Blueberry jam red wine and preparation method thereof

Abstract

The invention relates to the technical field of blueberry jam red wine, and particularly relates to a blueberry jam red wine and a preparation method thereof. The preparation method comprises the following steps: dividing blueberries into two aliquots and sugar into four aliquots, pulping one aliquot of blueberries, mixing together with one aliquot of sugar and water, controlling the temperature and the mixing speed, decocting into a concentrated paste, to obtain jam; then pulping the other aliquot of blueberries, mixing together with 1.5 aliquots of sugar, storing and fermenting for 1 day, stirring so as to be aerobically fermented when in storage and fermentation, then adding 1.5 aliquots of sugar, stirring and evenly mixing at high speed, storing and fermenting for 30 days, to obtain fermented liquor; then mixing the fermented liquor with the jam, further performing fermentation again, so that nutrients in the blueberries are fully leached, the mouthfeeling of the blueberry jam wine can also be improved, and the nutritional structure of the blueberries is more reasonable.

Description

technical field [0001] The invention relates to the technical field of blueberry jam red wine, in particular to a blueberry jam red wine and a preparation method thereof. Background technique [0002] Blueberry (Blueberry), also known as lingonberry and blueberry, is a deciduous evergreen shrub of the Rhododendronaceae Vaccinium. Blueberry fruit has extremely strong medicinal and nutritional health functions. According to the comprehensive analysis of 14 varieties of blueberry fruit imported from the United States by relevant departments, the content of anthocyanins per 100g of fresh fruit is as high as 163mg, protein 400-700mg, vitamin A up to 81-100 international units, vitamin E 2.7-9.5mg , SOD39 international unit, also rich in K, Fe, Zn, Ca and other mineral elements. According to relevant studies, it has strong antioxidant properties, can promote resynthesis of retinoid, improve circulation, anti-ulcer, anti-inflammation, improve immunity, enhance heart function, ant...

Problems solved by technology

For example, "A Production Method of Blueberry Red Wine" with the patent No. CN201110407686.2 discloses a technical scheme for preparing blueberry red wine by mixing and fermenting juice and slag after directly beating blueberries, thereby enriching the nutritional structure of blueberries and improving The pure aroma of blueberries in blueberry red wine improves the mouthfeel of blueberry red wine, and then advances the technical scheme of producing wine with blueberries as a raw material; at the same time, there is also "a blueberry mulberry dry red wine and its preparation method" as the patent No. CN201110165343.X Disclosed is a technical scheme for preparing red wine by mixing blueberries and mulberries, which makes the red wine richer in nutrition and lower in alcohol content, is suitable for middle-aged and elderly people to drink alcoholic beverages, and provides a combination type and additive blueberry red wine. However, in spite of this, in the prior art, there are many studies on blueberry red wine, but its effects are not ideal. The purpose of some technical documents is to prepare a kind of red wine with pure blueberry aroma, and what has is to prepare a kind of red wine with pure blueberry aroma. A kind of blueberry red wine with rich nutritional structure, and some are to add other substances to blueberries to prepare blueberry red wine with nutritional structure of blueberry and other substances; these technologies are generally aimed at improving the taste and quality of blueberry red wine

But the mouthfeel and the quality of the blueberry red wine obtained by these technical schemes are relatively unsatisfactory. At the same time, the blueberry is made into jam, and then the jam is combined with the primary product prepared by fermenting the blueberry, and it is subjected to secondary fermentation to improve its nutritional value. The technical literature of the blueberry red wine has not yet been reported
