Abstract

The invention relates to a method for producing carbohydrate cleavage products, characterized by a combination of the following measures: lignocellulosic material is treated with an aqueous solution that contains hydrogen peroxide, an alcohol, in particular a C1-4 alcohol or a phenol, and a base, in order to oxidatively cleave lignocellulose and to separate the cleavage products from the material. According to the invention, a material enriched with cellulose and hemicellulose is obtained, and the material obtained, which is enriched with cellulose and hemicellulose, is treated with a carbohyrate-cleaving enzyme in order to obtain the carbohydrate cleavage products.
