Abstract

The invention relates to the field of resin synthesis, in particular to a preparation method of adsorbent resin separated and purified by stevioside and an application technology. The adsorbent resin can selectively adsorb stevioside specific components. The preparation method of the adsorbent resin separated and purified by stevioside comprises the following steps: mixing raw materials; adding an initiator and a pore-foaming agent; adding the mixture into a dispersion medium in a stirring state to perform a suspension polymerization reaction; and performing a curing reaction to obtain macroporous adsorption resin, namely, the adsorbent resin separated and purified by stevioside. According to the application technology of the adsorbent resin separated and purified by stevioside, the macroporous adsorption resin prepared with the method is subjected to chromatographic column adsorption, ethanol elution, concentration and drying. Compared with ordinary stevioside, stevioside prepared from the macroporous adsorption resin is higher in sweetness, is purer in mouthfeel, and is free from undesired aftertaste.

Description

technical field [0001] The invention relates to the field of resin synthesis, in particular to a preparation method and application technology of an adsorption resin for separation and purification of steviol glycosides. Background technique [0002] Steviol glycoside is a new type of natural sweetener extracted from the leaves of Stevia rebaudiana with high sweetness, low calorie, good taste, safety and non-toxicity. It can be widely used in food, beverage, medicine, daily Chemical industry and other industries. Steviol glycoside is a multi-component glycoside mixture. The sweetness and taste depend on its glycoside components and content. These different components have different tastes and can be used for different consumer groups. Among the nine known components of steviol glycosides, stevioside (abbreviated as Stv), rebaudioside A (abbreviated as RA), and rebaudioside C (abbreviated as RC) account for the vast majority, while rebaudioside D (abbreviated as RC) (referr...
