Claim 13
Independent Claim
80 words
A method of inhibiting the production of enterotoxin from Clostridium botulinum and, upon cooking, inhibiting formation of nitrosamines from nitrite salt in corned beef and smoked poultry which comprises the step of adding thereto an alkali metal nitrite salt, in an amount less than about 120 ppm, and a compound selected from the group consisting of hypophosphorous acid and its nontoxic water-soluble salts in an amount effective to inhibit production of enterotoxin from Clostridium botulinum during storage of the meat.
