Embodiment 1
[0041] Select 250kg fresh ivy fruit, 50kg black tiger fresh fruit and 100kg blueberry fresh fruit raw materials without rot, wash them, remove seeds, mash them and beat them into pulp to obtain creeper fruit pulp. Take 400kg of creeper fruit pulp, add 1200L of 75% ethanol solution, adjust the pH value to 4.5 with 0.1mol / L hydrochloric acid, stir and extract at room temperature for 50h, filter once with two layers of gauze, and filter once with a ceramic membrane to obtain the filtrate and filter residue, The resulting filtrate was concentrated to 50L under reduced pressure below 50°C, adsorbed on LSA-7 macroporous resin, and eluted with 15BV of 70% ethanol aqueous solution in a gradient, and the eluate was collected, and the eluate was decompressed below 50°C Concentrate to dryness, obtain 16kg creeper pigment. Add 350 L of water to 150 kg of filter residue, stir for 50 minutes, and filter to obtain the filtrate and creeper pomace for later use. The filtrate is concentrated to...
Embodiment 2
[0043] Take 150 kg of the ivy pomace obtained in Example 1, add 150 kg of water, then add 350 g of pectinase, stir evenly, adjust the pH to 3.5, enzymolyze at room temperature for 4 hours, put it into a fermenter, and obtain about 300 L of enzymolyzed solution. Add 18kg of sucrose to the enzymolysis liquid, steam sterilize at 121°C for 25 minutes, add 15kg of baker’s yeast directly after cooling, aerobically ferment for 36 hours, finish fermentation, and then ultrasonically treat for 35 minutes to obtain a treatment solution, immediately add 30kg of lactic acid bacteria CGMCC No to the treatment solution .1.1854, after stirring evenly, sealed and carried out anaerobic fermentation at 37°C for 3 days to obtain a fermented liquid. Use 3 layers of gauze to filter the fermentation broth, and then filter it with a microporous filter with a pore size of 0.6-1.0 μm, which is the black tiger feed solution. 120g black tiger feed liquid, 10g xylitol, 40g creeper extract (obtained in Exa...
Embodiment 3
[0045] Take 250 kg of the ivy pomace obtained in Example 1, add 250 kg of water, then add 500 g of pectinase, stir evenly, adjust the pH to 3.5, enzymolyze at room temperature for 4 hours, put it into a fermenter to obtain about 500 L of enzymolyzed solution. Add 35kg of sucrose to the enzymolysis solution, sterilize by steam at 121°C for 20 minutes, add 18kg of baker’s yeast directly after cooling, aerobically ferment for 45 hours, finish fermentation, and then ultrasonically treat for 40 minutes to obtain a treatment solution, immediately add 40kg of lactic acid bacteria CGMCC No to the treatment solution .1.1854, after stirring evenly, sealed and carried out anaerobic fermentation at 37°C for 2.5 days to obtain a fermented liquid. Use 3 layers of gauze to filter the fermentation broth, and then filter it with a microporous filter with a pore size of 0.6-1.0 μm, which is the creeper feed solution. 150g of creeper feed liquid, 12g of xylitol, 35g of creeper extract (obtained ...
