Due to the fact the standard way of preservation consists of employing substantial temperatures to evaporate liquids, lyophilization is perfectly-fitted to any product that may be delicate to warmth—from foodstuff to biopharmaceuticals, which includes Organic medicine. Lyophilization depends on a three-action process that includes sublimation, which allows ice to change from the stable to some vapor devoid of passing by way of a liquid phase and can assist maintain the viability of Organic drugs.
