At the University of Maine, a hemicellulose pre-extraction technology is now being investigated to improve pulp yields, reduce organic and inorganic load for liquor recovery, and create a feed stream for the generation of new biomaterials. In this study, we investigate 1. the extent of hemicellulose recovery by pre-extraction using green liquor pretreatment and 2. characterize the hydrolysis of the extract with respect to variable concentration via evaporation and comparing acid and enzymatic hydrolysis.
