Title:
METHOD FOR PRODUCING SILICON COMPOUND AQUEOUS SOLUTION
Document Type and Number:
WIPO Patent Application WO/2023/190667
Kind Code:
A1
Abstract:
The present invention provides a method for producing a silicon compound aqueous solution etc. in a simple manner, efficiently and with low energy consumption by using a specific part of a specific plant as a raw material without using silicon dioxide as a raw material. The method for producing a silicon compound aqueous solution comprises extracting a water-soluble silicon contained in rice husks while maintaining the chemical structure of the water-soluble silicon compound, wherein the water-soluble silicon compound present in the rice husks is extracted into water with water at a temperature of 20-180°C (inclusive) after treating the rice husks in the presence of a cuticle-degrading enzyme that destroys the cuticle layer of the rice husks or while treating the rice husks in the presence of the enzyme.
