Abstract
Abstract A method is provided for curing fresh primal cuts of meat intended for consumption by those on a low sodium diet which includes the step of subjecting a fresh primal cut to an aqueous curing solution substantially free of (a) organic nitrites and (b) chloride, phosphate, nitrate and sodium ions and containing from about 0.005 to about 0.40 percent by weight of a nitrite selected from the group consisting of potassium nitrite, ammonium nitrite, nitrous acid and mixtures thereof.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
127 words
In a method for curing fresh primal cuts of meat intended for consumption by those on a low sodium diet which does not require the presence of phosphate, chloride, nitrate or sodium ions, the step consisting essentially of: injecting an aqueous curing solution into a fresh primal cut in an amount corresponding to about 1.0 to about 20% of the weight of said primal cut, said curing solution being free of (a) organic nitrites (b) phosphate, chloride, nitrate and sodium ions except for the nominal present in commercial water supplies used in making up the solution; and said curing solution containing from about 0.005 to about 0.40% by weight of a nitrite selected from the group consisting of potassium nitrite, ammonium nitrite, nitrous acid and mixtures thereof.
Claim 2
Dependent Claim
127 words
In a method for curing fresh primal cuts of meat intended for consumption by those on a low sodium diet which does not require the presence of phosphate, chloride, nitrate or sodium ions, the step consisting essentially of: injecting an aqueous curing solution into a fresh primal cut in an amount corresponding to about 1.0 to about 20% of the weight of said primal cut, said curing solution being free of (a) organic nitrites (b) phosphate, chloride, nitrate and sodium ions except for the nominal present in commercial water supplies used in making up the solution; and said curing solution containing from about 0.005 to about 0.40% by weight of a nitrite selected from the group consisting of potassium nitrite, ammonium nitrite, nitrous acid and mixtures thereof.
Claim 3
Dependent Claim
25 words
The method of claim 1 wherein the concentration of the nitrite in the aqueous curing solution is from about 0.05 to about 0.25% by weight.
Claim 4
Dependent Claim
50 words
The method of claim 1 wherein the aqueous curing solution also contains from about 0.1 to about 0.9% by weight of a member selected from the group consisting of ascorbic acid, erythorbic acid, potassium salts of ascorbic and erythorbic acids, ammonium salts of ascorbic and erythorbic acids and mixtures thereof.
Claim 5
Dependent Claim
21 words
The method of claim 2 wherein the aqueous solution also contains from about 1 to about 8% by weight of sugar.
Claim 6
Dependent Claim
28 words
The method of claim 4 wherein the primal cut is at a temperature between about 33° and about 100° F. during the injection of the aqueous curing solution.
Claim 7
Dependent Claim
11 words
The method of claim 1 wherein the nitrite is potassium nitrite.
Claim 8
Dependent Claim
11 words
The method of claim 1 wherein the nitrite is ammonium nitrite.
Claim 9
Dependent Claim
11 words
The method of claim 1 wherein the nitrite is nitrous acid.
Claim 10
Dependent Claim
144 words
In a method for curing fresh primal cuts of meat intended for consumption by those on a low sodium diet which does not require the presence of phosphate, chloride, nitrate or sodium ions, the step consisting essentially of subjecting a fresh primal cut to an aqueous curing solution containing about: 0.005 to 0.40% by weight of a nitrite selected from the group consisting of potassium nitrite, ammonium nitrite, nitrous acid and mixtures thereof; 0.1 to 0.9% by weight of a member selected from the group consisting of ascorbic acid, erythorbic acid, potassium and ammonium salts of ascorbic and erythorbic acids, and mixtures thereof; and 1 to 8% by weight of sugar; said curing solution being free of (a) organic nitrites and (b) phosphate, chloride, nitrate and sodium ions except for the nominal amount present in commercial water supplies used in making up the solution.
