Abstract
Abstract The formation of nitrosamines in cooked, cured meat products such as ham and bacon is reduced by a process in which the meat is injected with a curing solution containing nitrite and a food grade acid encapsulated with a coating material which melts at a temperature above 115 DEG F.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
195 words
A process for preparing cured ham or bacon so as to reduce the quantity of nitrosamines formed when the cured meat is subjected to frying temperatures, comprising the steps of injecting ham or bacon belly meat with a curing solution containing alkali metal nitrite and a sufficient amount of food grade acid encapsulated with a non-toxic coating material which melts at a temperature above 115° F., said acid being in an amount sufficient to provide a desired concentration in the meat to react with and substantially reduce or deplete the nitrite and being capable, in its encapsulated form, of causing reduction of nitrite concentration in said solution, holding the meat at a temperature below the melting point of said coating material for a period of time to permit the nitrite to exert its color-developing and anti-botulism effect on the meat, and thereafter processing the meat at a temperature sufficient to melt said coating material and thus release the acid into said meat in order for it to react with said injected nitrite, thereby reducing the amount of nitrite available for reaction with amines contained in the meat whereby the nitrosamine formation is reduced upon frying.
Claim 2
Dependent Claim
195 words
A process for preparing cured ham or bacon so as to reduce the quantity of nitrosamines formed when the cured meat is subjected to frying temperatures, comprising the steps of injecting ham or bacon belly meat with a curing solution containing alkali metal nitrite and a sufficient amount of food grade acid encapsulated with a non-toxic coating material which melts at a temperature above 115° F., said acid being in an amount sufficient to provide a desired concentration in the meat to react with and substantially reduce or deplete the nitrite and being capable, in its encapsulated form, of causing reduction of nitrite concentration in said solution, holding the meat at a temperature below the melting point of said coating material for a period of time to permit the nitrite to exert its color-developing and anti-botulism effect on the meat, and thereafter processing the meat at a temperature sufficient to melt said coating material and thus release the acid into said meat in order for it to react with said injected nitrite, thereby reducing the amount of nitrite available for reaction with amines contained in the meat whereby the nitrosamine formation is reduced upon frying.
Claim 3
Dependent Claim

The process of claim 1 wherein said food grade acid is lactic acid.
Claim 6
Dependent Claim
13 words
The process of claim 1 wherein said food grade acid is sorbic acid.
Claim 7
Dependent Claim
13 words

Claim 8
Dependent Claim
11 words
The process of claim 1 wherein said coating material comprises tallow.
Claim 9
Dependent Claim
21 words
The process of claim 1 wherein said encapsulated acid is in the form of capsules having diameters less than 1,000 microns.
Claim 10
Dependent Claim
16 words

Claim 11
Dependent Claim
16 words
The process of claim 1 wherein said coating material melts within the range of 120°-138° F.
Claim 12
Dependent Claim
35 words

Claim 13
Dependent Claim
16 words
The process of claim 11 wherein said concentration is about 800 to 1200 parts per million.
Claim 14
Dependent Claim
84 words
A meat curing composition for reducing the quantity of nitrosamines formed in ham or bacon, comprising an injectible meat curing solution containing nitrite and a food grade acid encapsulated with a non-toxic coating material which melts above 115° F., said acid being present in said solution in an amount sufficient to provide a concentration of at least 300 ppm in the meat, and said acid being further characterized as being capable, in its unencapsulated form, of causing reduction of nitrite concentration in said solution.
Claim 15
Dependent Claim
84 words
A meat curing composition for reducing the quantity of nitrosamines formed in ham or bacon, comprising an injectible meat curing solution containing nitrite and a food grade acid encapsulated with a non-toxic coating material which melts above 115° F., said acid being present in said solution in an amount sufficient to provide a concentration of at least 300 ppm in the meat, and said acid being further characterized as being capable, in its unencapsulated form, of causing reduction of nitrite concentration in said solution.
