Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
49 words
In a process for processing an animal meat comprising the steps of scalding and chilling said animal meat, the improvement comprising contacting said animal meat with an aqueous bactericide comprising a mixture of two or more organic acids and a surfactant during both of said scalding and chilling steps.
Claim 2
Dependent Claim
49 words
In a process for processing an animal meat comprising the steps of scalding and chilling said animal meat, the improvement comprising contacting said animal meat with an aqueous bactericide comprising a mixture of two or more organic acids and a surfactant during both of said scalding and chilling steps.
Claim 3
Dependent Claim
