Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
72 words
A composition for improving the shelf-life of fish fillet comprising: (a) from about 75 percent to about 90 percent alkali metal hexametaphosphate; (b) alkali metal acid pyrophosphate in an amount sufficient to provide a treatment solution having a pH within the range of from about 5.5 to about 6.5; and (c) a sorbate antimicrobial agent in a stabilizing effective amount; said percentages being based on the total dry weight of said composition.
Claim 2
Dependent Claim
72 words
A composition for improving the shelf-life of fish fillet comprising: (a) from about 75 percent to about 90 percent alkali metal hexametaphosphate; (b) alkali metal acid pyrophosphate in an amount sufficient to provide a treatment solution having a pH within the range of from about 5.5 to about 6.5; and (c) a sorbate antimicrobial agent in a stabilizing effective amount; said percentages being based on the total dry weight of said composition.
Claim 3
Dependent Claim
13 words
The composition of claim 1 wherein said alkali metal hexametaphosphate is sodium hexametaphosphate.
Claim 4
Dependent Claim
15 words
The composition of claim 1 wherein said alkali metal acid pyrophosphate is sodium acid pyrophosphate.
Claim 5
Dependent Claim
22 words
The composition of claim 1 wherein said antimicrobial agent is selected from the group consisting of sorbic acid and alkali metal sorbates.
Claim 6
Dependent Claim
14 words
The composition of claim 1 wherein said antimicrobial agent is an alkali metal sorbate.
Claim 7
Dependent Claim
11 words
The composition of claim 5 wherein said sorbate is potassium sorbate.
Claim 8
Dependent Claim
63 words
A fish fillet treating composition comprising from about 75 percent to about 90 percent sodium hexametaphosphate, from about 9 percent to about 11 percent sodium acid pyrophosphate and from about 4 percent to about 8.5 percent potassium sorbate, said sodium acid pyrophosphate being present in an amount sufficient to provide a treatment solution having a pH ranging from about 5.5 to about 6.5.
Claim 9
Dependent Claim
63 words
A fish fillet treating composition comprising from about 75 percent to about 90 percent sodium hexametaphosphate, from about 9 percent to about 11 percent sodium acid pyrophosphate and from about 4 percent to about 8.5 percent potassium sorbate, said sodium acid pyrophosphate being present in an amount sufficient to provide a treatment solution having a pH ranging from about 5.5 to about 6.5.
Claim 10
Dependent Claim
32 words
A method for treating fish fillet which comprises applying to the surface of the fillet an amount of the composition of claim 1 sufficient to improve the shelf-life of said fish fillet.
Claim 11
Dependent Claim
13 words
The method of claim 8 wherein said alkali metal hexametaphosphate is sodium hexametaphosphate.
Claim 12
Dependent Claim
15 words
The method of claim 8 wherein said alkali metal acid pyrophosphate is sodium acid pyrophosphate.
Claim 13
Dependent Claim
22 words
The method of claim 8 wherein said antimicrobial agent is selected from the group consisting of sorbic acid and alkali metal sorbates.
Claim 14
Dependent Claim
14 words
The method of claim 8 wherein said antimicrobial agent is an alkali metal sorbate.
Claim 15
Dependent Claim
11 words
The method of claim 12 wherein said sorbate is potassium sorbate.
