Title:
PRODUCTION METHOD OF INDIGESTIBLE RICE, AND INDIGESTIBLE RICE
Document Type and Number:
WIPO Patent Application WO/2023/068205
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a novel production method of indigestible rice and indigestible rice. As a means for solving the problem, provided are: a production method of indigestible rice characterized by comprising a heat treatment step for subjecting raw unhulled rice to a heat treatment under one or more of the following conditions (1) to (3); indigestible rice produced through this heat treatment step; indigestible rice showing a digestion rate constant, which is evaluated by a simulated digestion test, decreased by 10% or more compared with untreated rice with no heat treatment; and indigestible rice showing a indigestible starch content increased by 50% or more compared with untreated rice with no heat treatment. (1) Exposing to a high humidity atmosphere of at least 90% RH at 60-80°C inclusive for 2-24 hours inclusive. (2) Exposing in warm water at 60-80°C inclusive for 2-24 hours inclusive. (3) Heating by microwave to 60-100°C inclusive.
