| 摘要 |
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 mixture is extruded at a temperature which is essentially at or below the melting point of the minor ingredient but above the glass transition state of the substrate. The free-flowing powder is relatively non-hygroscopic and possesses a high fix. |
