β-Glucogallin is primarily recognized for its role in the biosynthesis of hydrolysable tannins, which are compounds with significant antioxidant properties. It serves as a key intermediate in the production of these tannins, which are widely utilized in the food and beverage industry for their ability to stabilize flavors and extend shelf life. In the pharmaceutical sector, β-Glucogallin is explored for its potential therapeutic effects, particularly in reducing oxidative stress and inflammation, which are critical factors in the management of chronic diseases. Additionally, its application in skincare products is gaining attention due to its antioxidative properties that help in protecting the skin from environmental damage and aging. Research is ongoing to further elucidate its benefits and potential uses in various health and industrial applications.
