ABSTRACT

The volatile compounds found in mangoes (Mangifera indica L.) obtained from three cultivars (TN, Tainong no. 1; KT, Keitt; and ZL, Zill; grown in China) were comprehensively analyzed by gas chromatography-olfactometry (GC-O), gas chromatography-mass spectrometry (GC-MS), and GC-flame photometric detection (GC-FPD) analyses. The results showed that 42, 35, and 45 compounds were identified in the TN, KT, and ZL samples, respectively. From these compounds, 19, 14, and 20 compounds were identified as important odorants with odor activity values (OAVs) greater than 1. Of these, 5, 7, and 5 sulfur compounds were respectively identified in the three samples by FPD. Importantly, methanethiol, ethanethiol, 1-propanethiol, methyl propyl disulfide, and 3-mercapto-1-hexanol were detected for the first time in mango. Five sulfur compounds were selected to study interactions using Feller's additive model, OAV, and Vector model. Among these mixtures, six mixtures exhibited a masking effect, three mixtures presented an additive effect, and one mixture showed a synergistic effect.
