Embodiment 1
[0019] Example 1: Dry the Jerusalem artichoke residue that has extracted the inulin to a water content of 8% at a temperature of 80° C., pulverize it with a pulverizer, pass through a 60-mesh sieve, and add 15 tons of the above-mentioned processed Jerusalem artichoke residue to 1 ton of water, then add 25 kg of sodium carbonate, adjust the pH value of the solution to 7.0, stir at 70°C for 30 minutes, centrifuge to separate the decolorizing liquid, then wash the centrifuged Jerusalem artichoke residue with water until it flows out When the solution is colorless; then add 15 tons of water to the washed Jerusalem artichoke residue, adjust the pH value of the solution to 2.1 with hydrochloric acid, stir for 60 minutes at a temperature of 80°C, and then filter through a plate frame to filter out the pectin-containing The liquid, the filter residue is used to make dietary fiber, and the filtrate is filtered through a 0.22um microfiltration membrane to filter out a clear pectin-contai...
Embodiment 2
[0021]Example 2: Dry the chicory dregs after extracting the inulin to a water content of 7% at a temperature of 85° C., pass through an 80-mesh sieve after pulverizing with a pulverizer, and add 13 tons of water to 1 ton of the above-mentioned processed chicory dregs , then add 20 kg of sodium carbonate, adjust the pH value of the solution to 6.8, stir at a temperature of 75°C for 35 minutes, centrifuge the decolorized liquid with a centrifuge, then wash the centrifuged chicory residue with water until the effluent is Stop when colorless; then add the washed chicory residue to 14 tons of water, adjust the pH value to 2.3 with hydrochloric acid, then stir for 75 minutes at a temperature of 78°C, and then filter through a plate frame to filter out the pectin-containing liquid , the filter residue is used to make dietary fiber, and the filtrate passes through a 0.45um microfiltration membrane to filter out a clear pectin-containing liquid; the above liquid is concentrated with an ...
