High amounts of total phenolic content (1708.15 +/- 93.28 mg GAE/L) and carboxylic acids, which comprised 74.89% of the total volatiles, were found in the postbiotics. On day 0, the postbiotic-chitosan combinations decreased the E. coli O157:H7, L. monocytogenes and S. Typhimurium counts ranging from 1.58 to 3.21 log(10) compared to the control in frankfurters (P < 0.05). Total viable count and number of lactic acid bacteria were effectively reduced in all treatment groups (P < 0.05), and postbiotic and chitosan treatments did not cause any changes in pH and color of the frankfurters. In conclusion, postbiotic-chitosan combinations can be used to reduce the risks that might be associated with E. coli O157:H7, L. monocytogenes, and S. Typhimurium in frankfurters.eninfo:eu-repo/semantics/closedAccessFrankfurterPostbioticCharacterizationChitosanAntimicrobial effectChemical qualityArticle1883527897310.1016/j.meatsci.2022.1087862-s2.0-85125886308Q1WOS:000792912300016Q1
