma. Pour the milk into the cup and shake it. The milk will easily stick to the wall. Drop a drop of milk on the glass. The drop will be round and difficult to spread. No coagulation or floc when boiled.

If the milk is thin, whitish, has a reduced fragrance, and is not easy to hang on the wall; or if it drips on a glass piece and the milk droplets are not formed and spread easily, it is milk mixed with water. If after boiling and cooling slightly, tofu-like condensation or floc appears on the surface, it indicates that the milk is not fresh or has deteriorated.
