Abstract
Aim. Development of technology for the use of detergent and disinfectant «KATELON 404», assessment of its antimicrobial efficacy and development of methods for controlling active substances. Materials and Methods. Methods of controlling the concentration of active substances in the concentrate of the detergent and disinfectant «KATELON 404» ‒ determination of the content of nitric acid by the method of acid-base titration and polyhexamethylenebiguanidine hydrochloride by the spectrophotometric method with Eosin N. Results. An environmentally safe (phosphate-free) acid detergent and disinfectant based on nitric acid and polyhexamethylenebiguanidine hydrochloride – "KATELON 404" has been developed. Recommendations on the choice of the effective concentration, exposure time, temperature for both washing and disinfection against bacteria, viruses and fungi (fungicidal activity) are proposed. Express and simple methods of analytical control of active substances in the concentrate of the agent have been developed. The absence of phosphoric acid (phosphates) in the composition ensures food safety and made it possible to successfully test KATELON 404 at a number of dairy enterprises (Kopylsky Butter Cheese Plant, Lyubansky Cheese Making Plant, Verkhnedvinsky Butter and Cheese Plant). Conclusion. A phosphate-free agent based on nitric acid and polyhexamethylenebiguanidine hydrochloride has been developed for all branches of the food industry, which is intended for the simultaneous washing and disinfection of containers, pipelines, cheese molds from protein-fatty and carbohydrate contaminants from ceramic, plastic, glass surfaces, stainless steel surfaces. The introduction of a special acidic component into the "KATELON 404" product made it possible to effectively remove milk and water stones, fossilized mineral and phosphate-calcium deposits, beer stone, scale, and rust. "KATELON 404" can be produced without foam and used for disinfection and washing of closed-loop systems (CIP systems) in the dairy industry.
