Claim:
1. A method of producing a hydrolysate containing sugar from a lignocellulosic biomass, comprising the steps of: a) pretreating the lignocellulosic biomass in a pretreatment process to form a slurry comprising cellulosic particles; b) saccharification of the slurry obtained in step a) in the presence of hydrolytic enzymes in an enzymatic hydrolysis process to obtain a hydrolysate containing sugar; c) analyzing cellulosic particles present in the slurry obtained in step a) and/or cellulosic particles present in the enzymatic hydrolysis process during step b) using an image analysis method to obtain a data set; and d) controlling at least one process parameter of the pretreatment process in step a) and/or enzymatic hydrolysis process in step b) in response to the data set obtained in step c); wherein the image analysis in step c) is a visible spectrum image analysis.
