Fructus rosae roxburghii, blueberry and black tea wine and preparation method thereof

Abstract

The invention relates to the technical field of wine brewing, and in particular relates to fructus rosae roxburghii, blueberry and black tea wine and a preparation method of the fructus rosae roxburghii, blueberry and black tea wine. According to the fructus rosae roxburghii, blueberry and black tea wine and the preparation method, blueberries, fructus rosae roxburghii, black tea, prunus salicina fruits (with pulp and stones separated after ripening), pears, rice wine and active saccharomyces bayanus are reasonably mixed, so that the nutritional ingredients in the raw materials are sufficiently utilized, further, the quality of the fructus rosae roxburghii, blueberry and black tea wine is improved, and the nutritive value of the fructus rosae roxburghii, blueberry and black tea wine is enriched; meanwhile, in the preparation technology, due to the limitation of the processing steps including juicing, dreg primary steaming, braising, re-steaming and mixed fermentation, the active ingredients of blueberries, fructus rosae roxburghii, black tea, prunus salicina fruits and pears are sufficiently mixed, so that the mouthfeel and flavor of the wine are enriched, in addition, under the promoting effect of the added rice wine, the efficacies of the active ingredients in the raw materials are obviously exerted, and moreover, the fermentation treatment is carried out in the sealed environment, so that the oxidation loss of the nutritional ingredients is avoided, and the oxidation browning is avoided.

Description

technical field [0001] The invention relates to the technical field of wine production, in particular to a prickly pear blueberry black tea wine and a preparation method thereof. Background technique [0002] Blueberry is the fruit of deciduous evergreen shrubs belonging to the Rhododendronaceae Vaccinium genus. The pulp is rich in protein, dietary fiber, fat, vitamins and other nutrients, as well as trace minerals such as calcium, iron, phosphorus, potassium and zinc. It also contains precious Anthocyanins: The content of anthocyanins per 100g of fresh fruit is as high as 250mg, which has excellent antioxidant effect and ranks first among more than 40 kinds of vegetables and fruits with antioxidant effect. Blueberries are one of the top five healthy fruits recommended by the World Food and Agriculture Organization. [0003] Rosa roxburghii belongs to Rosaceae, a perennial deciduous climbing shrub with a height of 4-6m and vigorous growth. It has high medicinal value and h...

Problems solved by technology

[0004] For this reason, in the prior art, some researchers use prickly pear and blueberry as raw materials to prepare prickly pear blueberry brandy, which makes the obtained brandy rich in nutritional value, unique in flavor, comfortable in taste, and prevents the defects of poor quality caused by oxidative browning; but , the high content of tannin and total acid in Rosa roxburghii juice makes the methanol content of the prepared product higher, which hinders the application of Rosa roxburghii as a raw material in wine products; at the same time, the anthocyanins in blueberries are high in nutritional value. ingredients, but in the process of improper processing technology, it is extremely vulnerable to loss, resulting in poor product quality; at the same time, the traditional brandy product prepared by mixing prickly pears and blueberries has a single nutritional component and poor fruit flavor , so that the taste of the obtained wine products is less suitable for the crowd, which hinders its market prospect
