Steviol Glycoside was proposed to be added as a Nonnutritive Sweetener in the food products and this was discussed in the 16th Authority meeting of FSSAI. FSSAI had issued a notification in this regard on 23rd March, 2015 through a draft regulation. FSSAI has considered the draft regulation and has amended the existing regulations which will now be called as FSS (Food Products Standards & Food Additives)(Amendment) Regulations, 2015. Under the new amendment in the FSSR, Steviol Glycoside is permitted to be used as a non-nutritive sweetener in particular food products within the maximum levels as defined under the amended regulations.
In present regulation of 3.1.3 for artificial sweetener, the related thereto is to be added after going through sub regulation (5): The below table reads as-
(6) Usage of nonnutritive sweetener – The present nonnutritive sweetener, as provided in column (2) of the given table is to be used in various food articles, as presented in Column (3). The quantities are mentioned and not likely to exceed the limit, as portrayed in column (4), according to the guidelines, mentioned in the regulation.
Moreover, Steviol Glycoside is likely to be marketed as present table top sweetener in powder, tablet or, in liquid format. It might comprise of 7 mgs as Steviol, if placed equivalent on 100 mg with filler or carrier. This point is mentioned in the 2nd proviso of the Explanation II, as related to sub-regulation (1) of regulation 3.1.3.
FSSAI notification further says:
Steviol Glycoside: This component is known for its light yellow or white powder with odorless characteristic. It is considered to be nearly 200 to 300 times sweeter, when compared with sucrose. This product is mainly procured from leaves of the stevia rebaudiana bertoni and the juice is extracted by using the hot water strategy. The extracted aqueous is passed from the absorption resin, which helps in trapping and concentrating the component.
The final resin is then washed off with the help of a solvent alcohol in order to release glycosides and recrystallized from aqueous ethanol or methanol. For purification procedure, ion exchange resins might be used, with final product spray. Rebaudioside A and Stevioside are some of the major components used. Associated options are rebaudioside D, B, C, F and dulcoside A.
Synonyms: INS no.960.
