The Importance of Nootkatone

Nootkatone is a natural aroma ingredient that occurs in grapefruit and certain other plants. It is responsible for the characteristic smell of grapefruit. However, until now its use has been limited by its high price, limited supply and product quality.



With demonstrated safety, it is approved in all major countries for use in F&F, and is formulated today in a vast assortment of foods, drinks and skin care products.


A Versatile Ingredient                                                                                         

High-purity, with a taste and aroma typical of grapefruit, Nootkatone is well suited for a broad range of products such as fragrances, food, beverages, personal care and home care products.
