Embodiment

[0034] A kind of production technology of jujube dry red wine, its concrete production and processing steps are as follows:

[0035] (1) Raw material selection: select high-quality ripe red dates from the pile of red dates;

[0036] (2) Cleaning raw materials: Rinse the selected red dates in running water for at least 10 minutes, then drain and set aside;

[0037] (3) Steaming: put red dates in a steamer, adjust the temperature in the steamer to 90°C, and steam for one hour;

[0038] (4) Cooling: Take the jujube out of the steamer and cool it down for 30 minutes;

[0039] (5) Fermentation: Put the cooled jujube into a fermenter, add water that accounts for 4 times the weight of the jujube in the fermenter, adjust the sugar content of the mixture in the fermenter to 20%, and adjust the pH to between 3.5 and 4.0 ; Sterilize; add Angel yeast accounting for 0.3% of the capacity of the fermenter tank; adjust the temperature in the fermenter to 20° C. to 25° C., and ferment at a c...

Abstract

The invention provides a production technology of dry red wine with red dates. The production technology comprises the following steps: selecting raw materials, cleaning, steaming and maintaining, and cooling; adding the raw materials to a fermentation tank, and fermenting; separating residues from pulp; ageing; firstly, filtering the aged pulp with kieselguhr, and carrying out super membrane filtration; and bartending, filling and sterilizing. The production technology of the dry red wine with red dates has the beneficial effects that the steps of extracting juice, degumming and clarifying are omitted; the technological process is relatively simple and convenient; as the degumming link is omitted in the overall technological process, the problem that the wine is difficult to filter is solved, and the filtering time is greatly shortened; a traditional chitosan clarifying process is replaced with super membrane filtration, so that the wine can be free of a sediment and good in color after being stored for a long period of time; the production technology of the dry red wine with red dates provided by the invention is an original fruit fermentation process; and the produced fermented wine is relatively strong in red date aroma and relatively good in taste.

Description

technical field [0001] The invention relates to the technical field of fruit wine production and processing, in particular to a production process of jujube dry red wine. Background technique [0002] Dry red wine refers to red wine in which the sugar in the winemaking raw materials is completely converted into alcohol after the wine is brewed, and the residual sugar content is less than or equal to 4.0g / L. Dry red wine is made from grapes, which are crushed and destemmed, adjusted, fermented, and aged. It contains more antioxidants, which can eliminate or resist oxygen free radicals. effect. In addition, dry red wine also has certain deficiencies, such as: the acidity and astringency of the swill flavor of dry red wine are difficult for people to adapt to. [0003] Based on the above shortcomings of traditional dry red wine, people have further improved the production process of dry red wine, and used red dates as raw materials. In addition, sugars such as fructose in ju...
