The procedure involves several steps:

First, flash freezing

This is done by solidifying the foodstuffs exceptionally fast at shallow temperatures. This protects the ice from becoming gems and damaging food cells.

This is done by sublimation (conversion of heavy ice to steam) – usually using a vacuum chamber.

Finally; storage

The foodstuffs are then locked and stored in moisture and air-tight packaging and preserved for future use.
