Abstract
Abstract A coated food product of this invention is produced by applying an aqueous dispersion containing water soluble algin to the surface of a food substrate. The aqueous dispersion has a viscosity effective to substantially uniformly coat the surface of the food substrate. A dry gelling mixture is then applied to the align-coated food substrate for a period of time sufficient to form a substantially continuous edible alginate film along the surface of the food substrate. The film is sufficient to effectively retard the migration of moisture from the surface of the food substrate thereby retarding dehydration thereof. The film is sufficient to constitute an oxygen barrier for retarding oxidation of the food substrate and to retain flavor within said food substrate. The dry gelling mixture comprises a dry carrier material and a dry gelling agent. The carrier material and gelling agent are in particulate form and have particle sizes sufficient to obtain a substantially uniform gelling mixture.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
142 words
A process for coating food products comprising: (a) applying an aqueous dispersion containing water soluble algin to the surface of a food substrate, (b) the aqueous dispersion having a viscosity effective to substantially uniformly coat the surface of the food substrate, and then (c) applying a dry gelling mixture containing a calcium ion to the algin-coated food substrate for a period of time sufficient to form a substantially continuous edible alginate film along the surface of the food substrate, said particle gelling mixture having a particle size sufficient to obtain a uniform gelling mixture (d) said film being sufficient to effectively retard the migration of moisture from the surface of the food substrate thereby retarding dehydration thereof, (e) said film being sufficient to constitute an oxygen barrier for retarding oxidation of the food substrate and to retain flavor within said food substrate.
Claim 2
Dependent Claim
142 words
A process for coating food products comprising: (a) applying an aqueous dispersion containing water soluble algin to the surface of a food substrate, (b) the aqueous dispersion having a viscosity effective to substantially uniformly coat the surface of the food substrate, and then (c) applying a dry gelling mixture containing a calcium ion to the algin-coated food substrate for a period of time sufficient to form a substantially continuous edible alginate film along the surface of the food substrate, said particle gelling mixture having a particle size sufficient to obtain a uniform gelling mixture (d) said film being sufficient to effectively retard the migration of moisture from the surface of the food substrate thereby retarding dehydration thereof, (e) said film being sufficient to constitute an oxygen barrier for retarding oxidation of the food substrate and to retain flavor within said food substrate.
Claim 3
Dependent Claim
26 words
A process for coating food products as described in claim 1 wherein the dry gelling mixture comprises a dry carrier material and a dry gelling agent.
Claim 4
Dependent Claim
34 words
A process for coating food products as described in claim 2 wherein the carrier material and gelling agent are in particulate form and have particle sizes sufficient to obtain a substantially uniform gelling mixture.
Claim 5
Dependent Claim
35 words
A process for coating food products as described in claim 3 wherein the particulate gelling agent is calcium chloride or calcium lactate and has a particle size which blends with the particulate dry carrier material.

Claim 8
Dependent Claim
67 words
A process for coating food products as described in claim 2 wherein the dry gelling mixture has been produced by (a) dissolving a gelling agent to form a solution in a solvent material, (b) mixing the gelling agent solution with a dry carrier material and (c) evaporating the solvent material thereby leaving the dry gelling mixture as a residue of carrier material with gelling agent absorbed therein.
Claim 9
Dependent Claim
