Tannins are thus able to stabilize emulsions under certain conditions.
In the conditions tested, their chemical structures had a
strong impact on their physicochemical properties: grape tannins
stabilizing properties increased with their DP, and for a given DP,
galloylated tannins (i.e. grape seeds tannins, having 25% (w/w)
of epicatechin gallate units) seemed to be more efficient than apple
tannins.
