Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
101 words
A composition of matter for coating and preserving food consisting essentially of a mixture of (a) lard (b) a second fat consisting essentially of tallow or of partially hydrogenated lard, and (c) a wetting agent to promote adhesion between the coating and the food said wetting agent comprising not more than 1% by weight of said mixture, the ratio of (a) to (b) being between approximately 30:70 and 50:50 and said mixture having the characteristic of forming an effective preservative coating at a temperature of approximately 85° F. (29.4° C.) when applied to food having a temperature below said coating temperature.
Claim 2
Dependent Claim
101 words
A composition of matter for coating and preserving food consisting essentially of a mixture of (a) lard (b) a second fat consisting essentially of tallow or of partially hydrogenated lard, and (c) a wetting agent to promote adhesion between the coating and the food said wetting agent comprising not more than 1% by weight of said mixture, the ratio of (a) to (b) being between approximately 30:70 and 50:50 and said mixture having the characteristic of forming an effective preservative coating at a temperature of approximately 85° F. (29.4° C.) when applied to food having a temperature below said coating temperature.
Claim 3
Dependent Claim
16 words
The composition of claim 1 further characterized in that the wetting agent consists essentially of lecithin.
Claim 4
Dependent Claim
32 words
The composition of claim 2 further characterized in that the preferred ratio of said lard to said second fat is approximately 40:60 and said lecithin does not exceed 1% of said mixture.
Claim 5
Independent Claim
136 words
A method of preserving foods consisting essentially of (1) mixing lard, a second fat consisting essentially of tallow or of partially hydrogenated lard and a wetting agent, said mixture consisting essentially of 30%-50% by weight lard, 50%-70% by weight said second fat and not more than 1% by weight of a wetting agent, (2) heating said mixture to a temperature sufficient to liquefy the ingredients thereof, (3) adjusting said mixture to a temperature of approximately 85° F. (29.4° C.) and coating a food with said mixture to provide a generally uniform continuous coating said food having an interior temperature lower than 85° F. (29.4° C.), (4) allowing said coating to cool sufficiently to harden to withstand major deformation upon handling, and (5) maintaining said coated food in a chilled environment substantially throughout a period of storage.
Claim 6
Independent Claim
136 words
A method of preserving foods consisting essentially of (1) mixing lard, a second fat consisting essentially of tallow or of partially hydrogenated lard and a wetting agent, said mixture consisting essentially of 30%-50% by weight lard, 50%-70% by weight said second fat and not more than 1% by weight of a wetting agent, (2) heating said mixture to a temperature sufficient to liquefy the ingredients thereof, (3) adjusting said mixture to a temperature of approximately 85° F. (29.4° C.) and coating a food with said mixture to provide a generally uniform continuous coating said food having an interior temperature lower than 85° F. (29.4° C.), (4) allowing said coating to cool sufficiently to harden to withstand major deformation upon handling, and (5) maintaining said coated food in a chilled environment substantially throughout a period of storage.
Claim 7
Dependent Claim
16 words
The method of claim 4 further characterized in that the wetting agent consists essentially of lecithin.
Claim 8
Dependent Claim
24 words
A method of claim 4 further characterized in that the storage environment for the coated food is not higher than 40° F. (4.4° C.).
Claim 9
Independent Claim
96 words
A method of preserving foods consisting essentially of (1) mixing lard, a second fat consisting essentially of tallow or of partially hydrogenated lard and lecithin, the ratios of lard, said second fat, and lecithin being between 30:70:1 and 50:50:1, (2) melting said mixture and adjusting it to approximately 85° F. (29.4° C.), (3) thoroughly coating said food with said mixture, (4) allowing said coating to harden on said food until said coating will withstand normal handling, and (5) maintaining said coated food throughout a storage period in an environment not warmer than 40° F. (4.4° C.).
Claim 10
Independent Claim
96 words
A method of preserving foods consisting essentially of (1) mixing lard, a second fat consisting essentially of tallow or of partially hydrogenated lard and lecithin, the ratios of lard, said second fat, and lecithin being between 30:70:1 and 50:50:1, (2) melting said mixture and adjusting it to approximately 85° F. (29.4° C.), (3) thoroughly coating said food with said mixture, (4) allowing said coating to harden on said food until said coating will withstand normal handling, and (5) maintaining said coated food throughout a storage period in an environment not warmer than 40° F. (4.4° C.).
Claim 11
Dependent Claim
29 words
The method of claim 7 further characterized in that the preferred ratio of the ingredients of said mixture consists essentially of approximately 40% lard, 60% tallow and 1% lecithin.
Claim 12
Dependent Claim
46 words
The method of claim 7 further characterized in that prior to being coated with said mixture the food is maintained at a generally uniform temperature slightly greater than the temperature at which said food freezes or at which said food may be injured by excessive chilling.
Claim 13
Dependent Claim
41 words
The method of claim 9 wherein the food consists essentially of a meat or meat product and the temperature of said meat or meat product at the time of coating is between 27° F. (-2.8° C.) and 30° F. (-1.1° C.).
