Hi,

Tannin extraction methods are mentioned on page 55 of this PDF file:

http://www.users.muohio.edu/hagermae/tannin.pdf

Here is a paper investigating the efficacy of different methods of extraction:

Here is the documentation for an ASTM standard method for extracting tannins. Check with a local college or technical library to obtain free access to the method:

http://www.astm.org/Standards/D6405.htm

Here is another study on the extraction of tannins for indeustrial purposes:

To find more information on this try a google search on tannin extraction.

Best regards,
