Processes of producing amylase inhibitors

摘要

A process of producing an amylase inhibitor from an amylase inhibitor-containing solution extracted from wheat flour, etc with water, a dilute acid, a dilute alkali or from an amylase inhibitor-containing starch waste solution, by utilization of an adsorption of the amylase inhibitor on a calcium phosphate gel, while removing impure proteins contained in the solution. The process can produce in economy and high yields the amylase inhibitor having a very high amylase inhibitory activity but no or very little trypsin inhibitory activity.
