AI Technical Summary
Technical Problem
Existing methods for solubilizing cellulosic biomass fail to effectively extract hemicellulose and lignin due to their different structures from cellulose, leading to the formation of precipitates and reduced yield of water-soluble components.
Method used
A method involving heating and grinding biomass raw materials with a moisture content of 50% by mass or less at 60°C to 300°C without a catalyst, followed by an extraction step to recover water-soluble components, suppressing precipitate formation and enhancing yield.
Benefits of technology
The method improves the yield of water-soluble components by preventing precipitate formation and reducing production costs, achieving efficient extraction of hemicellulose, oligosaccharides, and lignin at low temperatures.

Abstract
To provide a solubilization treatment method for a biomass raw material containing an oligosaccharide and lignin, and an extract.SOLUTION: A solubilization treatment method for a biomass raw material comprises: a heating and pulverization step 1 of heating and pulverizing a biomass raw material containing an oligosaccharide and lignin; and an extraction step 2 of adding water to a pulverized product obtained in the heating and pulverization step 1 to extract a water-soluble component from the pulverized product, wherein in the heating and pulverization step 1, a biomass raw material having a water content of 50 mass% or less is heated and pulverized under heating at a temperature of 60°C or higher but lower than 300°C without adding a catalyst.SELECTED DRAWING: Figure 1
