Explanation:
Detailed explanation-1: -Freeze-drying is a desirable way of preserving food since it takes place at very low temperatures (commonly around 14°F to-13°F [-10°C to-25°C]) at which chemical reactions take place very slowly and pathogens survive only poorly.
Detailed explanation-2: -a) Cryobiology is the branch of biology that studies the preservation of life at low temperature. The low temperature deactivates the enzymes which increases the shelf life and helps in preservation.
