AI Technical Summary

Technical Problem

In the existing technology, the production of glucosylsteviosides results in a high content of unreacted glycosides, which leads to products that do not meet standards. Furthermore, existing methods are not effective in reducing the content of unreacted glycosides, which also affects the sweetness and taste of the product.

Method used

A multi-step preparation apparatus is used, including a conversion tank, a hydrolysis tank, a reaction tank, and a macroporous adsorption resin column. By using a combination of enzymes such as cyclodextrin glucoside transferase, α-amylase, and sucrase synthase, combined with UGT glycosyltransferase and ethanol desorption, the conversion and purification of unreacted glycosides are achieved, thereby reducing the content of unreacted glycosides.

Benefits of technology

It improves the product quality and taste of glucosylstevioside, reduces production costs, reduces waste of organic solvents, conforms to the concept of green chemistry, and extends the service life of equipment.

Abstract

The utility model discloses a preparation device of glucose stevioside, and relates to the technical field of glucose stevioside production, an inlet of a conversion tank is respectively communicated with a raw material tank, an auxiliary material tank and a cyclodextrin glucoside transferase tank, an outlet of the conversion tank is communicated with a hydrolysis tank, an outlet of the hydrolysis tank is communicated with a reaction tank, and the reaction tank is communicated with a reaction tank. The inlet of the reaction tank is respectively communicated with a sucrose tank, a sucrose synthase tank, a uridine diphosphate tank, a first UGT glycosyltransferase tank, a second UGT glycosyltransferase tank and an alkali liquor tank; an outlet of the reaction tank is communicated with a first macroporous adsorption resin column, an inlet of the first macroporous adsorption resin column is communicated with a first ethanol tank, an outlet of the first macroporous adsorption resin column is communicated with a first concentration tank, and a lower outlet of the first concentration tank is communicated with a first dryer; and an outlet of the first dryer is communicated with a first glucosyl stevioside tank. And the residual substrate is converted into stevioside with relatively better taste, so that the taste and quality of the product are improved.
