Increasing glycerine content in mash.Peer-reviewed article

V. GRÉGR, Z. KUTTELVAŠER

Since normal alcoholic fermentation is always companied by emergence of glycerine, the authors have elaborated and verified new technology for manufacturing glycerine, based on fermenting molasses in alkaline medium with addition of alkali earth carbonates or Na₂SO₃. The suggested method can be easily introduced on any molasses distillery without complicated adjustments of existing equipment. The total yield of ethyl alcohol and glycerine, at experiments carried out on a semi-production scale, was as high as 51,63 % calculated from the weight of sugar introduced into the process, the proportion of glycerine being 11,74 % [by weight] and of ethyl alcohol 39,89 %. The spirit manufactured by means of new technology is of the same quality as that fermented in conventional way, but the time required for fermentation is by 3 - 12 hours longer.
