Our nootkatone. A fresh alternative.

Sustainably produced nootkatone with a minimum purity of 98%. Perfect for flavors and fragrance applications.

The highest purity, quality and availability

Our unique fermentation technology and process results in nootkatone with a purity of at least 98%.

Stringent controls and testing ensures that our nootkatone is always manufactured and delivered to a consistently high quality.

Our product is always readily available. How do we achieve this?

By fermenting nootkatone we overcome common supply chain issues caused by the crop shortages that result from variable weather, disease and drought.

A Versatile Ingredient

Nootkatone is a natural ingredient that occurs in grapefruit and certain other plants and is responsible for the characteristic smell of grapefruit. Due to its versatility it drives consumer preference across a wide range of foods and beverages along with fragrance, personal care and home products.

By brewing our nootkatone from sugar, rather than extracting it from the skin of grapefruits, Evolva’s process allows nootkatone to be made in large amounts in a highly reproducible, contaminant free, sustainable and affordable manner.
