Definitions

  • a disinfectant composition for reducing microbial contaminants on direct and indirect food contact surfaces demonstrates a synergistic disinfection mechanism by combining the diffusion mechanism of a booster agent or additive and a peroxy acid. Also provided is a method of reducing microbial contaminants of a surface through the treatment, application, or deposition of the composition onto a substrate. Finally, provided is a method of using the composition for disinfecting substrates, for example those used in cold aseptic filling (CAF) applications.
  • CAF cold aseptic filling
  • Peracetic acid (PAA) and peroxycarboxylic acids are known for their use as antimicrobial agents.
  • conventional peroxycarboxylic acids have inherent disadvantages of limited storage stability, and water solubility.
  • peroxycarboxylic acids compositions are not effective if low concentrated and/or used at lower temperatures.
  • the processors use high concentration of chemicals like acetic acid or chlorine source. This often leads to concern on operator safety, compatibility issues with equipment and high cost.
  • CAF Cold-aseptic filling
  • Coffee processors prefer to produce through cold aseptic filling techniques which have minimum manual intervention have the advantage of long shelf life, keeping original flavor and nutrient of the products, saving packaging material cost compared to the conventional hot fill which can be sensitive to most of the plant based milk, cereal drinks and fruits juices.
  • Cold-aseptic filling CAF is now a widely used process that is consistently being adapted to new demands.
