Effects of Various Drying Parameters on the Volatile and Non-Volatile Compositions of 'Qiancha 1' White Tea.

ABSTRACT: 'Qiancha 1' is an excellent raw material for manufacturing white tea. The effects of different drying parameters on the quality performance of 'Qiancha 1' white tea remain poorly understood, which restricts the precise regulation of the quality of 'Qiancha 1' white tea. In this research, we systematically investigated the influence of drying temperature (65 °C, 75 °C, and 90 °C) and drying duration (1 h, 2 h, and 3 h) on its non-volatile and volatile compositions, using sensory evaluation, E-tongue, and non-volatilomic and volatilomic analyses. The results showed that the tea sample dried at 65 °C for 3 h had a sweet, mellow, and fresh flavor and scored 95 points, but high-temperature drying (90 °C) could promote increased bitterness and decreased sweetness. High-temperature drying was clo
