Objective

To investigate the suitability of 3 kinds of tea plant varieties in Fuliang County for black tea production.

Methods

Fuliang black tea was produced using the Group variety, Zhuyeqi and Zhuye variety as raw materials. The sensory quality, biochemical components and flavor compounds of the 3 kinds of Fuliang black teas were systematically compared.

Results

Sensory evaluation indicated that Zhuyeqi exhibited prominent golden tips, a pure red-yellow liquor color and the highest overall score; Zhuye variety produced the brightest liquor color. Physicochemical analysis revealed significantly higher water-soluble substances (43.53%±0.02%), caffeine (43.70mg/g), catechin gallate(0.67%±0.01%) and gallic acid (4.11 mg/g) in Zhuye variety; higher tea polyphenols (8.85%±0.13%) and catechins(0.37%±0.02%) in Group variety; and superior theabrownins (7.23%±0.05%) accumulation in Zhuyeqi. Analysis of the taste activity value (TAV) showed that caffeine was a common key bitter compound, while epigallocatechin and gallic acid contribute to astringency to varying degrees across different varieties. Specifically, epigallocatechin (TAV=1.08)was the key bitter compound in Group variety; epicatechin (TAV=1.15) was the key astringent compound in Zhuyeqi;and catechin gallate (TAV=1.22) was the key astringent compound in Zhuye variety. The aroma components varied significantly. Geraniol was the dominant aromatic component in Group variety (33.09%) and Zhuyeqi (29.91%),imparting rose-like and sweet fragrance notes, whereas Zhuye variety exhibited a balanced profile consisting of β-linalool (25.38%) and geraniol (17.24%).

Conclusion

This study clarifies the differences in sensory quality,characteristic flavors and aroma components among the 3 kinds of varieties, providing experimental basis for variety selection, targeted processing and quality control of Fuliang black tea.
