Flash pasteurization, also called "high-temperature short-time" (HTST) processing, is a method of heat pasteurization of perishable beverages like fruit and vegetable juices, beer, wine, and some dairy products such as milk. Compared with other pasteurization processes, it maintains color and flavor better, but some cheeses were found to have ...
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. [2]
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.
Pasteurization was adopted in the U.S. in the 1920s as a way to reduce foodborne illness in milk. Raw milk benefits There are a few reasons why some people prefer raw milk over pasteurized milk.
Pasteurization is a way of extending the shelf life of food by using heat to kill the harmful bacteria. We owe a big merci to the French scientist Louis Pasteur, who made this eponymous discovery ...
The studies heated raw, infected milk to the times and temperatures used for flash pasteurization — the most common form of pasteurization in the US — and found that while it greatly reduced ...
It also allowed sampling at different stages in the process. The milk goes through several heating steps before being flash-heated, and the study found the virus was inactivated even before it hit the 161-degree, 15-or-more-seconds “flash pasteurization” stage that is considered the key step in making milk safe.
Joule heating is a flash pasteurization (also called "high-temperature short-time" (HTST)) aseptic process that runs an alternating current of 50–60 Hz through food. [8] Heat is generated through the food's electrical resistance.
