Testing of alkene cream, cream, anhydrous cream/food products

Cream is the fatty part of milk, which is an O/W type emulsion obtained by separating skimmed milk from milk. 1. The collection, filtration, and preheating of raw milk are basically the same as other milk processing. 2. Separation: A separator is used for separation. After the separator is started, the preheated milk can only be fed into the separator after the separation bowl reaches the specified speed. 3. Standardization: According to China's food hygiene standards, the fat content of sterilized milk is 3.0%, and those who do not meet the standards will be standardized. 4. Cooling and storage: When the cream cannot be processed immediately, it must be immediately cooled, that is, cooled while separating. Alternatively, the two-stage method can be used: first cool to around 10 ℃, and then cool to the desired temperature. 5. Sterilization: Use the retention sterilization method, with a heating rate controlled at 2.5-3 ℃ per minute. The sterilization temperature is 72 ℃ for 15 minutes; 77 ℃, 5 minutes; 82-85 ℃ for 30 seconds; 116 ℃ for 3-5 seconds. 6. Cooling and homogenization: After sterilization, cool to 5 ℃. Homogenization once again can increase viscosity, maintain a good taste, improve the thermal stability of the cream, and avoid flocculent precipitation when the cream is added to coffee. The homogenization temperature is 45-60 ℃ (depending on the quality of the cream), and the homogenization pressure is 8000-18000 kPa. 7. Physical maturation: The homogenized cream should be quickly cooled to 2-5 ℃, and then held at this temperature for 12-24 hours for physical maturation, allowing the fat to change from liquid to solid (fat crystallization). 8. Cooling and packaging of cream: After physical maturity, cool to 2-5 ℃ before packaging, and store at 5 ℃ for 24 hours before leaving the factory. The packaging specifications include 15, 50, 125, 250, 500, 1000 milliliters, etc. Developed countries use more flexible packaging
