Beta-Ionone

When carotenoids breakdown they produce a range of degradation products but none is perhaps more important than beta-ionone. It is the principal breakdown product and is noted in the perfume industry especially because it has a  characteristic woody, violet, fruity, and raspberry‐like odor. The threshold value for this compound is only 0.007 ppb in water which is extremely low (Cremer & Eichner, 2000).

Sources

Lutein is one particular source but it occurs in all the carotenoid-rich fruits, plants and flowers. the principal sources are red pepper, tomatoes, carrots and even tea (Cremer & Eichner, 2000; Ziino et al., 2009).

Off-Flavours

It can be a major contributor to off-notes and off-flavours in various food products. dehydrated carrot, paprika, kimchi and some other fermented foods can be affected by too much of this compound. Fermentation of red pepper also leads to an overproduction of beta-ionone (Lee et al., 2018).
