The main flavor substances of traditional meat products were reviewed in this paper. And the effect of nitrite on the flavor of low-temperature sausage was studied as an example. The flavor characteristic of meat products with nitrite addition was analyzed. It indicated that several new flavor compounds were detected in the nitrite-added sausage, and cured-meat flavor of meat products was enhanced by nitrite additions. New flavor compounds found in this research might be one of reasons for nitrite affecting meat products’flavor.
