Flower-scented teas become increasingly popular to new generations, due to their infused floral essences of diverse volatile compounds and additional health functions. Flower-scented teas have significantly broadened the spectrum of aroma perception, intensity, and longevity. Here,Chimonanthus praecoxflowers were used to scent tea dhools to create different Chimonanthus teas with strong and characteristic aromas. The dynamic absorption of aromas by three tea dhools, and aroma compatibility in three flower-scented teas, and the aroma retention in Chimonanthus teas during storage were investigated. At least twelve aroma compounds were selectively absorbed by three tea dhools, with seven compounds, pulegone, 3-phenylpropanol, (E)-cinnamaldehyde, cinnamyl alcohol, γ-phenylpropyl acetate, (E)-isoeugenol, and (E)-cinnamyl acetate, commonly absorbed to three Chimonanthus teas. The different absorption preferences to floral volatiles and absorption capacity of three tea dhools could be related to their surface structures and trichome conditions. Linalool, phenylmethyl acetate, and methyl salicylate as significant volatile components were substantially enhanced for both Chimonanthus flowers and tea dhools, thereby augmenting the floral bouquet of Chimonanthus tea. After 56 days of storage, alcohol volatiles emerged as the predominant volatile types, although esters are the major contributors to the aroma of freshly prepared Chimonanthus teas.
Novel Chimonanthus teas with appealing flavors and enhanced health benefits were created by scenting various tea dhools with medicinal Chimonanthus praecox flowers. Primary volatile compounds, including linalool, methyl salicylate, indole, cinnamyl alcohol, and eugenol, were effectively absorbed into tea dhools. Averagely 12 volatile compounds were absorbed into the scented black and green tea. Approximately 9.4 % and 17.8 % of new aroma were transferred from white flowers to scented black and green tea, respectively. Phenylmethyl acetate emerged as the most significantly absorbed volatile in both scented black tea and green tea. Moreover, the green tea scented with yellow flowers contained more aroma (34.2 %) than these with white flowers. ( E )- β -ocimene was the most abundantly absorbed volatile in yellow flowers-scented green tea. Green tea dhools performed better in absorbing fragrances from Chimonanthus flowers than black tea. Storage effect on Chimonanthus tea aroma persistence were evaluated for Chimonanthus tea production.
