The invention relates to a production technology of
alcohol-free wolfberry
fruit wine. The technology comprises the following steps: choosing dry wolfberry fruits as a
raw material, cleaning, rehydrating, crushing, extracting to obtain an extract juice, carrying out
enzyme treatment, adjusting components, and carrying out low temperature
fermentation, or choosing fresh wolfberry fruits as a
raw material, cleaning, crushing, dipping, carrying out
enzymatic hydrolysis, adjusting components, and carrying out peel-containing low temperature
fermentation; and separating when the
alcohol degree reaches 3-7% and the
sugar content is 60-80g / l in order to remove
wine lees or peel residues, filtering the obtained wolfberry
fruit wine to remove
yeast in order to stop
fermentation,
ageing, carrying out vacuum rotary
evaporation to remove
alcohol in order to make the alcohol degree smaller than 0.5%, blending the alcohol-removed
fruit wine, and filtering to obtain the alcohol-free wolfberry fruit
wine. The technology reserves the original
nutrition of the
fruit juice, gives a certain fermentation
flavor by using a biological technique, controls the alcohol-free wolfberry fruit
wine to be a
fruit juice beverage with a low
ethanol content, and provides rich various nutritional components in the wolfberry fruit for people.
