Lyophilization

Meaning

A sophisticated industrial and pharmaceutical process, also known as freeze-drying, used to preserve highly sensitive biological materials, including peptides and certain hormones. This technique involves freezing the substance and then reducing the surrounding pressure to allow the frozen water to sublimate directly from solid ice to water vapor. Lyophilization effectively removes water while maintaining the product’s chemical structure and biological activity, extending its shelf life significantly. This preservation method is essential for distributing temperature-sensitive medications globally.
