Abstract

The invention provides a novel stevioside production method. The novel stevioside production method comprises the following steps in the technological process: (1) operatiing an adsorption area, namely allowing a clear stevioside flocculation filtrate from a clear stevioside flocculation filtrate raw material tank to enter a resin tower N1 through a clear stevioside flocculation filtrate feeding pipe, wherein stevioside components are adsorbed by resin, and allowing tail liquid produced by the adsorption of the clear stevioside flocculation filtrate to enter a tail liquid tank through an adsorption tail liquid discharging pile; and (2) operatiing an replacement stevioside flocculation filtration area, namely allowing a replacement fluid A from a replacement fluid A tank to enter a resin tower N2 though a replacement fluid A feeding pipe when the resin is saturated after the adsorption, and pushing the clear stevioside flocculation filtrate, of which the stevioside is not yet adsorbed,back to the clear stevioside flocculation filtrate raw material tank so as to wait for the next adsorption. The novel stevioside production method is simple and easy to operate, and combines specificity of stevioside adsorption processes; and thus, compared with an existing current fixed bed production process, the utilization rate of the resin can be improved by 50% or above, the utilization efficiency of the resin can be increased by 60% or above, and the production cost can be reduced by 30-50%.

Description

technical field [0001] The invention relates to the technical field of stevioside production, in particular to a new method for stevioside production, which belongs to the field of food additive processing. Background technique [0002] Stevioside (commonly known as stevioside, steviol glycoside) is a new type of natural sweetener extracted from the Compositae herb stevia (or stevia leaf), and South America has used stevia as a medicinal herb and sugar substitute. Hundreds of years of history. Information from the international sweetener industry shows that steviol glycosides have been widely used in the production of food, beverages, and seasonings in Asia, North America, South America, and EU countries. China is the world's largest producer of steviol glycosides. The current domestic production of stevioside is basically carried out by extraction, flocculation, filtration, resin adsorption, resin refining, evaporation, spray drying and other processes. In China, resin a...
