Abstract
The present invention provides a method for fixing and/or preserving labile materials, especially food materials, in an extruded glassy substrate. A minor component containing of a high molecular weight water-soluble polymeric carbohydrate is dry-blended with a major component comprising of a low molecular weight water-soluble carbohydrate, sugar alcohol or food acid. Typically, the carbohydrate admixture comprises between about 15% to 40% high molecular weight carbohydrate material and at least about 40% low molecular weight carbohydrate, sugar alcohols or adipic, malic or citric acids or combinations thereof. A labile material like omega-3 oils or .beta.-carotene is combined with this substrate mixture. The dry-blended admixture is extruded so that the temperature of the material in the extruder is between about the glass transition state of the substrate and the melting point of the major ingredient. The free-flowing product is relatively non-hygroscopic and has a high fix.
