Fresh milk shelf life

Modern people's lives are very busy, and it is difficult to have time or opportunity to exercise. Therefore, they want to eat more nutritious food in daily life to supplement the body. Milk is the choice of many people, among which fresh milk is very familiar to everyone. So what is the shelf life of fresh milk? This is also what many people want to know. Let us take a detailed look at it below.

Now I believe everyone is very familiar with milk. Milk can not only strengthen the body, but also enhance immunity. Drinking a glass of milk before going to bed at night can help people have a good sleep. So what is the shelf life of fresh milk? Let's take a look.

As people's living standards improve and the pace of life accelerates, eating habits are also quietly changing. As one of the foods rich in nutrients, milk has been loved by more and more citizens, and the market demand is increasing day by day. The reporter recently visited the dairy products market in Maoming City and found that as the autumn and winter sales peak season approaches, the originally highly competitive dairy products market has become even more competitive, and many businesses have been focusing on the quality of milk.

The shelf life of bagged fresh milk is generally three days. Consumers should first check the production date when purchasing, try to choose milk produced on the same day, and do not buy expired milk. After purchase, fresh milk should be stored in a refrigerator at 2℃ to 6℃. Do not expose the milk to the sun or light, as sunlight and light will destroy the various vitamins in the milk. Also, do not freeze milk in the freezer of the refrigerator, otherwise the nutritional content of the milk will be reduced and the digestion and absorption rate will also be affected. Freshly squeezed milk should be consumed within 1 to 3 hours. If it is sterilized and packaged, it can be used for about 3 days, and if it is frozen, it can be used for 5 days.

The shelf life of fresh milk is relatively short, generally about 3 days. The reason why the shelf life is so short is that in order to ensure the nutritional content and freshness of milk, fresh milk is usually pasteurized. Pasteurization is currently a more advanced method for processing fresh milk. It not only preserves the nutrients in the milk, but also kills harmful bacteria in the milk, making the processed milk more delicious and pure. Below we will temporarily call it pasteurized fresh milk. Since pasteurized fresh milk takes into account both sterilization and nutrition, it only kills harmful microorganisms in fresh milk. Therefore, the shelf life of pasteurized fresh milk is relatively short and it must be stored at low temperature. The commonly used sales form is the order-and-delivery system.

There is also a type of milk that is sterilized instantly at high temperatures using UHT technology and has no preservatives added, such as Belgium's Inza whole-fat fresh milk. This has a longer shelf life and the bacteria that are easily spoiled in the milk are killed instantly at high temperatures. In China, Mengniu and Yili fresh milk are both pretty good.
