Reb-A 97% and Reb-A 98% are the most popular stevia products, it is widely used in beverage and foods.
Stevia rebaudiana leaves contain sweetening diterpene glycosides, known as steviol glycosides, which constitute 4–20% of the dry leaf weight (Ferrazzano et al., 2015). The leaf extracts are complex mixtures comprised of steviol glycosides (stevioside, Reb A, Reb B, Reb C, Reb D, Reb E, Reb F, dulcoside A, rubusoside, steviolbioside), labdane-type diterpenes, triterpenoids, steroids, volatile oils, and flavonoids. Stevioside and Reb A are the predominant steviol glycosides found in leaves of S. rebaudiana. Compared to stevioside, Reb A is considered more suitable for use to sweeten foods and beverages due to its less bitter aftertaste and greater solubility in water. Reb A is non-nutritive and tastes approximately 200-300 times sweeter than sucrose.
Several studies have suggested that in addition to their sweetness, steviosides and their related compounds, including rebaudioside A and isosteviol, may offer additional therapeutic benefits. These benefits include anti-hyperglycemic, anti-hypertensive, anti-inflammatory, anti-tumor, anti-diarrheal, diuretic, and immunomodulatory actions (Ferrazzano et al., 2015). In addition, steviol glycosides are known to have antioxidant activities (Bender et al., 2015).
