Tea fermentation degree determination method

The invention relates to the field of tea leaf detection, in particular to a tea leaf fermentation degree determination method which comprises the following steps: acquiring a microscopic image of fully soaked and dried tea leaves; obtaining tea soup components of the fully soaked tea leaves; analyzing the fiber structure retention degree of the tea according to the tea microscopic image; and estimating the tea fermentation degree according to the fiber structure retention degree and the tea soup component composition. According to the method, estimation can be carried out according to comprehensive consideration of the fiber structure retention degree of the tea leaves and parameters related to the fermentation degree in tea soup components according to experience, so that fermentation degree data with data support can be obtained. 本发明涉及茶叶检测领域，具体涉及一种茶叶发酵度测定方法，包括如下步骤：获取已充分浸泡和干燥后的茶叶显微图像；获取茶叶已充分浸泡的茶汤成分组成；根据所述茶叶显微图像分析出茶叶的纤维结构保留度；根据纤维结构保留度和茶汤成分组成估算茶叶发酵度。本发明能够根据茶叶的纤维结构保留度以及茶汤成分中与发酵程度相关的参数根据经验进行综合考虑进行估算，这样能够得到有数据支撑
