Low molecular weight treatment galactomannan, method for producing galactomannan, food material freezing denaturation inhibitor, food or food material and food or food material freezing denaturation prevention method.

摘要

PPROBLEM TO BE SOLVED: To provide a substance which exhibits a remarkable effect on denaturation by refrigeration of a protein by adding a minute amount of the substance in preserving a food or a food material by refrigeration, its manufacturing method, and a method of preventing denaturation by refrigeration utilizing this substance. PSOLUTION: Galactomannan is subjected to low-molecularization treatment by microorganisms or an enzyme to manufacture low-molecularization-treated galactomannan having a specific molecular structure. By adding this low-molecularization-treated galactomannan to a food or a food material, the denaturation by refrigeration of the substance added therewith can be prevented.
