The compositions and methods can control microbial growth in aqueous streams used for transporting or processing food products.
Claims3
A method of limiting cross contamination of produce in flume water comprising:
- administering an antimicrobial concentrate composition to the flume water, the antimicrobial concentrate composition comprising:
- about 35 to about 45 weight-% acetic acid,
- about 5 to about 15 weight-% octanoic acid,
- about 3 to about 8 weight-% hydrogen peroxide,
- about 8 to about 16 weight-% peroxyacetic acid, and
- about 1 to about 5 weight-% peroxyoctanoic acid,
- wherein the composition is free of a chelating agent and a coupling agent, the composition has a pH of 1, and the total peracid concentration in the flume water is less than 39 ppm.
