Optimization of clarification technology of Shoumei Chenpi white tea wine
Using chitosan,bentonite,gelatin,polyvinylpyrrolidone(PVPP),tannin and diatomite as clarifying agents,Shoumei Chenpi white tea wine was clarified,and the clarification effect was investigated.Using transmittance and sensory score as evaluation indicators,the types of clarifiers and clarification conditions were optimized by using single factor experiments and orthogonal experiments.The results showed that bentonite and chitosan had the optimal clarification effect,and the optimal clarification process was bentonite-chitosan mass ratio 1∶1,addition 0.6 g/L,clarification tempera-ture 30 ℃,and time 21 h.Under the optimal conditions,the transmittance of the Shoumei Chenpi white tea wine was 93.8％,total acid content was 4.1 g/L,alcohol content was 6.2％vol,and sensory score was 94,indicating that the clarification process was feasible.
