What are the importance of tannins?

Tannins are polyphenolic compounds found in various plants, particularly in tea, wine, and certain fruits. They play a crucial role in plant defense by deterring herbivores and pathogens due to their astringent taste. In human consumption, tannins contribute to the flavor and mouthfeel of beverages like wine and tea, while also offering potential health benefits, such as antioxidant properties and anti-inflammatory effects. Additionally, tannins can aid in the preservation of food products by inhibiting microbial growth.
