AbstractAmide-containing polymers characterized by the presence of piperazine amide and/or substituted piperazine amide in the polymer chain are used as adsorbents to remove polyphenolic compounds from liquids. The compositions are especially useful in combination with protein removal agents such as silica gel or tannin. The amide-containing polymer compositions (alone or in combination with protein removal agents) are especially useful in the stabilization and/or chillproofing of plant derived liquids or beverages such as beer, wine, fruit juice and vegetable juice.
