Brewing process of sweet potato wine

Abstract

The invention relates to a brewing process of sweet potato wine, and the brewing process comprises the following steps: (1) selection and pretreatment of raw materials; (2) pH adjustment; (3) pasteurization; (4) inoculation; (5) main fermentation; (6) post fermentation; (7) alcohol adjustment; (8) aging; and (9) bottling. The brewing process has the advantages that the processing method is simple,the production cost is low, the energy is saved, original healthy substances of sweet potatoes are effectively retained, the mouthfeel and the flavor of the sweet potatoes are outstanding, and the quality of the finished wine is stable.

Description

technical field [0001] The invention relates to the field of agricultural product processing, in particular to a brewing process of sweet potato wine. Background technique [0002] Most of the existing sweet potato wine production in my country is small-scale production or farm production. The production process is not energy-saving, and the sweet potato processing process takes a long time to damage the material components of the sweet potato itself; part of the production process is to dry the sweet potato first, and then dry it The shredded sweet potato is steamed in a steamer, and this method has the following disadvantages: firstly, the process of processing the sweet potato into a shredded sweet potato needs to consume a large amount of dry processing energy, and the shredded sweet potato needs to consume a large amount of energy for a long time by steaming the shredded sweet potato; The production process used by some manufacturers to save energy for drying is: first se...

[0002] Most of the existing sweet potato wine production in my country is small-scale production or farm production. The production process is not energy-saving, and the sweet potato processing process takes a long time to damage the material components of the sweet potato itself; part of the production process is to dry the sweet potato first, and then dry it The shredded sweet potato is steamed in a steamer, and this method has the following disadvantages: firstly, the process of processing the sweet potato into a shredded sweet potato needs to consume a large amount of dry processing energy, and the shredded sweet potato needs to consume a large amount of energy for a long time by steaming the shredded sweet potato; The production process used by some manufacturers to save energy for drying is: first select sweet potatoes of appropriate size and place them in the sun for 4 to 5 days; put the dried sweet potatoes into a steamer and cook until they are fully cooked, then take out the steamed sweet potatoes and spread them Dry, peel, and cool; then put the cooled sweet potatoes into the pot again, add water and simmer for 2-3 hours

There are following disadvantages in adopting this technique: the whole sweet potato needs to be steamed thoroughly and simmered for 2-3 hours for secondary processing, and the overall time is up to several hours, which consumes a lot of energy; manual peeling is adopted, and the labor intensity of workers is large and expensive. For a long time, the material composition of the sweet potato itself is greatly damaged in the repeated cooking process; the raw material formula of the sweet potato wine produced by the prior art is single, and there is only one raw material sweet potato, which makes the brewed wine have a single taste
