    BACKGROUND: Quality properties of 14 saffron samples from Iran, Spain, and Türkiye were compared. RESULTS: Significant differences were observed between anthocyanins, volatile compounds, fatty acids, total phenolic content, and antioxidant activity of saffron samples (P < 0.05). Besides, significant differences in color parameters were observed. Moreover, a total of 13 volatile compounds were identified in the saffron samples using. headspace–solid-phase microextraction–gas chromatography–mass spectrometry, safranal and ?-isophorone being the two predominant aroma compounds. Regarding fatty acids, significant differences were seen in the fatty acid profiles of saffron samples (P < 0.05), while linoleic acid was the most concentrated fatty acid. In terms of sensory properties, different concentrations of safranal, ?-isophorone and 4-ketoisophorone may lead to significant differences in the odor and taste attributes of saffron samples (P < 0.05). CONCLUSION: Changes in corm origin along with climate and agricultural conditions may affect the quality characteristics of saffron cultivated in different geographical areas to a significant degree. © 2024 The Authors.
