Abstract In this experiment, fermented sausage was produced from commercial lean pork and pork backfat (8:2, m/m)
with the addition of seasoning materials and Moringa powder using a mixed starter culture (WBL-45, from Italian
Sacco) of Staphylococcus carnosus, Staphylococcus xylosus and Lactobacillus sakei. The effect of Moringa powder on
physicochemical properties and N-nitrosamine contents of fermented sausage was investigated. Five groups were designed,
namely CK group (with no added sodium nitrate, VC, VE or Moringa powder), SN group (with 0.3 g/kg of sodium nitrate
added), VC group (with 0.3 g/kg of sodium nitrate and 0.5 g/kg of VC), VE group (with 0.3 g/kg of sodium nitrate and
0.2 g/kg of VE), and Moringa powder group (with 14.53 g/kg of Moringa powder added, which contained 0.3 g/kg sodium
nitrate). On days 0, 1, 4, 7 and 15 of ripening and after storage for 0, 1, 2 and 3 weeks, samples were collected to measure
water activity (aw), a* value, peroxide value (POV), nitrite content and N-nitrosamine contents. The results showed that the
samples from the Moringa group had a unique bright green color and a unique flavor and exhibited no significant differences
in aw, nitrite content or POV value compared with those from the VC and VE groups (P > 0.05). In addition, N-nitrosamine
contents were lower compared with the VC and VE groups.
