Application of protective cultures in cold-smoked salmon containing salt substitutes (follow-up of fish reformulation project)
Project
Project code: MRI-MF-08-176 - 1050 Fisch-Reformulierungsprojekt
Contract period: 01.04.2018
- 01.03.2020
Purpose of research: Experimental development
The project investigates the effects of selected protective cultures (lactic acid bacteria) on the growth of Listeria innocua as a surrogate marker for Listeria monocytogenes in cold-smoked salmon containing salt substitutes. The aim is to evaluate the applicability of using protective cultures in combination with salt substitutes in order to improve the shelf life of sodium-reduced cold-smoked salmon. Lactic acid bacteria exert their preservative effects not only via the formation of lactate, but also via other antimicrobial substances such as bacteriocins. In the project, sterilized bacteriocin containing culture media will also be applied in order to suppress the growth of Listeria innocua. The efficacy of active cultures will be compared to the sterilized bacteriocin containing culture media. Furthermore, methods will be tested that can detect and quantify the antilisterial activity of the bacteriocin containing culture media.
