In this study, cassia extracts were added to Harbin dry sausages. The nitrosamine content and related physicochemical properties, such as the pH value, nitrite residue content, peroxide value(POV), thiobarbituric acid(TBARS) content, and total volatile basic nitrogen(TVB-N) content in the sausages was determined 0, 2, 4, 6, 8, and 10 days after addition of extracts, byhigh performance liquid chromatography, in order to determine their relationship with the inhibition of nitrosamine production. The results o...
