1. A method of controlling microbial growth in an aqueous stream used for transporting food products comprising the step of treating said aqueous stream with(i) from about 5 to 100 ppm of a percarboxylic acid selected from the group consisting of peracetic, peroctanoic, perdecanoic, and mixtures thereof;
- and(ii) from about 5 ppm to 500 ppm of hydrogen peroxide.

Abstract
The invention is a process for preventing microbial growth in aqueous streams by applying peracetic acid to the aqueous stream. Generally, the process of the invention is applicable to aqueous streams used in any number of applications such as the application of streams for the transport of fruits or vegetables into the processing environment and through the various steps of processing.

4. A method of controlling microbial growth in an aqueous stream used for transporting food products by administering an antimicrobial composition to said stream, said antimicrobial composition comprising:
-
(i) from about 5 to 100 ppm of a percarboxylic acid selected from the group consisting of peracetic, peroctanoic, perdecanoic, and mixtures thereof initially in the aqueous stream; and (ii) from about 5 to 500 ppm hydrogen peroxide initially in the aqueous stream, said method comprising the steps of (a) forming said antimicrobial composition by combining a first concentrate comprising hydrogen peroxide and a second concentrate selected from the group consisting of acetic, octanoic, decanoic, and mixtures thereof; and (b) administering said antimicrobial composition to said aqueous stream used for transporting products. - View Dependent Claims (5, 6, 7)
