                                Aldehydes are a class of organic compounds found naturally in plants and animals that contribute significantly to the aroma and flavor of many foods. From the pleasant scent of vanilla and cinnamon to the reactive compounds formed during high-heat cooking, aldehydes are a common part of our diet.
