Question

Quizplus · Accepted Answer

The freeze-drying process is called lyophilization, which involves removing the water content of a substance by freezing it and then subjecting it to a vacuum to vaporize the ice. This process preserves microorganisms for long periods by dehydrating them and preventing the growth of bacteria or other contaminants. Desiccation is a similar process but does not involve freezing. Flash freezing is a fast freezing method used in food and biological preservation. Pasteurization is a heat treatment used to kill or reduce the number of bacteria in food, while sterilization aims to eliminate all forms of microbial life.
