Abstract

The invention provides a stevioside saponin decolorizing resin and a preparation method thereof, including suspension polymerization, hydrolysis to prepare intermediate spheres, epoxy chlorohydrin to prepare epoxy spheres, amination, and its application in stevioside solution decolorization ;Introduce hydroxyl groups on the strong base group as the main decolorizing functional group to achieve better contact between the stevioside liquid and the resin surface, to ensure that the decolorizing group can react with the pigment more easily and remove it, so that the resin can decolorize completely , High yield, low sugar loss and good resin strength.

Description

technical field [0001] The invention relates to the application field of resin in plant extraction, in particular to a steviol saponin decolorizing resin used in the refining process of stevia, and a preparation method and application thereof. Background technique [0002] The decolorization step involved in the refining process of stevia, the earliest process is to use activated carbon decolorization, and then gradually evolved into the resin method. At present, the application of resin in stevia decolorization has problems such as large sugar consumption, poor anti-pollution performance of resin, incomplete decolorization and poor resin strength. [0003] In the prior art, the application situation of the stevia decolorizing resin described in the patent CN102020745A feedback that the resin has good decolorization performance but still has the problems of general resin anti-pollution performance, short service life, and the problem of high cost of the resin and large pollu...
