Abstract A solid essential oil flavor composition having a high essential oil content and a process for preparing the product are disclosed, the process involving preparation of a heated or cooked aqueous mixture of a sugar and starch hydrolyzate together with an emulsifier. A selected essential oil or other oil-soluble flavor is combined and blended with a mixture in a closed vessel under controlled pressure conditions to form a homogeneous melt, the melt being extruded into a relatively cool solvent, dried and combined with a selected anticaking agent to produce the stable, relatively non-hygroscopic particulate flavor composition of the invention. The selected quantity of essential oil flavor blended into the homogeneous melt being sufficient to yield about 12 to 35% by weight of essential oil in the encapsulated solid particulate composition. During the process, encapsulation efficiency is maintained preferably at or above about 60%, more preferably above about 70% and most preferably above about 75 to 80%. Also, the cook temperature for the process is preferably maintained at or below a maximum of about 126 DEG C.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
173 words
A stable, melt-based and extruded solid essential oil composition in particulate form produced by the procees comprising the steps of: (a) forming an aqueous mixture of a sugar, a starch hydrolysate and an emulsifier and heating said mixture to approximately its boiling point but not greater than about 126° C. (b) combining and blending an essential oil flavor with said aqueous mixture by agitating said aqueous mixture and said essential oil flavor in a closed vessel under a pressure of about 7 to 50 psi to form a homogeneous melt; (c) extruding said homogeneous melt into a relatively cool solvent to form a solid extruded material; and (d) drying and combining said solid extruded material with an anti-caking agent to produce a stable and relatively non-hygroscopic particulate product having the character of extruded solid amorphous particles, the particles consisting of a sugar, starch hydrolysate, selected emulsifier, selected essential oil flavor and water, the essential oil flavor forming about 14 to 30% by weight of the essential oil flavor in substantially completely encapsulated form.
Claim 2
Dependent Claim
173 words
A stable, melt-based and extruded solid essential oil composition in particulate form produced by the procees comprising the steps of: (a) forming an aqueous mixture of a sugar, a starch hydrolysate and an emulsifier and heating said mixture to approximately its boiling point but not greater than about 126° C. (b) combining and blending an essential oil flavor with said aqueous mixture by agitating said aqueous mixture and said essential oil flavor in a closed vessel under a pressure of about 7 to 50 psi to form a homogeneous melt; (c) extruding said homogeneous melt into a relatively cool solvent to form a solid extruded material; and (d) drying and combining said solid extruded material with an anti-caking agent to produce a stable and relatively non-hygroscopic particulate product having the character of extruded solid amorphous particles, the particles consisting of a sugar, starch hydrolysate, selected emulsifier, selected essential oil flavor and water, the essential oil flavor forming about 14 to 30% by weight of the essential oil flavor in substantially completely encapsulated form.
