Composition Profile
Verified · 2026-09-26- 01Volatile aroma profile of Huoshan HuangdachaSDE detected 74 volatile compounds and HS-SPME detected 76, with 44 shared between the two methods. Furfural, 5-methylfurfural, 3-ethyl-2,5-dimethylpyrazine and methyl salicylate each exceeded 2% relative abundance in both methods.Dry-leaf sample
Furans, pyrazines and related compounds jointly contribute to the distinctive roasted and toasted-rice-like aroma.
- 02Flavor chemistry under different roasting intensitiesLarge-leaf yellow tea made from material collected in the Huoshan area was compared under light, medium and old-fire roasting. Old fire was critical to the characteristic toasted-rice-like aroma; trans-β-ionone contributed floral aroma and 2,3-diethyl-5-methylpyrazine contributed roasted aroma.Dry-leaf sample
- 03Flavoromics of whole tea, stems and leavesIn traditionally processed large-leaf yellow tea from Huoshan County, stems showed stronger roasted/nutty aroma and sweetness, mainly associated with higher theanine and soluble monosaccharides; leaves were richer in catechins and caffeine and contributed more to body and astringency.Dry-leaf sample
Its characteristic roasted-rice-like aroma arises from the combined action of furans, pyrazines, aldehydes, ketones and other volatiles. Roast intensity and the proportion of stems to leaves both significantly reshape aroma and taste chemistry.
