The Preparation of High Purity of Rebaudioside A and Stevioside and the Enrichment of Rebaudioside C by Subsequent Twice Crystallizations from Natural Stevia Resources

open access: yesSeparations, 2021
A comprehensive utilization of rebaudioside A (RA), stevioside (ST), and rebaudioside C (RC) from natural stevia resources was proposed. The influence of the solvent, solvent concentration, solid-liquid ratio, temperature, and time on the purity and ...

Catalytic Hydrogenation of the Sweet Principles of Stevia rebaudiana, Rebaudioside B, Rebaudioside C, and Rebaudioside D and Sensory Evaluation of Their Reduced Derivatives [PDF]

open access: yesInternational Journal of Molecular Sciences, 2012
Catalytic hydrogenation of rebaudioside B, rebaudioside C, and rebaudioside D; the three ent-kaurane diterpene glycosides isolated from Stevia rebaudiana was carried out using Pd(OH)2. Reduction of steviol glycosides was performed using straightforward synthetic chemistry with the catalyst Pd(OH)2 and structures of the corresponding dihydro derivatives

Two-Step Enzymatic Conversion of Rebaudioside A into a Mono-α-1,4-Glucosylated Rebaudioside A Derivative

open access: yesJournal of Agricultural and Food Chemistry, 2021
A new two-step enzymatic conversion process for the production of a novel mono-α-1,4-glucosylated rebaudioside A derivative (RA1G) was established via transglycosylation followed by hydrolyzation. In the transglycosylation reaction catalyzed by cyclodextrin glycosyltransferase, rebaudioside A (RA) was converted into glucosylated RA derivatives (RAGs ...

Sucrose-replacement by rebaudioside a in a model beverage [PDF]

open access: yesJournal of Food Science and Technology, 2014
Rebaudioside A (RA), a component of Stevia rebaudiana, is a non-caloric sweetener of natural origin, suitable to meet consumers' demand for sweet taste, but undesirable flavors were reported at high concentrations. Aim of this study was to create a model beverage (ice-tea) in which sucrose was replaced increasingly by RA to identify optimal sensory ...

Mutation of Stevia glycosyltransferase UGT76G1 for efficient biotransformation of rebaudioside E into rebaudioside M

open access: yesJournal of Functional Foods, 2022
Rebaudioside M (RebM) is a desired natural non-caloric and high potency sweetener with very low content in the leaves of Stevia rebaudiana. In this study, based on the crystal structure of UDP-dependent glycosyltransferase UGT76G1, a key enzyme responsible for RebM production in S.

Rebaudioside A from Stevia rebaudiana stimulates GLP-1 release by enteroendocrine cells via bitter taste signalling pathways.

open access: yesFood & Function, 2023
Glucagon-like peptide 1 (GLP-1) is a multifaceted intestinal hormone with diverse physiological functions throughout the body. Previously, we demonstrated that the steviol glycoside rebaudioside A (rebA) from Stevia rebaudiana stimulates the release of ...

Efficient Bioconversion of Stevioside and Rebaudioside A to Glucosylated Steviol Glycosides Using an Alkalihalobacillus oshimesis-Derived Cyclodextrin Glucanotransferase

open access: yesMolecules, 2023
The enzymatic transglycosylation of steviol glycosides can improve the edulcorant quality of steviol glycosides. Cyclodextrin glucanotransferase (CGTase) is one of the most popular glucanotransferases applied in this reaction.

Production of rebaudioside D from stevioside using a UGTSL2 Asn358Phe mutant in a multi‐enzyme system

open access: yesMicrobial Biotechnology, 2020
Summary Rebaudioside D is a sweetener from Stevia rebaudiana with superior sweetness and organoleptic properties, but its production is limited by its minute abundance in S. rebaudiana leaves.
