Production of rubusoside from high concentration of stevioside with or without rebaudioside A and its performance in micelle solubilization

, 2021
Rubusoside is a natural botanic sweetener with capacity of micelle solubilization. This study revealed the reaction pathway of enzymatically producing rubusoside from a high concentration of stevioside in the absence or presence of rebaudioside A, the ...

Heterologous expression of EUGT11 from Oryza sativa in Pichia pastoris for highly efficient one-pot production of rebaudioside D from rebaudioside A

International Journal of Biological Macromolecules, 2020
Rebaudioside D is a promising sweetener due to its zero calorie and high sweetness. Here, a transglucosylase gene eugt11 from Oryza sativa was for the first time expressed in Pichia pastoris, and transformant XE-3 showed the highest expression levels in pH 5.5 BMMY media containing 0.75% methanol.

Konsumentenakzeptanz von ausgewählten Erfrischungsgetränten mit Rebaudiosid A-

2011
Since the consumption of sugar-containing soft drinks is considered as a possible cause of obesity and diabetes, health-conscious consumers are resorting increasingly to low-calorie products, in which the sugar is replaced by artificial sweeteners. Rebaudioside A (RA), the main component of the plant Stevia rebaudiana, is a non-caloric sweetener of ...

NMR studies of the conformation of the natural sweetener rebaudioside A

Carbohydrate Research, 2009
Rebaudioside A is a natural sweetener from Stevia rebaudiana in which four beta-D-glucopyranose units are attached to the aglycone steviol. Its (1)H and (13)C NMR spectra in pyridine-d(5) were assigned using 1D and 2D methods. Constrained molecular dynamics of solvated rebaudioside using NMR constraints derived from ROESY cross peaks yielded the ...

Investigations on the Stability of Stevioside and Rebaudioside A in Soft Drinks

Journal of Agricultural and Food Chemistry, 2010
The stability of the two steviol glycosides stevioside and rebaudioside A and the possible formation of the aglycon steviol in different soft drinks were analyzed in samples spiked with stevioside or rebaudioside A after 24, 48, and 72 h storage times at 80 °C.

Production of Rebaudioside A from Stevioside Catalyzed by the Engineered Saccharomyces cerevisiae

Applied Biochemistry and Biotechnology, 2016
Rebaudioside A has superior taste quality among the steviol glycosides extracted from Stevia rebaudiana leaves. Given its high purity as a general-purpose sweetener, rebaudioside A has received significant attention and has been widely applied in food and beverages in recent decades.

Flavourprofil eines mit Rebaudiosid A optimierten, zuckerreduzierten Zitrone-Erfrischungsgetränkes

2012
Weight problems, such as obesity and overweight, with its associated complications are described as the main worldwide threat to human health of the 21st century. In the fight against those health conditions and also because of the rising health concerns of the population, low calorie and sugar-free products become more important to health aware ...
