ABSTRACT
Rye hybrids were proved to be a very good raw-material for ethanol production, as good as a regular variety. The most profound difference found in chemical composition of hybrids and a regular variety was higher level of pentosanes, reaching from 7.6 to 9.2% of dry matter. Applying hemicellulase enzyme in the mashing process as the additional enzyme is particularly reasonable for rye hybrids. Taking into account higher productivity of hybrid varieties, the ethanol yield from hectare of land might be up to 40% higher in comparison with a regular rye grain.
Key words: ethanol, rye hybrids, hemicellulase.
