Flash freezing being used for cryopreservation. Flash freezing is used in the food industry to quickly freeze perishable food items (see frozen food). In this case, food items are subjected to temperatures well below [clarification needed] the freezing point of water. Thus, smaller ice crystals are formed, causing less damage to cell membranes. [4]
As early as 1835, trichinosis was known to have been caused by a parasite, but the mechanism of infection was unclear at the time. A decade later, American scientist Joseph Leidy pinpointed undercooked meat as the primary vector for the parasite, and two decades afterward, this hypothesis was fully accepted by the scientific community.

Such parasite infections can generally be avoided by boiling, burning, preserving in salt or vinegar, or freezing overnight. Even Japanese people never eat raw salmon or ikura (salmon roe), and even if they seem raw, these foods are not raw but are frozen overnight to prevent infections from parasites, particularly anisakis.

“However, ‘flash freezing’ techniques can lead to success rates of over 90%. This is a newer method.” Arumala adds that there is currently no way to test the quality of a person’s eggs ...
Vitrification is a flash-freezing (ultra-rapid cooling) process that helps to prevent the formation of ice crystals and helps prevent cryopreservation damage. Researchers Greg Fahy and William F. Rall helped to introduce vitrification to reproductive cryopreservation in the mid-1980s. [ 23 ]
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 ...
By Thursday morning, most of these areas will go from above-freezing temperatures to temperatures in the 20s, creating what's known as a flash freeze. The temperature drop between Wednesday and ...
