The critical processing technology of compound wine using compound juice of plum pulp and sugar cane juice(1∶1,w/w) as materials was studied,including enzymolysis technology on plum pulp,fermentation parameters and clarification technology of plum wine.The results showed that the optimal conditions for plum pulp were enzymatic concentration 251.5 mg/L,temperature 45℃,reaction time 4h.The optimalconditions for fermentation were inoculation amount 5%,SO2 addition 100mg/L,initial pH3.2,temperature 28℃.Bentonite is the best clarification agent for plum wine among gelatin,bentonite and chitosan.The optimal conditions for clarification were concentration 0.08g/100 mL,temperature 25℃,reactiontime10h.
