Definition: Isone is a type of organic compound that is commonly used as a flavoring agent in food and beverages. It is made up of two carbon atoms bonded to three oxygen atoms, with one oxygen atom being adjacent to the carbon atoms. Isone has a high boiling point and a low melting point, making it an excellent candidate for use in food and beverage applications due to its ability to be used as a flavoring agent without the need for preservatives or other additives.
