It is a good dietary supplement, being non-calorific, thermally stable, non-toxic, with a sugar-like taste profile, and suitable for diabetics, phenylketonuria patients and the obese. It is also non-fermentable, and exhibits anti-carcinogenic, antioxidant and anti-hyperglycemic properties. Stevioside tastes about 300 times sweeter than 0.4% sucrose solution. Thus, it offers a reasonably rare combination of health Nonnutritive sweetenersSweetenersNonnutritive sweeteners.Sweeteners.664/.5De Sirshendu767857Mondal Sourav767855Banerjee Suvrajit1700640MiAaPQMiAaPQMiAaPQBOOK9910821464803321Stevioside4083786UNINA
