Detection Principle	Tannins are a class of natural polyphenolic compounds that are widely present in plants and have the property of binding with proteins, alkaloids and polysaccharides. With biological activities such as antioxidant, anti-inflammatory, and antibacterial effects, tannins have extensive applications in nutritional research, agricultural and plant sciences, and industrial fields. This kit determines the tannin content in the sample by measuring the OD value at 760 nm of the blue compound produced by the reaction between the sample and the chromogenic reagent under alkaline conditions.

The recommended dilution factor for different samples is as follows (for reference only):

Sample Type	Dilution Factor
Peach juice	2-6
Orange juice	3-8
Red wine	5-10
10% Blueberry tissue homogenate	2-5
10% Orange tissue homogenate	1
