    Ultra-high temperature sterilized milk, also known as normal temperature milk, is mostly packed with Tetra Pak, Tetra Pak, and aseptic plastic bags. Some packages are written with "UHT" processed milk. UHT is ultra-high temperature sterilization. English abbreviation. That is, the UHT Milk Machine is used to sterilize the raw milk for 4 seconds with a high temperature of 134 ° C to 135 ° C, so that harmful bacteria and microorganisms including milk and all spores thereof are killed. Studies have shown that the ultra-high temperature sterilized milk, the Tetra Pak packaging, can be completely isolated from the outside air, so that the milk is no longer contaminated by bacteria, and can avoid further damage of nutrients caused by sunlight and oxygen. This milk has a shelf life of up to several months at room temperature, making it convenient for consumers to drink on any occasion. Completely eliminate all microorganisms in raw milk, but the higher the temperature, the greater the damage to the taste and protein of milk, so the taste and nutritional value of UHT milk is worse than that of pasteurized milk. too much.
    Pasteurized milk: The milk with short shelf life is mostly “homogeneous” milk disinfected by pasteurization. Disinfection with this method can make the nutrients in milk get better preservation. It is the current milk disinfection method in the world. one. The so-called "homogeneous" refers to the new process in milk processing, which is to pulverize the fat globules in the milk, so that the fat is fully dissolved into the protein, thereby preventing fat adhesion and coagulation, and is more conducive to human body absorption. The shelf life is generally less than 48 hours, their nutritional value is not much different from fresh milk, and the loss of B vitamins is only about 10%, but some physiologically active substances may be inactivated.
    Sterilized milk: In order to produce milk that has been stored for a long time at normal temperature, the manufacturer is fully sterilized in the processing of the Milk Production Line, and the bacteria that are beneficial to the human body are basically “smashed out”, and the nutritional components of milk are also Destroyed. This milk package is very similar to fresh milk. The shelf life is mostly 30 days or longer, and some sterilized milk has a shelf life of more than 6 months. Sterilized milk generally has a strong taste, but there is a certain loss of nutrients, and B vitamins have a loss of 20% to 30%.
