Abstract
Abstract In the preparation of cured meat, curing is carried out under conditions such as to control the amount of free nitrite that remains in the cured meat, and at least the major proportion of the residual free nitrite is then destroyed without significantly affecting the cured colour by means of a substance that reacts with said residual free nitrite, said substance containing sulfur dioxide in combined form and being selected from the group consisting of alkali metal sulfites, bisulfites, and thiosulfates.
