Abstract:

To understand the suitability of processing yellow tea, develop different shapes of yellow tea products, and enhance industrial vitality, the fresh leaves of Zhonghuang 1 tea tree variety were processed into five different shapes of yellow tea products. Through sensory evaluation and physical and chemical composition analysis, the results showed that Zhonghuang 1 has good suitability for processing yellow tea. The quality of processed curled- and flower-shaped yellow tea is better, with a tender yellow color, fresh and moist aroma, sweet and mellow taste, and a infusion aroma. Different shaping techniques have a significant impact on the quality of yellow tea, with a greater effect on the dissolution of physical and chemical components than on its absolute content. Excessive shaping time will significantly increase the concentration of ester catechins, thereby increasing bitterness and reducing taste quality.

Key words: shaping technique, yellow tea, quality
