Abstract

The article presents the results of studying the corrosiveness of seven complex disinfectants containing, along with peracetic acid (PAA), hydrogen peroxide and acetic acid. All samples were encrypted.
As test objects, details of the chicken processing line at the meat processing plant were used: bushings, fingers of a picking machine, round rubber discs, steel chain links, part of the conveyor belt and other parts of various shapes.
It was found that all tested disinfectants based on PAA have a corrosive effect on the test objects of the chicken processing line. The most aggressive in effect were the means with the codes 02/22 and 03/22. The use of such disinfectants is economically unprofitable for meat processing enterprises.
