oxidation of alcohols — aldehyde Alcohols may be oxidized to give aldehydes, ketones, and carboxylic acids. The oxidation of organic compounds generally increases the number of bonds from carbon to oxygen, and it may decrease the number of bonds to hydrogen.

Many aldehydes are naturally occurring organic compounds that play a significant role in the sensory profiles of fruits and vegetables. These compounds are frequently responsible for the distinct flavors and pleasant, fruity aromas associated with various plant-based foods.123

The contribution of aldehydes to these aromas is often specific to the type of plant. For example, benzaldehyde is a key aromatic aldehyde that imparts much of the characteristic scent and flavor to cherries and almonds. Other naturally occurring aldehydes serve as essential flavoring agents, such as cinnamaldehyde, which provides the aroma of cinnamon, and vanillin, the primary flavoring component found in vanilla beans.234
