FOG' PROTECT Use of protective flora in pasteurized fatty livers [Ressourcing Carnot Qualiment project]

The use of protective flora in pasteurized fatty livers: an alternative to replacing nitrites?

Manufacturers in the fatty palmiped sector want to find new, more "natural" alternatives to the use of chemical preservatives while maintaining high food safety. This biopreservation project was therefore proposed to meet the needs of the sector: use alternatives to nitrites, secure fatty liver products against pathogenic bacteria and reduce the economic losses caused by spoilage bacteria.
The main objective of the project is to find biopreservation flora / metabolites to replace nitrites in pasteurized fatty livers. First, potentially protective strains will be selected (strains / molecules for sale and CTCPA collection strains). The safety of these strains / metabolites (absence of resistance to antibiotics and production of biogenic amines) will be evaluated in a laboratory environment. Only strains that do not show resistance and do not produce histamine will be studied for their antimicrobial efficacy on target strains in the laboratory environment. Among the target strains are strains of fatty liver damage such as Clostridium spp. and lactic acid bacteria as well as pathogenic strains such as Listeria monocytogenes and Clostridium botulinum like. About a hundred strains / metabolites with biopreservation potential will be studied against fifty target strains.
