What is the main purpose of a disinfectant?

The primary purpose of a disinfectant is to kill bacteria and other pathogens on surfaces or in substances, making them safe and hygienic for use. Disinfectants contain chemical agents specifically designed to eliminate harmful microorganisms that can cause foodborne illnesses or other infections. This is critical in maintaining cleanliness in food preparation areas and ensuring that any equipment or surfaces that come into contact with food are sanitized properly.

When looking at the other choices, removing dirt pertains more to cleaning agents, which focus on dirt and stains rather than microbial threats. Greasing surfaces is relevant to cooking and food preparation but does not address sanitation or safety concerns. Flavored food appeals to taste and culinary enhancement rather than hygiene or sanitation purposes. Therefore, the emphasis on killing bacteria distinguishes disinfectants from other substances involved in food safety and preparation.
