摘要/Abstract

摘要： 茶叶品质等级是决定茶叶销售价格的重要参考指标,但市场上茶叶等级虚标现象时有发生,严重损害消费者权益。目前,茶叶等级主要是通过感官审评进行评定。感官审评经过长期的发展已形成了较为统一的标准,但存在一定的主观性。为了更准确、客观地评价茶叶等级,研究人员发展了系列茶叶等级量化评价方法。鉴于茶叶等级评价的重要现实意义,综述了近年来应用广泛的仿生传感智能感官检测技术、特定化学成分检测技术和代谢组学技术在茶叶等级量化评价中的研究现状,分析其在茶叶等级评价中面临的关键问题和挑战,并进行了展望,对茶叶品质的客观、科学、规范化评价与质量控制具有积极的指导意义。

Abstract: Grade is an important indicator for discerning the quality of green tea and other types of tea, and it is directly related to their selling prices. However, there is often a phenomenon of falsely labeling tea grades in the market, which seriously undermines consumer rights. At present, tea grade is mainly assessed by sensory evaluation. Sensory evaluation, after long-term development, has formed relatively unified standard, but it still has a certain subjectivity. To evaluate the tea grade more accurately and objectively, researchers have developed a series of quantitative evaluation methods for tea grade. Given the significant practical importance of evaluating tea grade, this article provided a comprehensive review of the recent research status in the qualitative and quantitative evaluation of tea grades, including bionic sensing intelligent sensory detection technology, specific chemical components detection and metabolomics techniques. Major problems and challenges on tea grade evaluation were discussed, and future development trend was also prospected in this study. It has positive guiding significance for objective, scientific and standardized evaluation and quality control of tea quality.
