A kind of decolorization method of Sapindus saponin

Abstract

A method for decolorizing sapindus saponin, comprising the following steps: (1) weighing dried sapindus saponin powder, adding 0.6 times the quality of deionized water, stirring at room temperature to completely dissolve it; (2) by Metal complex hydrides and acidic sulfites are mixed in a mass ratio of 4:3 to 4:36 to prepare a composite decolorizer; (3) after adjusting the pH of the sapindus saponin solution in step (1) to 4.5-6.5 , add the compound decolorizing agent prepared in step (2), the addition amount is weighed according to the mass ratio of Sapindus sapinsin powder and compound decolorizing agent 100:1~100:5, and reduce and decolorize at a temperature of 20°C-70°C for 30 ‑80min; (4) Spray-dry the Sapindus Sapindus total saponins solution after decolorization in step (3) to obtain decolorized saponin powder. The composite decolorizing agent of the present invention has a synergistic effect, less decolorizing agent dosage, good decolorizing effect, short decolorizing time, low production cost, less impact of waste liquid on the environment, less target product loss in the decolorizing process, high efficiency, time saving, The advantages of environmental 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 ...
