Consumer Advice
Tannins (food-grade tannic acid) are natural polyphenols extracted from plants such as gallnuts, acorns and grape seeds. In food they act mainly as clarifying agents for wine, flavour modifiers and colourings, and they also occur naturally in tea and wine. Tannins are approved in the EU (E181) and are used as processing aids in China. They are considered safe at approved levels, though very large intakes can reduce iron absorption.
