The present invention relates to compositions including peroxyacetic acid and peroxyoctanoic acid and methods for preventing microbial growth in aqueous streams including the step of applying a composition of the invention to the stream. The compositions and methods can control microbial growth in aqueous streams used for transporting or processing food products.

Method and composition for inhibition of microbial growth in aqueous food transport and process streams

Composition for inhibition of microbial growth

A method of using peracid/acid compositions, where the mole ratio of acid to peracid is less than about 3:1, to treat field or greenhouse grown plant tissue, seeds, fruits, and growing media and containers is described. The peracid/acid system can lower the natural, plant pathogen and human pathogenic microbial load resulting in less waste to molding, spoilage, and destruction because of pathogenic poisons.

Peroxy acid treatment to control pathogenic organisms on growing plants

Compositions having antimicrobial activity against a variety of microorganisms, including vegetative bacteria, bacterial spores, fungi, and fungal spores are particularly useful for microbiocidal treatments of a variety of substances. More specifically, compositions have antibmicrobial activity against microorganisms of the group such as , and are particularly useful. Compositions including hydrogen peroxide, a carboxylic acid, and a peroxycarboxylic acid in which the weight ratio of the peroxycarboxylic acid to the hydrogen peroxide is at least 4:1 are effective against microorganisms, particularly bacterial spores. Such compositions include a reduced amount of hydrogen peroxide relative to the amount of peroxycarboxylic acid as compared to conventional compositions. Compositions can also include a quaternary ammonium compound, a stabilizing agent, a surfactant, a hydrotrope, or other additives. Methods of using a composition including hydrogen peroxide, a carboxylic acid, and a peroxycarboxylic acid in which the ratio of the peroxycarboxylic acid to the hydrogen peroxide is at least 4:1 are useful for reducing the microbial numbers on a variety of substances contaminated by microorganisms, particularly of the group. Such substances include foodstuffs, water, general-premise surfaces, specific-equipment surfaces, animal carcasses, soil, and textiles.
