Disclosed are encapsulating methods and encapsulated products. A payload material may be encapsulated within a wall material. The carrier material and payload material form a combination that is at least substantially solid at room temperature but that is sufficiently fluid at milling temperature to permit milling and subsequent encapsulation. The payload material may be, for instance, a bitter tasting material. In some embodiments, the microcapsules will serve a taste masking function. In other embodiments, the microcapsules may be used where a slow release of the payload material is desired.
1. An encapsulated product comprising:
a plurality of single wall microcapsules, each comprising a wall material, a payload material and carrier material, the payload material and carrier material forming a combination that is at least substantially solid at room temperature but that is sufficiently flowable at a milling temperature of 40-75° C. to permit milling and subsequent encapsulation within said wall material, said carrier material comprising a wax, said combination being disposed within the microcapsule single wall, said combination comprising a solution at said milling temperature, wherein said wall material is gelatin, said microcapsules exhibiting a 168-hour hexane extraction concentration of less than 2 mg/ml.
2. An encapsulated product according to claim 1 , said carrier material being selected from the group consisting of candelilla wax and paraffin wax.
3. An encapsulated product according to claim 1 , said payload material comprising an oil or an oil-soluble or -dispersible bioactive, pharmaceutical, or nutraceutical.
4. An encapsulated product according to claim 1 , said payload material comprising an oil selected from a volatile oil, a flavor oil, or an essential oil.
5. An encapsulated product according to claim 1 , said combination having a viscosity of 1200 centipoise or less at 75° C.
6. An encapsulated product according to claim 1 , said microcapsules exhibiting a 168-hour hexane extraction concentration of less than 1 mg/ml.
