Volatile Components and Preliminary Antibacterial Activity of Tamarillo (Solanum betaceum Cav.).

ABSTRACT: Tamarillo is a nutrient-dense fruit with a unique aroma from its volatile compounds (VCs). In this study, we aimed to compare the volatile profiles: (i) of fresh and freeze-dried tamarillo; (ii) detected using Thermal Desorption-Gas Chromatography-Mass Spectrometry (TD-GC-MS) and Solid-Phase MicroExtraction-Gas Chromatography-Mass Spectrometry (SPME-GC-MS); (iii) of freeze-dried pulp and peel of New Zealand grown tamarillo. The possible antibacterial activity of freeze-dried tamarillo extracts was also investigated. We show that freeze-drying maintained most of the VCs, with some being more concentrated with the loss of water. The most abundant VC in both fresh and freeze-dried tamarillo was hexanoic acid methyl ester for pulp (30% and 37%, respectively), and (E)-3-Hexen-1-ol for peel (36%
