Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
103 words
A PROCESS OF MANUFACTURING A STABLE, SUBSTANTIALLY HOMOGENOUS EDIBLE MICROGLOBULE, COMPRISING THE STEPS OF: A. PROVIDING A CONTINUOUS-PHASE VEHICLE MATERIAL OF WATERIMMISCIBLE LIQUID; B. PROVIDING A DISCONTINUOUS PHASE OF SOLID MATERIAL AS DISCRETE, MINUTE PARTICLES, DISPERSED IN SAID CONTINUOUSPHASE VEHICLE MATERIAL, WHEREIN SAID DISCONTINUOUS-PHASE MATERIAL CONSISTS SUBSTANTIALLY OF HYDROPHILIC, POLYMERIC, CROSS-LINKAGE FILM FORMING MATERIAL AND OIL-INSOLUBLE PAYLOAD MATERIAL DISPERSED IN SAID FILM-FORMING MATERIAL; C. SUBSEQUENTLY ADDING A LIQUID WATER-SOLUBLE CROSS-LINKING AGENT, WITH AGITATION, TO THE DISPERSION OF DISCONTINUOUS-PHASE PARTICLES AND THE CONTINUOUS-PHASE VEHICLE TO HARDEN THE DISCONTINUOUS PHASE PARTICLES AND FORM STABLE, SUBSTANTIALLY HOMOGENEOUS MICROGLOBULES THEREOF OF ABOUT 1 TO 1000 MICRON SIZE.

Claim 3
Dependent Claim
99 words
The process of claim 1 wherein the dispersion of solid discontinuous-phase particles in the continuousphase vehicle is provided by A. Providing a liquid water-solution of a gellable polymeric material, having the payload material dispersed therein; B. Dispersing said water-solution of gellable polymeric material and said continuous-phase vehicle material while maintaining the liquid condition of the water solution of polymeric material; C. Altering the condition of said dispersion of the water-solution of gellable polymeric material to cause gellation of said water solution of polymeric material and thus give solid discrete particles of gelled discontinuousphase material dispersed in said continuous phase.
Claim 4
Dependent Claim
55 words
The process of claim 2 wherein said water solution of polymeric material is provided and maintained in liquid condition in steps (A) and (B) by being at a temperature above the gel temperature of said polymeric material and the altering of conditions in step (C) is effected by lowering the temperature below said gel temperature.
Claim 5
Dependent Claim
11 words
The process of claim 2 wherein said polymeric material is gelatin.
Claim 6
Dependent Claim
11 words
The process of claim 3 wherein said polymeric material is gelatin.
Claim 7
Dependent Claim
15 words
The process of claim 5 wherein the cross-linking agent is a water solution of glutaraldehyde.
Claim 8
Dependent Claim
11 words
The process of claim 1 wherein said polymeric material is gelatin.
Claim 9
Dependent Claim
15 words
The process of claim 1 wherein the cross-linking agent is a water solution of glutaraldehyde.
Claim 10
Dependent Claim
16 words
The process of claim 1 wherein the continuous-phase vehicle material includes a fluorocarbon liquid solvent material.
Claim 11
Dependent Claim
23 words
The process of claim 9 wherein the fluorocarbon solvent material is added to the continuous-phase vehicle material after the completion of step (C).
