It is found naturally in coconut oil and palm kernel oil, and is used in the food industry for flavoring and as a preservative. Its sensory characteristics include a waxy, fatty odor, and it contributes to the flavor profile of various dairy products. In health contexts, decanoic acid is noted for its potential benefits in ketogenic diets and may have antimicrobial properties. It is also studied for its role in energy metabolism.
