In one aspect, the present invention provides methods for preparing a fermentation product. The methods include pre-treating a mixture of biomass and ionic liquid, wherein the ionic liquid comprises a choline cation and the biomass comprises polysaccharide and lignin. The methods further include forming hydrolysates from the introduction of glycoside hydrolase to the pre-treated mixture at conditions sufficient to produce a sugar composition mixture for fermentation steps. The present invention provides methods for loading biomass mixtures in a batch-fed process, wherein the biomass slurries can be loaded into water or a concentrated sugar composition for hydrolysate production. The methods can be performed in a one-pot process, wherein the ionic liquids are present in the mixtures throughout each step. Aspects of the invention provide compositions of sugar composition mixtures and fermentation product mixtures.

A wood-derived carbohydrate composition is disclosed. The wood-derived carbohydrate composition comprises monomeric C6 sugars and monomeric C5 sugars in a total amount of at least 80 weight-% based on the total dry matter content of the carbohydrate composition. The ratio of the monomeric C5 sugars to the monomeric C6 sugars is at most 0.15. Disclosed is also a method for producing a wood-derived carbohydrate composition.

An object of the present invention is to provide a particulate composition containing crystalline α,α-trehalose dihydrate, having an advantageous emulsifying ability. The above object is solved by providing a particulate composition comprising crystalline α,α-trehalose dihydrate, which consists of particles containing α,α-trehalose and maltose and/or maltotriose, wherein said particulate composition contains α,α-trehalose in an amount of 70% by weight or higher but 90% by weight or lower, on a dry solid basis; and maltose and/or maltotriose in a total amount of 3% by weight or higher, on a dry solid basis; and has a degree of crystallinity for crystalline α,α-trehalose dihydrate of 25% or higher but less than 90%, when calculated based on its powder X-ray diffraction profile.

The invention relates to a process for the preparation of a sugar and/or fermentation product from lignocellulosic material.

A method for processing lignocellulose materials comprising the steps of hydrothermal treatment of the material with saturated or superheated steam in a hydrothermal pressure vessel, wherein the steam is provided by means of a steam boiler. The treatment is performed at a pressure of 5-30 bars, and at a temperature of 160-240° C. for a duration of 1-20 minutes. The method further comprises discharging hydrothermally treated lignocellulose material and steam from the pressure vessel by means of rapid pressure reduction, separating the steam and vapours released from the lignocellulose material, and burning the vapours together with additional fuel and combustion air in the furnace of said steam boiler. Furthermore, a corresponding system is provided.
