PERSTORP, SWEDEN: Towards the end of 2017, the European Union denied the authorization of formaldehyde as a preservative and hygiene condition enhancer. Foreseeing this decision, Perstorp has been researching the mode of action and effectiveness of organic acids against Salmonella for years.
New data brought to light that propionic acid reduces the motility of Salmonella and that specifically selected essential oils have a synergetic effect with organic acids. A new range of ProPhorce SA products puts these new insights to optimal use.
Formic acid is well known for its antibacterial properties and has been used to combat pathogens for years. In a new development, research at the faculty of veterinary medicine at the Utrecht University in the Netherlands showed that propionic acid also has an antibacterial effect that works synergistically to that of formic acid.
Where earlier trials have shown that some essential oils can allow formic acid to pass the cell wall and neutralize Salmonella, researchers now found that propionic acid effects on the motility of bacteria by stripping them of their flagella. This takes away the mobility of the pathogen and as such renders it harmless. The trials executed at the University of Utrecht also show a clear synergy between all of these components where the efficacy of the combination is much higher than the sum of its parts or of other organic acid solutions that were tested.
