产品概览 | Product Overview
茶黄素 是红茶在发酵（氧化） 过程中形成的一类具有苯并卓酚酮结构的金黄色色素，是决定红茶汤色“金圈”、滋味“鲜爽度”和“强度” 的关键品质成分。它们并非茶叶本身固有，而是由儿茶素（特别是表没食子儿茶素和表没食子儿茶素没食子酸酯）在多酚氧化酶催化下氧化聚合生成。茶黄素是红茶中最具生物活性的物质之一，其抗氧化能力远超维生素C和维生素E，被誉为茶叶中的“软黄金”。现代科学研究证实，茶黄素具有卓越的抗氧化、抗炎、降血脂、保护心血管、抗肿瘤、抗菌、抗病毒 等多重生理功能，尤其在调节血脂、预防动脉粥样硬化、保护肝脏和神经 方面表现出巨大潜力，是开发功能性食品、保健食品和天然药物的明星原料。
Theaflavinis a class of golden-yellow pigmentswith a benzotropolone structure formed during thefermentation (oxidation)process of black tea. They are key quality components determining the "brightness" of the liquor color and the "fresh briskness" and "strength" of the tastein black tea. They are not inherently present in fresh tea leaves but are generated through the enzymatic oxidation and polymerization ofcatechins(specifically epicatechin and epigallocatechin gallate) catalyzed by polyphenol oxidase. Theaflavins are among the most biologically active substances in black tea, with antioxidant capacity far exceeding that of Vitamin C and Vitamin E, hailed as the "soft gold" in tea. Modern scientific research confirms that theaflavins possess multiple physiological functions, including exceptional antioxidant, anti-inflammatory, lipid-lowering, cardiovascular protective, antitumor, antibacterial, and antiviraleffects. They show significant potential, particularly inregulating blood lipids, preventing atherosclerosis, and protecting the liver and nerves, making them a star ingredient for developing functional foods, health supplements, and natural medicines.

定向酶促氧化与精准控制技术：
茶黄素的传统制备依赖红茶自然发酵，含量低、成分复杂、批次差异大。我们采用体外多酚氧化酶模拟发酵系统，以高纯度儿茶素（EGCG/ECG等）为底物，在精密控制的温度、pH、氧气、时间 条件下进行定向酶促氧化。该技术可将茶黄素总产率大幅提升至15%以上，并能通过调控工艺参数，选择性富集特定类型的茶黄素单体（如TF、TF-3-G、TF-3,3'-DG），以满足不同功效研究和产品开发的需求，实现从“靠天吃饭”到“精准制造”的跨越。
*Traditional theaflavin preparation relies on natural black tea fermentation, resulting in low content, complex composition, and significant batch-to-batch variation. We employ anin vitro polyphenol oxidase模拟 fermentation system, using high-purity catechins (EGCG/ECG, etc.) as substrates, and conduct directional enzymatic oxidationunderprecisely controlled temperature, pH, oxygen, and timeconditions. This technology can *significantly increase the total yield of theaflavins to over 15%, and by adjusting process parameters, allows for the selective enrichment of specific theaflavin monomers(e.g., TF, TF-3-G, TF-3,3'-DG) to meet the needs of different efficacy studies and product development, achieving a leap from "reliance on natural conditions" to "precision manufacturing".
高效分离纯化与稳定性保护技术：
从复杂的氧化产物（含茶黄素、茶红素、未反应儿茶素等）中高效分离高纯度茶黄素是行业难题。我们集成运用高速逆流色谱、制备型高效液相色谱、大孔吸附树脂层析 等现代分离技术，实现了茶黄素单体纯度≥98%、总茶黄素提取物含量≥80% 的稳定生产。同时，针对茶黄素对光、热、pH敏感，易氧化聚合 的特性，我们开发了低温干燥、微囊包埋、添加稳定剂、无氧/避光包装 等一系列稳定性保护方案，确保产品在储存和应用过程中的活性与色泽稳定。
*Efficiently separating high-purity theaflavins from complex oxidation products (containing theaflavins, thearubigins, unreacted catechins, etc.) is an industry challenge. We integrate modern separation technologies such as high-speed counter-current chromatography, preparative HPLC, and macroporous adsorption resin chromatography, achieving stable production oftheaflavin monomer purity ≥ 98% and total theaflavin extract content ≥ 80%. Furthermore, addressing the sensitivity of theaflavins to *light, heat, pH, and their susceptibility to oxidative polymerization, we have developed a series of stability protection solutions including low-temperature drying, microencapsulation, addition of stabilizers, anaerobic/light-proof packaging, ensuring the activity and color stability of the product during storage and application.
