Kinetic Analysis of Trasglycosylation Reaction of Stevioside Using Raw Starch as a Glycosy Donor

Abstract
|
|
|
|
Kinetic equations for transglycosylation of stevioside in the attrition coupled reaction system using raw starch as a glycosyl donor were derived considering that the reaction was carried out through two steps; production of cyclodextrin(CD) from raw starch in the attrition coupled reaction system, and then transglycosylation of glycosyl residues to stevioside from produced CD. Kinetic constants of derived equation were evaluated. ´Me simulation result showed that the derived kinetic equations could predict the experimental data reasonably well, and that can be utilized for optimization and scale-up of transglycosylation reactor and process developments.
