| titleOfInvention | Method for decoloring soapberry saponin |
| abstract | A method for decolorizing sapindoside comprises the following steps: (1) weighing dried soapberry saponin powder, adding deionized water with the mass of 0.6 time of that of the soapberry saponin powder, and stirring at room temperature to completely dissolve the soapberry saponin powder; (2) metal complex hydride and acidic sulfite are mixed according to the mass ratio of 4: 3-4: 36 to prepare a composite decolorant; (3) adjusting the pH value of the soapnut saponin solution obtained in the step (1) to 4.5-6.5, adding the compound decolorizing agent prepared in the step (2), wherein the adding amount is determined according to the ratio of soapnut saponin powder to the compound decolorizing agent 100: 1-100: 5, and reducing and decoloring for 30-80min at the temperature of 20-70 ℃; (4) and (4) carrying out spray drying on the decolorized soapberry total saponin solution in the step (3) to obtain decolorized saponin powder. The composite decoloring agent has a synergistic effect, and has the advantages of small using amount of the decoloring agent, good decoloring effect, short decoloring time, low production cost, small influence of waste liquid on the environment, less loss of target products in the decoloring process, high efficiency, time saving and environmental protection. |
