[11] [12] Currently, National Pasteurized Eggs Inc. of Lansing, Illinois, owns Dr. Cox's patent to the pasteurization process. Only National Pasteurized Eggs Inc. can provide pasteurized shell eggs produced through these patented processes. The eggs can be found in all U.S. states under the brand Davidson's Safest Choice, introduced in 2003. [13]
A Tetra Pak ultra-pasteurization line. Ultra-high temperature processing (UHT), ultra-heat treatment, or ultra-pasteurization [1] is a food processing technology that sterilizes liquid food by heating it above 140 °C (284 °F) – the temperature required to kill bacterial endospores – for two to five 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.
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.
Unit operations involve a physical change or chemical transformation such as separation, crystallization, evaporation, filtration, polymerization, isomerization, and other reactions. For example, in milk processing, the following unit operations are involved: homogenization, pasteurization, and packaging. These unit operations are connected to ...
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 bacteria that caused spoilage, preventing these beverages from turning sour. The process achieves this ...
My master’s thesis was “Effects of high pressure processing on the microbiological, physical and sensory properties of pasteurized fluid milk products.” (A riveting 101-page read for sure.)
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.
