摘要: 剪切特性指标可以用来评价茶叶的嫩度,本文通过剪切试验获得了茶叶剪切特性的力学指标(硬度、破坏能、破坏力及破坏应力等),同时针对茶叶梗直径尺寸较小,运用图像分析的方法,获得茶叶梗外形尺寸及其他参数,综合分析建立了不同品种茶叶嫩度和剪切力学指标之间的数学模型,为客观评价茶叶的等级提供新的手段和研究方法。

关键词: 茶叶, 嫩度, 剪切特性, 品质评价

Abstract: Shearing properties can be used to evaluate the tenderness of tea. The mechanical properties on tea shear inderes (hardness, failure energy, failure force and failure stress and so on) were tested through the sheer test. At the same time the tea shoot dimension and other parameters were obtained by using the image analysis method on tea shoot with smaller diameter, Besides, a mathematical model between the different tea cultivars of shoot tenderness and the shear mechanics was established, so to provide the new means and methods for the objective evaluation of the tea grade.

Key words: tea, tenderness, shearing properties, quality evaluation
