AdministratorWhat is beta Damascenone used for?
beta-Damascenone is a major contributor to the aroma of roses, despite its very low concentration, and is an important fragrance chemical used in perfumery. The damascenones are derived from the degradation of carotenoids. In 2008, (E)-β-damascenone was identified as a primary odorant in Kentucky bourbon.
Where is Damascenone found?
grapes
Damascenone, a C-13 norisoprenoid, is an important aroma compound and is universally found in grapes and nearly all wines. It was first characterized as a rose ketone compound1 and has since been described as contributing aromas of honey, fruit, floral, tea, stewed apple, dry plum, dark berries and caramel2-4.
What does Damascone smell like?
Damascone is the mixture of cis-isomer and trans isomers that appears liquid with fruity and blackcurrant-like odor.
What are rose ketones?
The damascones belong to a family of chemicals known as rose ketones, which also includes damascenones and ionones. beta-Damascone is a contributor to the aroma of roses, despite its relatively low concentration, and is an important fragrance chemical used in perfumery.
What is beta ionone ring?
β-Ionone. β-ionone is a sesquiterpene with a structure analogous to the cyclical structure of β-carotene. This BFC occurring in grapes has antineoplastic properties, according to several studies (de Moura Espíndola et al., 2005; Cardozo et al., 2011; Scolastici et al., 2014).
What does ionone smell like?
violets
The combination of α-ionone and β-ionone is characteristic of the scent of violets and used with other components in perfumery and flavouring to recreate their scent.
Which ionone is related to vitamin A?
Vitamin A (Retinoids) Carotenoids with at least one β-ionone ring, especially β-carotene, provide the major retinoid precursors in most diets.
Where is beta ionone found?
β-Ionone as an aroma compound found in some representative fruits and vegetables. β-Ionone is an essential contributor to fragrance in the flowers of Boronia megastigma [49], in petunia (Petunia hybrida) [50], and in the yellow and red Lawsonia inermis L. (henna) flowers [51] (Figure 4).
What is ionone made of?
Ionone is a ketone compound composed of 13 carbons with a monocyclic terpenoid backbone. Several isomeric ionones exist in Nature, including α-ionone, β-ionone and others. Ionones are found as secondary plant metabolism products that share mevalonic acid as a common precursor.
Is ionone a ketone?
Ionone is a ketone compound composed of 13 carbons with a monocyclic terpenoid backbone [1]. The term ionone derived from “iona” (Greek for violet) referring to the violet scent and “ketone” in relation to its structure [2]. Several isomeric ionones exist in Nature, including α-ionone, β-ionone and others.
