ABSTRACT:
The present invention provides a method for fixing volatiles in an extruded glass substrate. A minor component consisting of a low molecular weight water-soluble carbohydrate or food acid is dry-blended with a major component consisting of a high molecular weight water-soluble polymeric carbohydrate in a ratio of from 10% to 30% low molecular weight carbohydrate or adipic, malic or citric acids or combinations thereof to at least 70% high molecular weight material. A volatile flavorant like orange oil or acetaldehyde is combined with this substrate mixture. The dry-blended admixture is extruded so that the temperature of the material in the extruder is at or above the melting point of the minor ingredient and above the glass transition state of the substrate. The free-flowing powder is relatively non-hygroscopic and possesses a high fix.
