METHOD FOR TREATMENT OF MUST AND WINE-MATERIAL WITH BENTONITE Russian patent published in 2004 - IPC

FIELD: wine-making industry. SUBSTANCE: method for treatment of must and wine-materials involves feeding to them bentonite. Bentonite is ground preliminary, subjected for wetting and swelling in soda solution. Swollen bentonite is poured with water acidified with hydrochloric acid to pH 3.4-3.6 in the ratio = (1:4)-(1:5) to bentonite mass, stirred and settled for 4-5 h. Settled part is separated, washed out with water to pH 6.8-7.0 and dried to dry powder-like state. Proposed method provides significant reducing the main product loss due to diminished volume of gluing and must precipitates, to prevent enrichment of must and wine-material with calcium cations, to retain stability of ready product, to reduce labor cost in feeding bentonite suspension and to get free industrial area and capacities. Invention can be used in clearance and stabilization of must, juices and wine-material. EFFECT: improved treatment method. 2 cl, 1 tbl, 8 ex
