Which of the following is a type of chemical sanitizer used in professional kitchens?

Quaternary ammonium compounds, commonly known as quats, are a specific type of chemical sanitizer frequently used in professional kitchens. They are effective against a wide range of bacteria, viruses, and fungi, making them suitable for sanitizing surfaces and equipment in food service environments. Quats are favored for their low toxicity, stability, and ease of use, often requiring a simple dilution in water to create a sanitizing solution that is safe for food-contact surfaces.

In contrast, soap is primarily a cleaning agent rather than a sanitizer, as it is designed to remove dirt and grease rather than to kill pathogens. While vinegar has some antibacterial properties and can be used for cleaning, it is not classified as a sanitizer effective enough for food safety standards in professional settings. Bleach is a strong chemical that can work as a sanitizer; however, its use is more regulated due to potential harmful reactions if not used properly, especially concerning food surfaces. Thus, while both bleach and quats serve as sanitizers, quats are more commonly preferred in the culinary context for their safer and more versatile application.
