Astringent biomolecules that are extracted from plants and fruits are referred to as Tannin. It can be found in the bark, stem tissues, roots, seeds, and leaves of plants, among other plant parts. Additionally, plants contain a lot of tannin, which shields them from predators and aids in controlling their growth. Cranberries, blueberries, strawberries, hazelnuts, pecans, walnuts, grapes, and oranges are a few examples of fruits with high tannin content. In addition to fruits, tannins are also present in beer, red wine, coffee, and tea.
Additionally, medications make use of tannins. One example is witch hazel, a common ingredient in skincare and personal care products and a source of tannin.Tannin is a biomolecule that is taken out of plants and fruits. Plants' seeds, stem tissues, roots, leaves, and bark all contain it. Gymnosperm and angiosperm plants contain the greatest tannin. It aids in the production of plant hormones and defends the plants against predators. Oranges, grapes, walnuts, pecans, hazelnuts, strawberries, blue berries, and cranberries are just a few examples of fruits that are high in tannin.
