which method of microbian control does not rely on denaturing proteins and/or disrupting the integreity of the cell membrane
Over [174]

Lyophilization Methods of microbial control do not rely on protein denaturation and/or disruption of cell membrane integrity

Lyophilization Freeze-drying or freeze-drying is the process of freezing the product and placing it under vacuum, then removing the water from the product, allowing the ice cream to go directly from solid to vapor without going through a liquid phase. Freeze-drying is a water removal process commonly used to preserve perishable materials, extend shelf life, or make materials easier to transport. Freeze-drying is to sublime the frozen water in the material by lowering the pressure and applying heat after freezing the material. Lyophilization converts pharmaceuticals into stable solids by removing water from liquids
