Embodiment 1

[0022] (1) Strain collection, domestication and expanded cultivation: crush the freshly collected alpine grape skins and squeeze them, collect the squeezed liquid, add agar to the liquid, heat, dissolve and sterilize it to make 18 test tube slopes For the culture medium, select 18 freshly collected alpine grapes with good growth, gently scrape off the "white ash" on the skin of each grape, and inoculate them on the slant medium respectively, screen the test tube slant medium with good growth, and acclimatize For the 5th generation, the domesticated "white ash" was expanded and cultivated to obtain a mixed strain for fermenting and making alpine wine.

[0023] (2) Ingredients and fermentation: Wash the freshly collected alpine grapes, drain the water, remove the stems and break them, mix them well, add the mixed strains obtained in (1), and ferment them at a temperature of 25-35°C. Add 4.5% sucrose and mix evenly after 12 hours, continue to add 4.5% sucrose and mix evenly after...

Embodiment 2

[0027](1) Strain collection, domestication and expanded cultivation: crush the freshly collected alpine grape skins and squeeze them, collect the squeezed liquid, add agar to the liquid, heat, dissolve and sterilize to make 4 test tube slopes For the culture medium, select 4 freshly collected alpine grapes with good growth, gently scrape off the "white ash" on the skin of each grape, and inoculate them on the slant medium respectively, screen the test tube slant medium with good growth, and acclimatize In the 4th generation, the domesticated "white ash" was expanded and cultivated to obtain a mixed strain for fermenting and making alpine wine.

[0028] (2) Ingredients and fermentation: Wash the freshly collected alpine grapes, drain the water, remove the stems and break them, mix them well, add the mixed strains obtained in (1), and ferment them at a temperature of 25-35°C. Add 3.1% sucrose and mix evenly after 12 hours, continue to add 3.1% sucrose and mix evenly after 48 hou...

Abstract

The invention discloses a comprehensive utilization method of mountain grapes. Companion fungi, namely frost, on peels of the mountain grapes are subjected to domestication and cultivation enlarging in a grape peel squeezing solution, and a mixed strain for fermenting and manufacturing mountain wine is obtained; secondly, the mountain grapes are cleaned and drained, stems are removed, the mountain grapes without stems are smashed, the mixed strain is inoculated, cane sugar is added at 25-35 DEG C for fermentation, filtering is conducted when the sugar content in a fermentation solution is smaller than or equal to 7 g / L 5-7 days after fermentation, filter residues are dried, the peels serve as animal feed, grape seed oil and procyanidine are separated from seeds through the supercritical continuous extraction method, the filtrate continues to be fermented till the sugar content is smaller than or equal to 4 g / L, upper layer liquor is siphoned out, bottom layer yeast paste is abandoned, the product continues to be fermented for 15-30 days at 15-30 DEG C, and dry red type mountain wine is obtained. Multiple technologies are effectively integrated, the optimal comprehensive utilization effect of the mountain grapes is achieved, market competitiveness is high, and application prospects are broad.

Description

technical field [0001] The invention relates to a comprehensive utilization method of alpine grapes, which belongs to the field of agricultural product processing. Background technique [0002] Alpine Vitis vinifera is a thorny grape species in the East Asian population. It is a powerful vine native to the Xuefeng mountainous area in the south. It is domesticated and selected in the high temperature, humidity and low light ecological environment. The young leaves of alpine grapes are purple-red, and the mature leaves are heart-shaped, large and thick, smooth, dull, with blunt serrated edges. The sugar content of mature alpine grapes is as high as 20%, and the honey aroma is strong. Not only is the fresh food quality good, but the wine quality is also top-notch. It will end the situation that wineries in southern my country cannot make high-end wine due to poor raw material quality. And it will be used as the first choice raw material for brewing high-end wine to improve the ...
