Embodiment 1
[0048] Take by weighing sweet potato vine powder 100Kg, glucose 3Kg, nutrient salt 0.5Kg, water 200Kg and lactic acid bacteria (the live bacteria concentration of lactic acid bacteria is 1.0 * 10 6 CFU / g) 10Kg was stirred at 2000r / min for 3min, and then the mixture was anaerobically fermented at 25°C for 24h to obtain a lactic acid bacteria fermentation broth. Mix the obtained lactic acid bacteria fermentation broth with citric acid (the mass ratio of sweet potato vine powder and citric acid is 20:1), obtain the citric acid mixed solution, adjust the pH value to 7, mix it with Aspergillus niger, and ferment it at 28°C for 72h to obtain Aspergillus niger fermentation broth. Mix the obtained Aspergillus niger fermentation liquid with cellulase, pectinase and protease in a mass ratio of 100:0.1:0.05:0.005, carry out enzymolysis at 35°C for 12 hours, filter, collect the filtrate and filter residue respectively, and obtain the filtrate For soluble dietary fiber.

Embodiment 2
[0051] Take sweet potato vine powder 100Kg, glucose 5Kg, nutrient salt 0.2Kg, water 400Kg and lactic acid bacteria (the live bacteria concentration of lactic acid bacteria is 1.0 * 10 9 CFU / g) 5Kg was stirred at 2000r / min for 3min, and the mixture was anaerobically fermented at 30°C for 18h to obtain a lactic acid bacteria fermentation broth. Mix the obtained lactic acid bacteria fermentation broth with citric acid (the mass ratio of sweet potato vine powder and citric acid is 100:1), obtain the citric acid mixed solution, adjust the pH value to 6, mix it with Aspergillus niger, and ferment it at 32°C for 36h to obtain Aspergillus niger fermentation broth. Mix the obtained Aspergillus niger fermentation liquid with cellulase, pectinase and protease in a mass ratio of 100:0.5:0.01:0.05, carry out enzymolysis at 50°C for 8 hours, filter, collect the filtrate and filter residue respectively, and obtain the filtrate For soluble dietary fiber.

Embodiment 3
[0054] Take sweet potato vine powder 100Kg, glucose 4Kg, nutrient salt 0.35Kg, water 300Kg and lactic acid bacteria (the live bacteria concentration of lactic acid bacteria is 1.0 * 10 8 CFU / g) 8Kg was stirred at a speed of 2000r / min for 3min, and the mixture was anaerobically fermented at 28°C for 20h to obtain a lactic acid bacteria fermentation broth. Mix the obtained lactic acid bacteria fermentation liquid with citric acid (the mass ratio of sweet potato vine powder and citric acid is 100:3), obtain the citric acid mixed liquid, adjust the pH value to 6.5, mix it with Aspergillus niger, and ferment it at 30°C for 55h to obtain Aspergillus niger fermentation broth. Mix the obtained Aspergillus niger fermentation broth with cellulase, pectinase and protease in a mass ratio of 100:0.3:0.03:0.03, carry out enzymolysis at 42°C for 10 hours, filter, collect the filtrate and filter residue respectively, and obtain the filtrate For soluble dietary fiber.
