Abstract
Stabilized peroxycarboxylic acid compositions are provided. The stable peroxycarboxylic acid compositions are particularly suitable for use in sanitizing equipment and surfaces to reduce yeasts, spores and bacteria, including those having contact with food, food products and/or components thereof, which require or benefit from infection control suitable for direct contact with such food sources are provided.
Claims16
A method of reducing a microbial population on a surface or substrate using a stabilized peroxycarboxylic acid composition comprising:
- providing a peroxycarboxylic acid composition comprising a C1-C22 carboxylic acid;
- a C1-C22 peroxycarboxylic acid;
- hydrogen peroxide, wherein the peroxycarboxylic acid and the hydrogen peroxide are in a weight ratio of from about 2:1 to about 100:1;
- and a pyridine carboxylic acid comprising nicotinic acid, wherein the composition does not include metal ions and does not include dipicolinic acid;
- and
- contacting the surface or substrate with a use solution of said composition for sufficient time to reduce the microbial population, wherein said use solution has a pH of or below about 4.
