Embodiment 1

[0025] Weigh 6g of dried Sapindus saponin powder, add 100mL of pure water, stir at room temperature to dissolve completely; use hydrochloric acid to adjust the pH of the dissolved Sapindus saponin solution to 4.5, add potassium borohydride and sulfurous acid 60 mg of composite decolorizing agent prepared with sodium hydrogen at a mass ratio of 4:3, and reduced and decolorized at 20°C for 80 minutes; then spray-dried the above-mentioned decolorized Sapindus chinensis solution to obtain decolorized Sapindus sapindus saponin powder.

Embodiment 2

[0027] Weigh 12g of dried Sapindus saponin powder, add 200mL of pure water, stir at room temperature to make it completely dissolved; use sulfuric acid to adjust the pH of the dissolved Sapindus saponin solution to 5.0, add sodium borohydride and sulfurous acid Prepare 90 mg of compound decolorizing agent with sodium hydrogen at a mass ratio of 3:2, and reduce and decolorize it at 30°C for 70 minutes; then spray-dry the above-mentioned decolorized Sapinberry solution to obtain decolorized Sapinberry saponin powder.

Embodiment 3

[0029] Weigh 18g of dried Sapindus saponin powder, add 300mL of pure water, stir at room temperature to make it completely dissolved; use hydrochloric acid to adjust the pH of the dissolved Sapindus saponin solution to 5.5, add potassium borohydride and sulfurous acid 120 mg of composite decolorizing agent prepared with sodium hydrogen at a mass ratio of 1:5, and reduced and decolorized at 40°C for 60 minutes; then spray-dried the above-mentioned decolorized Sapinberry solution to obtain decolorized Sapinberry saponin powder.

Abstract

The invention discloses a soapnut saponin decoloring method which comprises the following steps: (1) weighing dried soapnut saponin powder, adding 0.6 times by mass of deionized water, and stirring ata room temperature to completely dissolve the soapnut saponin powder; (2) mixing composite metal hydride with acid sulfite in a mass ratio of (4:3)-(4:36) so as to obtain a composite decoloring agent; (3) adjusting the pH value of the soapnut saponin solution obtained in the step (1) to 4.5-4.6, adding the composite decoloring agent obtained in the step (2) according to a mass ratio of (100:1)-(100-5), and performing reduction decoloring for 30-80 minutes at 20-70 DEG C; (4) performing spray drying on the total soapnut saponin solution decolored in the step (3), thereby obtaining decolored saponin powder. The composite decoloring agent used in the method has a synergetic function, and the method is small in amount of the decoloring agent, good in decoloring effect, short in decoloring time, low in production cost, relatively small in environment influence caused by waste liquids and small in target product loss in the decoloring process, and has the advantages of high efficiency, timeshortening and environment protection.

Description

technical field [0001] The invention belongs to the technical field of biochemical research, and in particular provides a method for decolorizing the total sapindoside extract of sapindus chinensis. Background technique [0002] Sapindus mukorossi Gaertn. is a deciduous tree of the genus Sapindus L. in the family Sapindaceae, commonly known as Sapindus mukorossi Gaertn., soap tree, etc. It is mainly distributed in the warmer regions of America, Asia and Oceania. It is mainly produced in the Huaihe River Basin and south of my country. The fruits and roots of Sapindus chinensis are rich in sapindus saponins, oil compounds and a small amount of flavonoids, alkaloids, steroids and other secondary metabolites, as well as rich trace elements and proteins. Soapberry saponins are mainly triterpene saponins and sesquiterpene glycosides. Currently, more than 50 species of triterpene saponins and more than 10 species of sesquiterpenes have been identified. Sapindus saponins not only ...
