[0016] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.
[0017] A process for decolorizing and deproteinizing the jelly grass polysaccharide liquid. First, the selected dried jelly grass is boiled for 2 hours with 0.4% sodium carbonate aqueous solution of 20 times the volume, and then filtered until clarified; Adjust to 6.0, when the temperature is 70℃, slowly add 4% ZTC-ⅡB clarifier while stirring, the concentration of ZTC-ⅡB clarifier is 1%, stop stirring for 1 hour after adding, when the temperature drops to 50℃ Slowly add 2% ZTC-ⅡA clarifier while stirring, the concentration of ZTC-ⅡA clarifier is 1%, stop stirring after adding, raise the temperature to 80°C, and let stand for 15 minutes; then use a tube centrifuge to remove the precipitate Filter and remove the filtrate, adjust the pH of the filtrate to 5.5, keep the temperature at 45°C, control the flow rate at...
