Production of vinegar from yeast sediments obtained from wine-making wastes

Production of vinegar from yeast sediments obtained from wine-making wastes. Zautashvili, M. I.; Maglakelidze, G. G. ("Samtrest" Georgian Industrial Enterprises of the Wine-Making Industry, USSR). U.S.S.R. SU 589251 25 Jan 1978 From: Otkrytiya, Izobret., Prom. Obraztsy, Tovarnye Znaki 1978, 55(3), 73. (Russian). (Union of Soviet Socialist Republics). CODEN: URXXAF. CLASS: IC: C12J001-00. APPLICATION: SU 76-2405980 20 Sep 1976. DOCUMENT TYPE: Patent CA Section: 17 (Foods) Section cross-reference(s): 16 Calcium tartrate [3164-34-9] was obtained together with vinegar and vinegar quality was improved by mixing the yeast sediments with H2O at a ratio of 1:1-1:1.5, cooling to 5-10°, filtering, and dividing the filtrate into 2 streams. One of the streams, 30-5%, contg. 18-24% dry matter and 9-12 vol.% alc. is directed towards addnl. filtration, pasteurization, and fermn., the other stream, 65-70%, is distd. with subsequent sepn. of Ca tartrate.

Production of calcium tartrate and feed from wine industry wastes-yeast residues

Production of calcium tartrate and feed from wine industry wastes-yeast residues. Kozub, G. I.; Murza, T. P.; Paraska, P. I.; Topor, V. P. ("Yaloveny" Scientific-Industrial Agricultural Enterprises, USSR). U.S.S.R. SU 616278 25 Jul 1978 From: Otkrytiya, Izobret., Prom. Obraztsy, Tovarnye Znaki 1978, 55(27), 94. (Russian). (Union of Soviet Socialist Republics). CODEN: URXXAF. CLASS: IC: C12G001-02. APPLICATION: SU 77-2452218 11 Feb 1977. DOCUMENT TYPE: Patent CA Section: 16 (Fermentations) Section cross-reference(s): 17 Title process consisted of mixing the wastes with H2O, distg. the mixt. into crude alc. and mash, filtering the mash, which gave a filtrate and a solid phase, multistage washing of the solid phase of the mash with hot H2O, treating the filtrate with calcined soda, neutralizing the mixt., removing Ca tartrate [3164-34-9] and drying it. The solid phase is used as feed. Prior to filtering, ground corn stalk particles of 0.8-1.0 mm and bentonite (15-20% and 5-10% of the mash by wt., resp.) were added successively to the mash while mixing. The solid phase was washed with a filtrate in the 1st stage and the filtrate treated with calcined soda to pH 6.0-6.5°. The solid phase was dried to 5-10% moisture content.
