The invention relates to the technical field of preparing a nutritive
wine from red dates as raw materials through
fermentation, and in particular relates to a red date nutritive
wine and a preparation method thereof. The red date nutritive
wine is prepared according to the following steps of: removing impurities from red dates which are used as raw materials, washing, soaking, heating and cooking the red dates, removing date pits and date skins, beating a red date pulp, adding water, adding pectase and
cellulase, adjusting the pH value, preserving the heat, performing enzymolysis, and then squeezing to obtain a red date juice; and inoculating
Kluyveromyces marxianus thalli suspension according to the red date juice, preserving the heat, performing anaerobic
fermentation to obtain a fermented wine solution, then performing high-speed
centrifugation to remove residues, performing membrane separation and refined
filtration, and performing low-temperature vacuum concentration and
reflux concentration on the wine solution to obtain a semi-finished product of the red date nutritive wine. The preparation method is reasonable and high in production efficiency; a clear juice is adopted for
fermentation, so that the generation of harmful substances such as
methanol and the like is reduced, and the product safety is high; and the raw materials are fully used, so that the defects that like products are high in
sugar content and low in
active ingredient content in the prior art are overcome.
