Working principle:

Freeze drying or lyophilization is a highly successful method for preserving bacteria, yeast & the spore of filamentous fungi. During the drying process, water is extracted from frozen material by avoiding the liquid state through sublimation i.e. direct conversion from ice to vapor. This happens under vacuum and the temperature in the product is normally less than -10 °C. Through freeze drying the microorganisms mainly bacteria and fungi are transformed into a dry product. During this process enzymatic and chemical changes are largely avoided. Freeze drying prevents shrinkage, structural change and help to retain viability for about 15 – 20 years based on the storage conditions.
