Lyophilization

Lyophilization, also known as freeze-drying, is a process used to preserve materials like medicines or food. It involves freezing the product, then removing the ice directly from solid to vapor under low pressure. This carefully controlled process reduces water content, preventing decay and extending shelf life while maintaining the product’s structure and effectiveness. When needed, the product can be rehydrated quickly, making lyophilization ideal for sensitive substances that require preservation without heat damage.
