FIELD: chemistry.
SUBSTANCE: invention relates to biotechnology. A method of lignocellulosic biomass processing is offered. Soaking a lignocellulosic biomass feedstock in steam or liquid water or a mixture thereof in the temperature range of 100 to 210°C for 1 minute to 24 hours to create a soaked biomass containing a dry content and the first liquid. Separating at least a portion of the first liquid from the soaked biomass to create the first liquid stream and the first solid stream. The first solid stream comprises the soaked biomass. Treating the first solid stream with steam to create a steam treated stream.
EFFECT: severe conditions of steam treatment ensure low concentrations of furfural in the product.
