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]
Ultra-high-temperature ceramics (UHTCs) are a type of refractory ceramics that can withstand extremely high temperatures without degrading, often above 2,000 °C. [1] They also often have high thermal conductivities and are highly resistant to thermal shock, meaning they can withstand sudden and extreme changes in temperature without cracking or breaking.
Scalability of the process is therefore limited by the ability of these special furnaces with mechanical pressing to exert and control high forces over large areas uniformly at very high temperature (usually graphite pistons and molds). The choice of process depends on the desired material properties, cost constraints, and production scale.
The list includes technologies that were first posited in non-fiction works before their appearance in science fiction and subsequent invention, such as ion thruster. To avoid repetitions, the list excludes film adaptations of prior literature containing the same predictions, such as " The Minority Report ".
Aseptic processing works by placing sterilized food (typically by heat, see ultra-high temperature processing) into sterlized packaging material under sterile conditions. The result is a sealed, sterile food product similar to canned food, but depending on the technique used, damage to food quality is typically reduced compared to canned food.
All of the films include core elements of science fiction, but can cross into other genres such as drama, mystery, action, horror, fantasy, and comedy. Among the listed movies are films that have won motion-picture and science fiction awards as well as films that have been listed among the worst movies ever made , or have won one or more Golden ...
UHT is ultra-high-temperature processing (or ultra heat treatment), used to sterilize milk. UHT or Uht may also refer to: Unhextrium, chemical element 163, symbol Uht; Ultra-high-temperature metamorphism in geology; United Hebrew Trades, New York, US, 1880s; Unterstützungshubschrauber Tiger, a variant of Eurocopter Tiger
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 ...
