Preserving food by lowering its temperature below 0°C so that water in the food turns to ice, which stops most microbial growth.
Frozen peas, frozen paneer, and frozen parathas sold in supermarket freezers all rely on simple freezing to stay safe for months.
A fast-freezing method where small food pieces are frozen separately before packing, so they do not stick together into one solid block.
Dehydration by freezing the food and subliming the ice under vacuum below the triple point of water, followed by desorption of bound water.
An unbroken chain of refrigerated storage and transport that keeps a food cold from the time it is produced until it reaches the customer.
