SCL forms include SCL crystals, stable even at high temperatures, freeze-dried SCL, and a

Blends of SCL with polyols have been made by Tate and Lyle Technology for addition into
beverages or sugar-free chewing gums. McNeil Nutritionals, LLC, made a blend of SCL with
S.  rebaudiana Bertoni. In that case, SCL is used to mask the licorice off lavor associated with
somestevia extracts.

Licorice and licorice derivatives, including ammoniated glycyrrhizin, are afirmed as GRAS
for use in foods by the FDA (21 CFR 184.1408) (FDA 2011). Regulations include speciications
