The invention discloses a preparation method of compound noni
fruit wine. The preparation method includes the following steps that 1, noni fruits are cleaned and placed for after-
ripening and are crushed and pulped;
pectinase is added for enzymolysis, and
filtration is performed to obtain noni
fruit juice; 2, the other fruits are cleaned, chopped and juiced, and then the supernate is obtained so as to obtain other
fruit juice; 3, the noni
fruit juice and other fruit juice are mixed by the volume ratio of (3-11) to 1,
cane sugar,
citric acid and
potassium bicarbonate are added to adjust the pH value and the the
sugar degree which are 6.0-7.5 and 16-22oBx respectively, and high-temperature sterilization and
enzyme deactivation are performed; 4, 40-120 mg / L SO2 solution is added into the product obtained in the step 3; 5,
fermentation is performed: active dry
yeast is activated, then the product obtained in step 4 serves as a
fermentation substrate, and the activated active dry
yeast is added to perform
fermentation; 6,
fermentation broth is filtered, a sterilized fermentation tank is filled with the product, and after fermentation is performed; 7, the compound noni
fruit wine is obtained through aging,
filtration, sterilization and filling. The invention further discloses the
fruit wine prepared by means of the method.
