DESCRIPTION

Rosemary Extract may occur as a powder or a liquid. It is prepared by extraction from the leaves of Rosmarinus officinalis, using food grade acetone, ethanol, hexane, or a combination of hexane and ethanol (in a two-step process) as extraction solvents. It may also be extracted using supercritical carbon dioxide. Subsequent production steps may include filtration, purification, solvent evaporation, drying and sieving. Rosemary Extract may be deodorized, decolorized, and standardized using diluents and carriers permitted for use in foods. It is composed primarily of phenolic acids, flavonoids, diterpenes, diterpenoids, and triterpenes, and is characterized by the content of carnosic acid and carnosol. Rosemary Extract is insoluble in water.
