-The main components of the volatiles of A. unedo fruits are alcohols, followed by aldehydes and esters. The main volatile compounds identified were (Z)-3-hexen-1-ol, 1-hexanol, hexanal, (E)-2-hexenal, and (Z)-3-hexenyl acetate, all with green odors. These are decreased in fully ripening state and mixed up with floral (linalool, alpha-terpineol) and sweet-waxy (methyl decanoate, mehtyl dodecanoate, ethyl dodecanoate) sensations. \\+The main components of the volatiles of A. unedo fruits are alcohols, followed by aldehydes and esters.

 "... fruits of A. unedo are rarely eaten as fresh fruit as despite their pleasing appearance, the taste is not much appreciated by the consumer. So far, they are generally used for obtaining alcoholic drinks (wines, liqueurs and brandies), jams, jellies and marmalades. They can also be incorporated into yoghurts either in pieces or as flavours and be used, like other berries in confectionery such as pie and pastry fillings, cereal products, among other applications... \\ "... fruits of A. unedo are rarely eaten as fresh fruit as despite their pleasing appearance, the taste is not much appreciated by the consumer.

-Strawberry tree honey is a known product of Mediterranean regions which is characterized for its “bitter taste”. Homogentisic acid (2,5-dihydroxyphenylacetic) has been considered as a chemical marker of the botanical origin of strawberry tree honey along with (±)-2-cis,4-trans-abscisic acid (c,t-ABA), (±)-2-trans, 4-trans-abscisic acid (t,t-ABA) and unedone. From the aromatic profile of strawberry tree honey from Sardinia (Italy) and Canary islands (Spain) some authors reported that norisoprenoids such as α-isophorone, β-isophorone and 4-oxoisophorone (Figure 8) could be considered specific floral origin markers.
