Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
126 words
In a process for the production of a cured meat which comprises treating the meat with alkali metal nitrite under conditions such as to leave in the cured meat an excess of nitrite over that which reacts with the pigments of the meat, the improvement which consists in introducing into the meat a 1,2-dihydroquinoline of the general formula ##STR3## where R 1 , R 2 , R 3 and R 4 may be hydrogen or an alkyl group containing from 1 to 6 carbon atoms, and R 5 is an alkoxy group containing from 1 to 12 carbon atoms, said 1,2-dihydroquinoline being introduced in an amount effective to reduce the formation of carcinogenic nitrosamines from the excess nitrite when the cured meat is grilled or fried.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
25 words
A process according to claim 1, wherein the 1,2-dihydroquinoline introduced forms from about 5 to about 250 parts per 10 6 of the cured meat.
Claim 4
Dependent Claim
25 words
A process according to claim 2 wherein the 1,2-dihydroquinoline introduced forms from about 5 to about 100 parts per 10 6 of the cured meat.
Claim 5
Dependent Claim
45 words
A process according to claim 1, wherein R 1 , R 2 , R 3 and R 4 are hydrogen or an alkyl group containing from 1 to 4 carbon atoms, and R 5 is an alkoxy group containing from 1 to 4 carbon atoms.
Claim 6
Dependent Claim
11 words
A process according to claim 1, wherein the 1,2-dihydroquinoline is ethoxyquin.
Claim 7
Dependent Claim
84 words
A cured meat containing excess alkali metal nitrite in an amount up to about 200 parts per 10 6 of the meat, and containing per 10 6 of the meat from about 5 to 250 parts of a 1,2-dihydroquinoline of the general formula ##STR4## where R 1 , R 2 , R 3 and R 4 may be hydrogen or an alkyl group containing from 1 to 6 carbon atoms, and R 5 is an alkoxy group containing from 1 to 12 carbon atoms.
Claim 8
Dependent Claim
84 words
A cured meat containing excess alkali metal nitrite in an amount up to about 200 parts per 10 6 of the meat, and containing per 10 6 of the meat from about 5 to 250 parts of a 1,2-dihydroquinoline of the general formula ##STR4## where R 1 , R 2 , R 3 and R 4 may be hydrogen or an alkyl group containing from 1 to 6 carbon atoms, and R 5 is an alkoxy group containing from 1 to 12 carbon atoms.
Claim 9
Dependent Claim
46 words
A cured meat according to claim 6, wherein R 1 , R 2 , R 3 and R 4 are hydrogen or an alkyl group containing from 1 to 4 carbon atoms, and R 5 is an alkoxy group containing from 1 to 4 carbon atoms.
Claim 10
Dependent Claim
37 words
Bacon containing excess alkali metal nitrite in an amount up to about 200 parts per 10 6 of the bacon and containing from about 5 to about 100 parts of ethoxyquin per 10 6 of the bacon.
Claim 11
Dependent Claim
37 words
Bacon containing excess alkali metal nitrite in an amount up to about 200 parts per 10 6 of the bacon and containing from about 5 to about 100 parts of ethoxyquin per 10 6 of the bacon.
