Abstract
In this study, the dynamic changes of different anthocyanins in the processing of ‘Ziyan’ tea wine were investigated quantitatively. Results showed that six types of anthocyanins, namely petunidin, malvidin, pelargonidin, delphinidin, cyanidin and peonidin, as well as two co-pigmented substances, procyanidins and flavonoids, were detected in ‘Ziyan’ tea wine. As fermentation proceeded, the contents of petunidin, pelargonidin, delphinidin, cyanidin and peonidin decreased. Among them, petunidin, peonidin and pelargonidin showed a tendency of decreasing first, then increasing and finally decreasing, whereas delphinidin and cyanidin continued to decrease during fermentation. Variation trend of procyanidins and flavonoids was consistent with those of petunidin. Furthermore, metabolism of delphinidin, cyanidin and pelargonidin were main pathways responsible for the anthocyanin changes during ‘Ziyan’ tea wine processing. These findings suggested that the color of ‘Ziyan’ tea wine was achieved by the combination of various anthocyanins in different ratios and the co-pigmentation of procyanidins and flavonoids.
期刊介绍:
Food Chemistry: X, one of three Open Access companion journals to Food Chemistry, follows the same aims, scope, and peer-review process. It focuses on papers advancing food and biochemistry or analytical methods, prioritizing research novelty. Manuscript evaluation considers novelty, scientific rigor, field advancement, and reader interest. Excluded are studies on food molecular sciences or disease cure/prevention. Topics include food component chemistry, bioactives, processing effects, additives, contaminants, and analytical methods. The journal welcome Analytical Papers addressing food microbiology, sensory aspects, and more, emphasizing new methods with robust validation and applicability to diverse foods or regions.
