Abstract
Described are flavor composition, flavor component, perfume composition and perfume component-containing microparticles which are particulate matrices composed of:(a) an olfactorily active component (e.g., perfume component);(b) silica; and(c) a saccharide composition which is a mixture of mannitol and maltose.The microparticles are useful in augmenting, enhancing and/or imparting aroma and/or taste (over relatively long periods of time in a controllably releasable manner) to perfume compositions, perfumed articles (e.g., deodorancy and antiperspirant sticks), foodstuffs, chewing gums, beverages and the like. Also described is a process for preparing the above-mentioned microparticles using, in sequence, (1) adsorption of the olfactorily active material onto silica followed by (2) a blending/extrusion step followed by (3) at least one particularization step.
