Abstract
A process for preserving biomass material comprising polysaccharide, the process comprising contacting the biomass material with a preserving composition comprising alcohol to form a preserved biomass material and storing the preserved biomass material for at least 24 hours. At least a substantial amount of the polysaccharide may be extracted from the preserved biomass material with yields comparable to or improved over extraction from fresh non-preserved biomass material.
