Title:
PROCESS FOR PRODUCTION OF GALACTOMANNAN WITH REDUCED MOLECULR WEIGHT AND CATALYST TO BE USED THEREIN
Document Type and Number:
WIPO Patent Application WO/2011/013530
Kind Code:
A1
Abstract:
Provided is a process by which galactomannan as a substrate can be partially hydrolyzed in a higher concentration, in fewer operation steps and in a shorter time in comparison to conventional processes, and by which a partial hydrolyzate having a molecular structure that achieves a freezing-denaturation inhibitory effect or a stabilizing effect can be efficiently produced. The process comprises a step of subjecting a galactomannan to hydrothermal reaction under such pressure and temperature conditions that neither water nor the galactomannan boils to thereby selectively cleave β-1,4 bonds of the linear backbone chain of the galactomannan and thus partially hydrolyze the galactomannan, the linear backbone chain comprising D-mannose units.
