单宁, 鞣质
a natural compound in plants, like grapes and tea, that gives astringency to foods and drinks
Tannin is a naturally occurring compound found in various plants, particularly in the bark, leaves, and fruit skins. It is most commonly associated with tea, wine, and certain fruits like grapes, apples, and berries. Tannins have a bitter and drying taste, which can make the mouth feel dry. They play a role in protecting plants from pests and harmful microorganisms. In addition to their natural protective functions, tannins are used in the leather tanning industry to process animal hides and in the production of some inks and dyes. In the diet, moderate consumption of tannin-rich foods and drinks can offer antioxidant benefits, though excessive intake can interfere with nutrient absorption.
