Non-Destructive Assessment of Aroma Volatiles from a Climacteric Near-Isogenic Line of Melon Obtained by Headspace Stir-Bar Sorptive Extraction.

ABSTRACT: A climacteric aromatic near-isogenic line (NIL) of melon (Cucumis melo L.) SC3-5-1 contained an introgression of the non-climacteric Korean cultivar "Shongwan Charmi" accession PI 161375 (SC) in the genetic background of the non-climacteric cultivar "Piel de Sapo" (PS). The aroma production was monitored during ripening at 21 °C in intact fruit using headspace sorptive bar extraction (HSSE). Bars were composed of polydimethylsiloxane (PDMS) and aromas were desorbed and analyzed by gas-chromatography mass-spectrometry. The aromatic profile was composed of 70 aromatic compounds plus 21 alkanes with a predominance of esters, particularly acetate (2-methylbutyl acetate, 2-methylpropyl acetate, hexyl acetate, and phenylmethyl acetate). Some compounds were severely affected by postharvest
