Comparative analysis of flavonoid, carotenoid, and organic acid profiles in various commercial dried citrus chips

초록

This study analyzes the flavonoid, carotenoid, and organic acid profiles of 18 commercial dried citrus chips, including 6 Korean and 12 imported cultivars, which are categorized into citron, pomelo, and mandarin groups based on their origin. Hesperidin and narirutin predominate in citron and mandarin groups, whereas naringin is prevalent in pomelo group. Green tangerine chip showed the highest contents of hesperidin (3180.24 +/- 296.55 mg/100 g) and narirutin (424.98 +/- 9.23 mg/100 g), while grapefruit chip had the highest naringin content (1916.66 +/- 89.66 mg/100 g). beta-cryptoxanthin was detected in the citron and mandarin groups, with tangerine chip containing the highest amount (18.35 +/- 0.99 mu g/g). The citron group exhibited higher organic acid concentrations than pomelo and other mandarin groups. The highest and lowest ascorbic acid contents were found in grapefruit chip and kumquat chip, at 2973.56 +/- 56.78 and 111.84 +/- 2.17 mg/100 g, respectively.
