Chen, Xiao published the artcileFree and glycosidic volatiles in tamarillo (Solanum betaceum Cav. syn. Cyphomandra betacea Sendt.) juices prepared from three cultivars grown in New Zealand, HPLC of Formula: 5405-41-4, the main research area is glycosidic volatile tamarillo juice cultivar; PCA; PLS-DA; glycosides; ripening; tamarillo; volatile.
This study investigated the free and glycosidic-bound volatiles in the juice samples of three tamarillo cultivars (i.e. Amber, Mulligan, and Laird’s Large) that are widely grown in New Zealand. Juice samples were prepared from fruits at different ripening stages (green, middle, and ripe). Headspace solid-phase microextraction combined with gas chromatog.-mass spectrometry was applied to analyze the free volatiles in the samples. A total of 20 free volatiles were detected. Among the samples, the ripe Mulligan juice gave the highest contents of free terpenoids (424μg/L) and esters (691μg/L). The glycosidic-bound volatiles were prepared by solid-phase extraction The matrix effect was evaluated based on the recovery rate of analytes containing multiple aglycon classes. From the results, Ph β-D-glucopyranoside was selected to compensate the matrix effect caused by insufficient acquisition of glycosidic volatiles during analyte preparation In all the ripe-fruit juice samples, the aglycons 4-hydroxy-2,5-dimethyl-3(2H)-furanone and trans-2, cis-6-nonadienal were found to give high odor activity values. According to multivariate statistical anal., 11 free volatiles and 22 glycosidic volatiles could be potentially applied as volatile makers to distinguish the juice samples. This study has provided a comprehensive understanding of the flavor chem. of tamarillo juices, with a focus on the potential role of glycosidic aglycons as aroma contributors to tamarillo products.
