Pasteurized milk in Japan A 1912 Chicago Department of Health poster explains household pasteurization to mothers.. In food processing, pasteurization (also pasteurisation) is a process of food preservation in which packaged foods (e.g., milk and fruit juices) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life.
Homogenization is a mechanical treatment which results in a reduction of the size, and an increase in the number and total surface area, of fat globules in the milk. This reduces milk's tendency to form cream at the surface, and on contact with containers enhances its stability and makes it more palatable for consumers.
Milk homogenization is accomplished by mixing large amounts of harvested milk, then forcing the milk at high pressure through small holes. [7] Milk homogenization is an essential tool of the milk food industry to prevent creating various levels of flavor and fat concentration. Another application of homogenization is in soft drinks like cola ...
Ultra-pasteurization is heating the milk at a higher temperature — like 280°F for a minimum of two seconds versus regular pasteurization at 161°F for at least 15 seconds.
American raw milk. Pasteurization is a sanitation process in which milk is heated briefly to a temperature high enough to kill pathogens, followed by rapid cooling.While different times and temperatures may be used by different processors, pasteurization is most commonly achieved with heating to 161 degrees Fahrenheit (71.7 degrees Celsius) for 15 seconds.
New experiments confirm milk from H5N1-infected cows can make other animals sick — and raise questions about flash pasteurization
Pasteurization is widely used to prevent infected milk from entering the food supply. The pasteurization process was developed in 1864 by French scientist Louis Pasteur, who discovered that heating beer and wine was enough to kill most of the microorganisms that caused spoilage, preventing these beverages from turning sour. The process achieves ...
In raw milk samples spiked with high amounts of bird flu virus, small amounts of infectious virus were still detectable after treatment with a standard pasteurization method, researchers said on ...
