Lyophilized products are manufactured using ‘Lyophilization’ which is an effective way of drying micro-organisms without harming them. It makes use of the physical phenomenon of sublimation, which involves the direct transition between the solid state and the gaseous state without passing through the liquid phase. To achieve this, the frozen product is dried under vacuum, without being allowed to thaw out. The process is most suitable for a wide range of processing Bio products for preserving the characteristics identical of the initial substance or organisms.
