金银花Lonicerae Japonicae Flos作为大宗常用中药材之一，具有清热解毒、疏散风热的功效，亦具有药食两用的特性。金银花因其较高的药用、食用和经济价值而被广泛用于临床、食品健康及化妆品等方面，使得金银花市场需求旺盛。然而金银花在加工、贮藏过程中易发生褐变，褐变不仅使金银花外观呈现黄褐色，影响消费者感官，还使其有效成分含量下降，影响其活性。因此，研究金银花的色变机制及控制技术，对保持金银花原有色泽和活性成分、选择合适的加工方式、延长贮藏时间及提高消费者满意度等具有重要意义。通过对金银花生长发育、加工及贮藏过程中颜色变化的物质变化规律、控制技术进行综述，为金银花色泽变化机制及控制技术的深入研究和应用发展提供参考。

Jinyinhua (Lonicerae Japonicae Flos), as a commonly used traditional Chinese medicine, has significant pharmacological properties including heat-clearing, detoxification, and wind-heat dispersion effects. It also has the characteristic of being both medicinal and edible. Its substantial medicinal potential, nutritional value, and commercial viability have facilitated extensive utilization across clinical therapeutics, functional food production, and cosmetic formulations. This has led to a strong demand for Lonicerae Japonicae Flos in the market. However, Lonicerae Japonicae Flos is prone to browning during postharvest processing and storage, which not only results in undesirable yellow-brown discoloration, diminishing consumer appeal, but also reduces bioactive compounds, thereby compromising therapeutic efficacy. Therefore, investigating the color change mechanism and control technology of Lonicerae Japonicae Flos is of great significance for maintaining its original color and bioactive compounds, selecting appropriate processing methods, extending storage time, and improving consumer satisfaction. Secondary metabolites change, the mechanism of color change and control technology during the growth and development, processing and storage on Lonicerae Japonicae Flos were reviewed in this paper, aiming to providing insights for the research and application of color change mechanisms and control technology of Lonicerae Japonicae Flos.
