Method of inhibiting freeze concentrating of substance in wet material, method of inhibiting deactivation of physiologically active substance, and process for producing lyophilizate or frozen matter having component homogeneously diffused therein

摘要

An antifreeze protein is added to a hydrous material when the hydrous material contains water molecules and a substance other than water molecules, and freeze concentration of the substance should be inhibited; when the hydrous material contains a bioactive substance and inactivation of the bioactive substance should be inhibited; or when the hydrous material contains water molecules and a component other than the water molecules, and a frozen product or freeze-dried product in which the component is homogeneously dispersed should be produced.
