Milk is a fresh product and should be drunk as fresh as possible. Generally speaking, milk can be divided into two categories. One is sterilized milk, which is suitable for storage at room temperature, and the validity period is about one month to half a year. The other is low-temperature milk, also called pasteurized milk, which has the best storage effect at around 4℃-6℃ and cannot be stored at room temperature. Researchers told reporters that frozen storage of milk is also possible, but in the frozen state, the fat in milk is separated from protein, the taste is obviously weakened, and the nutrients are not easily absorbed. The researchers suggested that milk should be stored in the cold storage below 10℃.

As for beer, according to the research of beer experts, the most suitable drinking temperature of beer is 8- 15℃. If the temperature is too high, it will be rough to drink, and the miscellaneous taste of beer will be easily exposed, while if the temperature is too low, the taste will be uncomfortable and the mouth will feel frozen. Especially when beer is frozen below 3℃, the flavor of beer will change and it is difficult to foam.

More importantly, the volume of beer will increase after freezing, which will easily lead to the rupture of the bottle, so don't put the beer in the freezer. Here, I also want to remind everyone that it is not advisable to eat pickled and smoked food at the same time, do not drink strong liquor, do not drink beer after sweating, and do not drink old beer.

In some cold places, cabbage is easily frozen if it is not stored properly. Is this frozen cabbage edible? Is it harmful to human body? The nutritionist told us that frozen rotten cabbage can't be eaten, otherwise it will cause poisoning. Because the nitrate contained in rotten Chinese cabbage turns into toxic nitrite, it can turn low-iron hemoglobin in blood into methemoglobin, which leads to the loss of oxygen carrying capacity of blood, so that people will be poisoned by hypoxia.

Under normal circumstances, although the outer leaves of Chinese cabbage are frozen at -2C, if properly managed, they can be thawed slowly and restored to a fresh state. When the temperature is too low, the protoplast of Chinese cabbage is destroyed, cells die, and water rot will occur when thawed at high temperature.

Radish loses its nutrition after freezing. It is recommended not to fry food. You might as well stew it. It goes with other foods. These radishes are thawed in cold water, washed and diced, and pickled with soy sauce and other seasonings to make pickles. You can also add onions, parsley, soybeans, peppers and wild vegetables. Anyway, they are delicious. Remind everyone that we must master the heat (cooked first, cooked first), and finally cool it, store it in a jar and prepare to take it out!

Frozen Citrus Eating frozen citrus is easy to be poisoned. Eating too much bitter immature citrus can also be harmful to health. So don't eat.
