Nootkatone (see also noot.evolva.com) is a citrus ingredient that is characteristically associated with grapefruit. It is widely used in flavours and fragrances.
As a flavour and fragrance ingredient. Nootkatone is a highly “substantive” citrus flavour/fragrance ingredient, a rare characteristic that enables it to last on skin and cloth for an extended period of time. This means perfumers can use nootkatone to impart a fresh clean scent that holds up over time. As such nootkatone has broad potential as a flavour and fragrance ingredient in markets such as personal care and household cleaning.
Nootkatone is commercially produced by direct extraction from grapefruit oil or by oxidation of orange valencene (extracted from oranges). However, this process is very expensive and limits the use of Nootkatone to expensive fine fragrance compounds.
With Evolva’s process the costs can be significantly lowered and its use expanded to high-volume applications such as a fragrance for personal care, hair care and laundry care products. Evolva’s nootkatone has been scaled to commercial production and has received excellent feedback from flavour and fragrance customers.
In August 2015, Evolva launched nootkatone into flavour and fragrance applications.
