Products made primarily from fresh cow (or sheep) milk and its derivatives. These include: Liquid milk products (pasteurized milk, sterilized milk, yogurt, formula milk); milk powder products (whole milk powder, skim milk powder, sweetened whole milk powder and flavored milk powder, infant formula, other formula milk powder); condensed milk products (whole unsalted condensed milk, sweetened whole milk powder, flavored/modified condensed milk, formula condensed milk); milk fat products (whipping cream, butter, anhydrous butter); cheese products (raw cheese, processed cheese); and other dairy products (casein, lactose, whey powder, etc.).
Pasteurized milk is a liquid product made from fresh cow (or sheep) milk through pasteurization. While pasteurization preserves most of the proteins and vitamins in the fresh milk, it does not kill all microorganisms. Therefore, pasteurized milk cannot be stored at room temperature and must be refrigerated. Its shelf life is 2-15 days.
Yogurt is a product made primarily from fresh cow (or sheep) milk or reconstituted milk, with or without added ingredients, fermented using *Lactobacillus bulgaricus* and *Streptococcus thermophilus* strains. Based on the raw materials used, it is divided into: pure yogurt, flavored yogurt, and fruit yogurt; based on fat content, it is divided into: whole milk, partially skimmed milk, and skimmed milk, etc.
It includes: liquid milk (pasteurized milk, sterilized milk, yogurt, formula milk); milk powder (whole milk powder, skimmed milk powder, sweetened whole milk powder and flavored milk powder, infant formula milk powder, other formula milk powder); condensed milk (unsweetened whole milk condensed milk, sweetened whole milk condensed milk, flavored/modified condensed milk, formula condensed milk); milk fat (light cream, butter, anhydrous butter); cheese (raw cheese, processed cheese); and other dairy products (casein, lactose, whey powder, etc.).
Pasteurized milk: A product made from raw milk that has undergone pasteurization. While pasteurization preserves most of the proteins and vitamins in the raw milk, it does not kill all microorganisms. Pasteurized milk requires strict storage conditions and must be refrigerated. Its shelf life is 1-3 days.
Used milk: A sterile product made from raw milk that has undergone ultra-high temperature (UHT) sterilization followed by aseptic packaging or secondary sterilization after packaging. All microorganisms in the raw milk are killed. Used milk does not require refrigeration and has a shelf life of several months at room temperature.
Formula milk powder: A dairy product made from raw milk or milk powder, processed and dried to meet the nutritional needs of different populations. It involves removing some nutrients or fortifying certain nutrients (or both). Types of formula milk powder include infant formula, senior milk powder, and other milk powders for special populations, such as Taizile infant formula.
Cheese: A product made from milk, cream, partially skimmed milk, or mixtures of these products, through sterilization, curdling, and whey separation.
Casein: A product made from skimmed milk, through the formation of casein coagulation under the action of enzymes or acids, followed by washing, dehydration, pulverization, and drying.
