👉 "Legumelin" is a chemical compound that is commonly found in plants, particularly in the bark of certain trees. It is also known as "tannin," and it plays an important role in the flavor and texture of many plant-based foods such as coffee, tea, cocoa, and chocolate. The chemical structure of legumelin is very similar to that of other tannins found in plants, including tannic acid, tannin hydrolysates, and lignin.
