Manilkara zapota (L.) P.Royen - syn. Achras zapota L. - Sapotaceae - sapodilla, naseberry, Breiapfelbaum, Kaugummibaum, Sapote, Sapotillbaum

Evergreen tree, 12-20m high, native to Central America and the Caribbean, cultivated for its fruits elsewhere.

The bark is rich in a white, gummy latex called chicle, used for the production of chewing gum. The sapodilla fruits owning a exceptionally sweet and malty flavor. wikipedia

Liquid-liquid distillation of the fresh fruit pulp (fruits cultivated in Venezuela) with water/2-methylbutane yielded an essence (only 5µg/kg) with a strong aroma, characteristic for the fruit. „A group of 'benzyl-related' compounds comprised 45% of the essence and included a series of five alkyl benzoates. Methyl benzoate and methyl salicylate were both described as having sapodilla fruit aroma on odor evaluation of seperated components at an odor port at the exit of the GC column. Ethyl benzoate and propiophenone had related aroma characteristics.

Of the 23 volatile compounds characterized in the headspace of fresh sapodilla fruit, the major components were ethyl acetate (29%), acetaldehyde (21%), benzyl alcohol (11%), an unknown compound (8.9%, destroyed mainly on heating), 2-butenyl benzene (7%), methyl acetate (2%), 3-(1-ethoxyethoxy)-2-methyl butanal (2%) and benzenediol (1%).

Main volatile components of the fruit juice were methyl isoeugenol (12.9%), 1-methoxy-4-(4-methyl-4-pentenyl)benzene (10.9%), methyl salicylate (9.8%), vinyl benzoate (8.5%), benzylalcohol (7.6%), butyl butyrate (6.5%), dihydrocinnamyl acetate (4.7%), ethyl hexanoate (4.3%), dihydrocinnamal (3.9%), propyl acetate (3.7%), isoamyl acetate (2.5%), and ethyl hexadecanoate (2.5%).

„Calculation of the odour activity values (OAVs) of the aroma-active compounds showed that the overall aroma note of the fresh fruit was mainly caused by ethyl benzoate, E-2-hexenal, and β-caryophyllene. However, α-sinensal and to a lesser extent ethyl benzoate, E-2-hexenal, β-caryophyllene, and hexyl benzoate were responsible for the overall aroma of the dried fruit…
The aromaactive compounds exhibited an array of odour qualities such as pungent/fruity, nail-polish-like, sweet/fruity, green/grass-like, malty, almond-like, minty, woody/spicy and sweet/balsamic. Sniffing of serial-dilution of the fruit extracts revealed that the minty (ethyl benzoate), almond/floral-like (methyl benzoate), floral-like (pentyl benzoate), and malty (3-methyl-1-butanol) possessed the highest FD factors (32-64). High FD factors ≥ 8 and < 32 were determined for 3-methyl acetate, ethyl acetate, E-2-hexenal, hexan-1-ol, 2-methyl butanoate, benzaldehyde, benzyl alcohol, β-caryophyllene and hexyl benzoate. In addition, high FD factor was determined for α-sinensal in the dried fruit.“
