Product Introduction
Main Functions
Among other functions, Yihe Biomedical Green Tea Extract is a key ingredient in the manufacture of teas, food items, and health supplements. Various lines of products that contain polyphenols such as TP98% EGCG50%, TP95% EGCG45%, TP90%, and TP50% EGCG15% are all available with caffeine levels below 1%. Besides that, there is also a line of products like EGCG 95-98% pure white grade, EGCG80-90%, EGCG70%, EGCG60%, Natural Theanine 20%-98%, Theaflavin TF40%-TF80% as well as instant tea powders, other tea extracts, and feed additive tea polyphenols 30%-98%.
Green Tea Extract helps in various ways e.g. facilitate lipid metabolism, combating oxidative stress, support bactericidal and detoxification functions, help alcohol detoxification and liver protection, supply detoxification assistance, and enhance the immune system according to the product details of Yihe Biomedical Green Tea Extract.
Moreover, it is not a single specification product but a product in a series, so the customers can pick the appropriate level depending on their active content, color demand, caffeine control, dosage form, and cost target.
Application Areas
Green Tea Extract is primarily used as raw materials for food and health products. They can be incorporated in capsules, tablets, solid drinks, instant beverage powders, functional tea formulas, nutrition blends, and other plant-based product systems. Those customers who look for highly active-content products will find the EGCG and polyphenol specifications for high concentrations most suitable. Conversely, for beverage or tea-style products, one may choose from instant black tea powder, instant green tea powder, instant Pu-erh tea powder, and instant oolong tea powder depending on product positioning.
Apart from the conventional food and health product formulations, customers may also be interested in feed additive tea polyphenol series that have a purity range of 30%-98%.
