In vitro adsorption-desorption of aflatoxin B1 on Pepper's lignins isolated from grassy plants.

The aflatoxin B1 (AFB1) adsorption properties of several lignins isolated by the Pepper's method from grassy plants: Helianthus tuberosus (LS-1), Atriplex patula (LS-2), Rhododendron tomentosum (LS-3), Althaea officinalis (LS-4), Lavatera (LS-5), and from wood of spruce Pícea (LS-6) were studied. The adsorption was conducted in vitro in the modeled conditions of the gastrointestinal tract. The correlations between the values of adsorption-desorption and the parameters of surface-porous structure and chemical structure of the lignins were established.
