Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
76 words
Flavorant capsules having a particle size of from 250 μm to 3.5 μm comprising a continuous hardened, impervious shell of edible protein material, carbohydrate material or a combination of protein and carbohydrate material having a wall thickness of from about 20 μm to 400 μm and having impregnated therein a flavor and/or aroma essence, derived from a frozen aqueous solution of the flavor and/or aroma essence, surrounding a hollow core empty of flavor and/or aroma essence.
Claim 2
Dependent Claim
76 words
Flavorant capsules having a particle size of from 250 μm to 3.5 μm comprising a continuous hardened, impervious shell of edible protein material, carbohydrate material or a combination of protein and carbohydrate material having a wall thickness of from about 20 μm to 400 μm and having impregnated therein a flavor and/or aroma essence, derived from a frozen aqueous solution of the flavor and/or aroma essence, surrounding a hollow core empty of flavor and/or aroma essence.
Claim 3
Dependent Claim
173 words
Flavorant capsules produced by a process which comprises: (a) adding particulated frozen aqueous flavor and/or aroma essence solution to a powdered wall material, having a particle size of from 60 μm to 150 μm, in a ratio of from 1:4 to 1:50 by weight of particulated frozen aqueous essence solution to powdered wall material, said wall material being selected from the group consisting of edible proteins, carbohydrates and combinations thereof, and forming by agitation at ambient temperature a continuous coating layer of the wall material on the frozen aqueous essence solution and allowing a water flux from the frozen aqueous essence particle to the surrounding wall material; (b) curing the coated particles by continuing agitation until the water flux ceases such that the wall thickness is from about 20 μm to 400 μm surrounding a hollow core and such that the aqueous flavor and/or aroma essence solution is impregnated within the wall material; and then (c) collecting the capsules having a particle size in the range of from 250 μm and 3.5 μm.
Claim 4
