Aroma compounds are chemical substances that contribute to the scent of various materials, including food, flowers, and essential oils. These compounds can be naturally occurring or synthetically produced and play a crucial role in flavor perception and fragrance. Common examples include vanillin in vanilla and linalool in lavender. These compounds interact with our olfactory receptors, allowing us to detect and identify different smells. Aroma compounds are essential in industries such as food and beverage, cosmetics, and perfume, where they enhance sensory experiences and influence consumer preferences.
