Sanitizing Methods § Heat. Iodine is also easier on skin than chlorine, though not as gentle as quaternary ammonium. There are three methods of using heat to sanitize surfaces. Pros: Relatively inexpensive, kills most microorganism, does not form film, easy to measure with test strips; There are different types of sanitizers that you could use, but the most common types are chlorine, quaternary ammonium solution and iodine. According to these results, chlorine and iodine disinfectants were quite effective against most of the viruses used … A second method is hot water, which is the most common method used in food establishments. The FDA Food Code identifies a few chemical sanitizers that are approved for use on food-contact surfaces, including chlorine, iodine, and quaternary ammonium. These vary depending on the type of solution used. Sanitizing method that are uses chlorine, iodine, and quaternary ammonium.A) heatC.) Use of chlorine bleach for sanitizing equipment and food handling articles: Dilute mixtures of chlorine bleach and water are a common and cost-effective method for sanitizing equipment in food processing operations. The first is exposing the surface to steam using one of the following time temperature schedules -- 170 degrees F for 15 minutes or 200 degrees F for 5 minutes. The most common sanitizing chemicals used in the food service industry are Chlorine, Iodine and Quaternary Ammonium Compounds. Besides chlorine, another well-known category of disinfectants is known as quaternary ammonium compounds. Typically chlorine sanitization requires exposure for 7 seconds at a temperature of 100 degrees Fahrenheit. When used properly, chlorine bleach can be a very ef-fective method of killing undesirable microorganisms. In the food industry, the most popular way to sanitize is with chemical sanitizers. There are some variations depending on pH factors. Quaternary ammonium compound induced detachment of the envelope of the enveloped viruses and formation of micelle in non-enveloped viruses. Processors cookingB.) Three primary chemical compounds are used as sanitizers in the food service industry: chlorine-based cleaners, quaternary ammonium and iodine sanitizers.Chlorine is the most commonly used chemical sanitizer agent, since it is highly effective and relatively inexpensive. To accurately test the strength of a sanitizing solution, determine which chemical is being used -- chlorine, iodine, or quaternary ammonium. cheinicalsD.) Sanitizer Testing Every restaurant must have the appropriate testing kit to measure chemical sanitizer concentrations. Each sanitizer has pros and cons, so here is the list of the most important ones: Chlorine. Three primary chemical compounds are used as sanitizers in the food service industry: chlorine-based cleaners, quaternary ammonium and iodine sanitizers.Chlorine is the most commonly used chemical sanitizer agent, since it is highly effective and relatively inexpensive. While it is not as long-lasting as quaternary ammonium, it lasts longer than chlorine in the presence of organic compounds. detergent4 One aspect in the lesson that I found it difficult tounderstand is the most important part of the salads Quaternary Ammonium Compounds.
