1, the quality has declined.
Imported milk has to be transported for a long time and passed various tests. It takes two or three months to enter the domestic market from abroad. If the shelf life is too short to meet the market demand, it is generally required to have a longer shelf life. Although the shelf life is very long, due to the pursuit of shelf life, the quality of imported milk will decline, and the nutritional value of imported milk will also decline.
2. Reasons for long shelf life
The shelf life of imported milk is longer, because sterilization is adopted, and heating sterilization takes longer. Generally, there are two sterilization methods, one is pasteurization and the other is ultra-high temperature sterilization. Besides proper sterilization, packaging is also closely related to better sealing. Strict packaging can extend the shelf life of milk to one year, which is generally unrelated to food additives.
3. Can I drink imported milk?
Some people think that the shelf life of imported milk is so long because it reduces the quality. Is it still drinkable? Actually, it is possible. The quality standards of imported milk are different from those in China, and some production processes are more stringent. You can still choose imported milk, but be careful not to choose a large number of imported milk that is about to expire to avoid deterioration.
