摘要: 茶叶揉捻中,成条率随揉捻时间的增加而表现出二次曲线变化规律,其数学模型为: y=5.6277x–0.077x2–17.1439; 细胞破损率随揉捻时间的增加而表现出指数曲线的变化规律,y=85.3e–11.9/x;为了提高绿茶品质,揉捻时间宜控制在30~40βmin。

关键词: 茶学, 茶叶揉捻, 数学模型, 成条率, 细胞破损率。

Abstract: In tea rolling, the rolled twig rate is expressed as the regularity of twice curve equation with the extension of rolling time, the mathematical equation is: y=5.6277x–0.077x2–17.1439 and the broken cell rate is expressed as the regularity of the natural logarithm curve equation, the mathematical equation is: y=85.3e-11.9/x . For improving the quality of tea, the rolling time would be controlled between 30~40βminutes.

Key words: Tea science, Tea rolling, Mathematical model, Rolled twig rate, Broken cell rate
