What type of odors are persistent and result from burned meat or poultry?

The correct answer is based on the nature of the odors resulting from the combustion of animal protein. When meat or poultry is cooked at high temperatures, it undergoes a chemical change that produces distinct odors due to the breakdown of proteins and fats. These odors can be particularly potent and long-lasting, often referred to as protein odors.

Protein odors are often described as smoky or acrid, and they arise from the Maillard reaction and the pyrolysis of proteins. This makes them quite persistent in an environment, attaching to surfaces and being difficult to remove. Understanding this process is crucial for odor control professionals who need to identify the source of odors and apply the appropriate remediation methods.

In contrast, fungal odors come from mold and mildew, animal odors are associated with living or deceased animals, and chemical odors arise from synthetic substances or reactions unrelated to animal protein. Recognizing the specific source of these odors is key for effective treatment, which emphasizes the importance of understanding the fundamental differences in odor types.
