Hydrolysable Tannin-Protein Interactions: The Devil Is in the Structural Details

Tannins and their various bioactivities have been studied for decades because of the multiple bioactivities they express. Due to the high number of studies carried out with various methods, varying tannin and protein sources as well as variable tannin purities, it is difficult to combine these results and fashion them into a meaningful whole. Moreover, regarding bioactivity, the devil is in the details and small changes in tannin structure may drastically alter the obtained bioactivity.
