Black tea contains tannic acid, which contributes to its slightly astringent taste. Tannic acid is a type of polyphenol that is commonly found in various plant-based foods and beverages.
Pectic acid, pictine acid and tannic acid can be found in tea.
To detect the presence of tannic acid in tea, you can perform a simple experiment by adding a few drops of ferric chloride solution to the tea. If tannic acid is present, a blue-black color will form due to the formation of a complex between the tannic acid and ferric chloride. This color change indicates the presence of tannic acid in the tea.
The acid present in tea is called tannic acid.
Tea is an acidic solution.
No.Tea contains polyphenols (aka catechins), which are a specific type of tannin. Green Tea contains more of these substances (30-42% of the extractable solids) than Black Tea or Oolong Tea. Oolong Tea has 8-20% catechin content, and Black Tea is about halfway between Green Tea and Oolong Tea in catechin content. Tea does not contain Tannic Acid.
