Compared with hypochlorites, chlorine dioxide requires much lower concentrations to achieve microbial mortality. Chemical Disinfectants and Sanitizers Disinfectants. In routine use, surfaces must be as free as possible of organic materials, and the pH must be maintained between 5 to 7 to ensure that the greatest amount of hypochlorous acid is available. As sanitizers, QACs are commonly applied at 200 ppm to food contact surfaces, and the solution is allowed to dry. Chlorine dioxide is an oxidizer that reacts with the proteins and fatty acids within the cell membrane, resulting in loss of permeability control and disruption of protein synthesis. 1984. The cleaner utilized in the cleaning step needs to be oriented and appropriate for the soil present. 13. For example, a 5-ppm solution is effective as a sanitizer on food contact surfaces with a contact time of at least 1 minute. Current News about Florida Chemical and the industries we service. As you probably have noted, no mention has been made of another chemical used extensively, namely, water. While QACs tolerate light organic loads, heavy soil will decrease QAC activity significantly. Thankfully, modern cleaning agents are mixtures of chemical components that can address various cleaning scenarios. Powdered Vehicle Wash An all purpose powdered vehicle wash … In general, QACs are effective against a wide range of microbes, although the spore phase is unaffected. These solutions are applied at concentrations ranging from about 100 ppm to 200 ppm for peroxyacetic acid and 80 ppm to 600 ppm for hydrogen peroxide. Too little sanitizer, of course, can result in unacceptable efficacy, while too much sanitizer can yield residues that do not meet standards. Water Res 11:727–729. 1986. 10.

At lower concentrations, Gram-positive bacteria are more sensitive to QACs than Gram-negative bacteria.10 QACs are formulated in many different variations for specific situations. Food Surface Sanitizers and Disinfectants From Velocity Chemical. Solutions should not be sprayed when children are nearby to avoid inhalation and exposing skin and eyes. McDonnell, G.E. [8] Carriers with iodophor solutions allow a sustained-release effect, resulting in continuous microbial mortality. McBain, A.J., R.G. Hypochlorite use may be further restricted in the future. It then becomes imperative to know what organisms are specifically present so that the proper disinfectant at the proper strength maintained for the required time can be applied. 3. TOPMOST CHEMICAL & PAPER | 3394 Winchester Rd. Basic elements of equipment cleaning and sanitizing in food processing and handling operations. U. S. Environmental Protection Agency, Antimicrobial Pesticide Products Fact Sheet. The difference between disinfectants and antiseptics is important in medicine, as they are used on different types of surfaces. The generally accepted order of events is rinse, clean, rinse and sanitize. Of course, the task of ensuring the chemicals are prepared and applied properly to avoid inappropriate residues rests with the food processor and foodservice operator. Once applied, the allowable residues and the monitoring thereof in food processing and preparation are the responsibility of the U.S. Food and Drug Administration. He can be reached at apfuntner@msn.com. [9]

To achieve the required level of sanitization or disinfection, the chemical in question must be applied at a certain concentration for a specified amount of time. [2] While disinfection measures may be employed in food processing and preparation, it is much more common to utilize sanitization methods to reduce microbial presence. References
Other disadvantages of hypochlorites are corrosiveness to metals, health concerns related to skin irritation and mucous membrane damage and environmental contamination. [1] To sanitize means to reduce microorganisms of public health importance to levels considered safe, based on established parameters, without adversely affecting either the quality of the product or its safety.
