Tannins are found in which items according to the material?

• A. All of the above
• B. Cocoa
• C. Coffee
• D. Tea

Answer: (A)

Tannins are plant polyphenols that give an astringent, bitter sensation and occur in many plant-derived foods and beverages. Tea is well known for its tannins, including catechin-derived polymers and their oxidation products, which contribute to its astringency. Cocoa also contains tannins, adding to its bitter, astringent mouthfeel and influencing color. Coffee contains tannin-like polyphenols as part of its complex phenolic profile, contributing to bitterness and astringency as well. Because all three originate from plants and retain significant tannin content through processing, tannins are found in all of them. That’s why the material indicates tannins are present in every listed item.
