Activity of washing-disinfecting means “San-active” for sanitary treatment of equipment of meat processing enterprises in laboratory and manufacturing conditions

Abstract

The article presents the results of the research of the new detergent agent “San-active” for meat processing enterprises. It was established that “San-active” in the concentration from 0.3 to 2.0% is moderately alkaline (concentration of hydrogen ions is 11.44–12.7), at a concentration of 2.5% and above, with very alkaline pH ≥ 13.11 units. In the “San-active” detergent, at the concentration from 0.3 to 2.5%, the surface tension is 34.97–28.24 mN/m. The absorbability of the parts of the technological equipment with the solutions of the “San-active” means sharply increases with increasing concentration. At the temperature of solutions of the medium 19.0 ± 1.0 °С the angle of wetting decreases from 69.8 degrees. at a concentration of 0.3% to 50.5 degrees. at a concentration of 2.5% (in 1.4 times). It has been established that “San-active” in 0.5% concentration provides the bactericidal effect on test cultures of conditionally pathogenic bacteria, spore-forming microorganisms and fungi. The “San-active” agent at 0.5% concentration is bactericidal to S. aureus and E. faecalis cells that are in a biofilm in 10 minutes of exposition. For the inactivation of E. coli and P. aeruginosa cells in a biofilm, it is necessary that the “San-active” acts in a concentration not lower than 0.5% and not less than 30 minutes. The agent shows a washing effect on the evaluation of “good” at 0.5% concentration, and 1.0% and above the concentration on the score “excellent”. “San-active” in the concentration from 1.0 to 2.0% shows very weak corrosion activity on stainless steel. The use of “San-active” detergent for the sanitary treatment of equipment surfaces in the intestinal workshop at the concentration of the working solution 1.0–2.0% and the temperature 60 ± 5 °C for 20 minutes provides 99.9–100% efficiency of sanitary treatment.
