The invention discloses a method for improving banana
fruit wine appearance quality stability through membrane
filtration, which has the technical scheme that bananas are peeled, color protecting liquid is added for enzymolysis,
fermentation liquid is regulated, the
alcohol fermentation is carried out, the
wine slag is separated, a
ceramic membrane is used for
filtration, and
wine is bottled and stored. The method has the advantages that the quality of the banana
fruit wine is improved, the appearance is clear and transparent, the
transmission rate of the
wine liquid reaches higher than 95 percent, simultaneously, the loss of the
ethanol content and the mineral
substance content in the wine liquid is reduced, the number of microbes in the
fruit wine is reduced, the biological stability isimproved, the membrane separation has the characteristics of high separation efficiency, lower
energy consumption, simple operation and the like, substances of
thallus cells, macromolecular
protein and the like can be effectively stopped, and the degerming rate reaches higher than 50 percent. Compared with the traditional high-temperature sterilization and chemical clarification method, the method has the advantages that the adverse influence on the
flavor and
nutrient components of the wine after the high-temperature sterilization can be avoided, in addition, the addition and reside problemsof external chemical substances can be avoided, and good application prospects are realized.
