Stevia (/ ˈ s t iː v i ə, ˈ s t ɛ v i ə /) [1] [2] is a sweet sugar substitute that is about 50 to 300 times sweeter than sugar. [3] It is extracted from the leaves of Stevia rebaudiana, a plant native to areas of Paraguay and Brazil. [4] [5] The active compounds in stevia are steviol glycosides (mainly stevioside and rebaudioside).
Stevia rebaudiana is a plant species in the genus Stevia of the family Asteraceae. It is commonly known as candyleaf, sweetleaf or sugarleaf. [1] [2] It is a small seasonal plant which grows to a height of 30–60 centimetres (1–2 feet). [2] It has elongated leaves that grow along the stems and are lined up against each other.
The species Stevia rebaudiana is widely grown for the sweet compounds (steviol glycosides) extracted from its leaves, sold as a sugar substitute under the generic name stevia and several trade names. [ 11 ]
Rebaudioside A (sometimes shortened to "Reb A") is a steviol glycoside from the leaves of Stevia rebaudiana that is 240 times sweeter than sugar. [2] Rebaudioside A is the sweetest and most stable steviol glycoside, and is less bitter than stevioside. [3] Stevia leaves contain 9.1% stevioside and 3.8% rebaudioside A. [3]
Rebiana is the trade name for high-purity rebaudioside A, a steviol glycoside that is 200 times as sweet as sugar. [1] It is derived from stevia leaves by steeping them in water and purifying the resultant extract to obtain the rebaudioside A. [1] The Coca-Cola Company filed patents on rebiana, and in 2007 it licensed the rights to the patents for food products to Cargill; Coca-Cola retained ...
Stevioside is the main sweetener (along with rebaudioside A) found in the leaves of Stevia rebaudiana, a plant originating in South America.Dried leaves, as well as aqueous extracts, have been used for decades as a sweetener in many countries, notably in Latin America and Asia (Japan, China). [3]
Truvia (also shown as truvía) is a brand of stevia-based sugar substitute developed jointly by The Coca-Cola Company and Cargill. It is distributed and marketed by Cargill as a tabletop sweetener as well as a food ingredient. [1] Truvia is made of stevia leaf extract, erythritol, and natural flavors.
Steviol glycosides do not induce a glycemic response when ingested, because humans cannot metabolize stevia. [ 4 ] [ 5 ] The acceptable daily intake (ADI) for steviol glycosides, expressed as steviol equivalents, has been established to be 4 mg/kg body weight/day, and is based on no observed effects of a 100 fold higher dose in a rat study.
