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 ] UHT is most commonly used in milk production, but the process ...

Confit, as a cooking term, describes when food is cooked in grease or oil at a lower temperature, as opposed to deep frying. While deep frying typically takes place at temperatures of 160–230 °C (325–450 °F), confit preparations are done at a much lower temperature, such as an oil temperature of around 90 °C (200 °F), or sometimes even ...

Dehydration has been used widely for this purpose since ancient times; the earliest known practice is 12,000 B.C. by inhabitants of the modern Middle East and Asia ...
