| Rebaudioside A Usage And Synthesis |
| Description | Rebaudioside A is a natural non-caloric sweetener. It is one of the predominant steviol glycosides isolated from S. rebaudiana leaves. It increases glucagon-like peptide 1 (GLP-1) secretion in a 2-dimensional mouse intestine model. In a two bottle preference test, mice drink more water containing rebaudioside A than unsweetened water, though saccharin-sweetened water is still preferred. Rebaudioside A is metabolized by gut microbiota to steviol , a compound whose safety is widely studied. Consumption of rebaudioside A formulations by pre-diabetic patients did not increase fasting or 2 hour plasma glucose levels or insulin levels. | | Chemical Properties | White powder | | Uses | Rebaudioside A is a glycoside from the stevia plant. Rebaudioside A is used as a sweetener with sweetness about 300 times that of sugar with negligible effect on blood glucose. As a result, Rebaudiosi
de A is known for its application in treatment of many diseases like diabetes, high blood pressure and weight loss in some places. It is used as a food additive and in dietary supplements. | | Uses | natural sweetener to diabetics and others on carbohydrate-controlled diets | | Uses | Rebaudioside A is a natural, highly processed calorie free sweetener
obtained from the leaves of the plant stevia rebaudiana bertoni. it is
a steviol glycoside in which the steviol’s carboxyl and hydroxyl
hydrogen atom is replaced with glucose, it has three linked glucose
molecules at the hydroxyl site. rebaudiana (reb a) is 300–400 times
sweeter than sugar and the least bitter of the glycosides. it is ph and
heat stable with good solubility in water. uses include beverages,
table top sweetener, general foods. it is also termed reb a, stevia
extract, stevia. | | Definition | Rebaudioside A is a rebaudioside that is rubusoside in which the hydroxy groups at positions 3 and 4 of the beta-D-glucopyranosyloxy group at the 13alpha position have both been converted to the corresponding beta-D-glucopyranoside. It has a role as a sweetening agent. It is a beta-D-glucoside, a tetracyclic diterpenoid and a rebaudioside. It derives from a rubusoside and a beta-D-Glcp-(1->2)-[beta-D-Glcp-(1->3)]-beta-D-Glcp. | | benefits | Zero caloriesNo carbohydrateDoes not raise blood glucose or insulin levels (Zero Index Glycemic), safe for people with diabetesKeto, Vegan, and Gluten-Free | | Biological Activity | Rebaudioside A is a natural non-caloric sweetener.

Rebaudioside A is metabolized by gut microbiota to steviol, a compound whose safety is widely studied. Consumption of rebaudioside A formulations by pre-diabetic patients did not increase fasting or 2 hour plasma glucose levels or insulin levels. | | Safety | High-purity (95% minimum) of individual or combined steviol glycosides can be considered as GRAS (Generally Recognized as Safe) by the FDA. For example, FDA had no questions regarding Guilin Layn's conclusion that its reb A (≥97% by weight (w/w)) is GRAS as a table top sweetener and as a general purpose sweetener in foods, excluding meat and poultry products and infant formulas.Its safety has also been approved by the EFSA, JECFA, FSANZ and other authorities. |
