The invention discloses a method for
processing blueberry
wine. The method comprises the steps: screening out and cleaning fresh and
disease-free blueberries; and mixing the blueberries with
bran, pulping,
processing with composite
enzyme, squeezing juice, filtering, conducting enzymatic method clarification, ultrafiltrating, conducting
yeast fermentation, clarifying,
ageing, packaging, and sterilizing to obtain products. The juice yield of the blueberries can be improved and the color of the blueberry juice can be stabilized by mixing the
bran and the blueberries and combining the enzymolysis technology of the complex
enzyme; by adopting
lactic acid after-
fermentation deacidification technology, the content of
malic acid in the blueberry juice can be reduced, and the categories of organic acids and the flavors of blueberry
wine can be improved; and by adopting the technology of ultrafiltrating and clarifying the blueberry
wine, the defects of bad effects due to adoption of a natural clarification method and single clarification agent can be overcome, the brewed blueberry wine is thick in fruity
flavor, stable in color, mellow in mouthfeeling, and good in quality, and the utilization ratio of raw materials are improved.
