Demetrius Michos has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method of removing proteins from beverages using crosslinked tannin/inorganic oxide composites
    Patent number: 5912037
    Abstract: Epoxy-polymerized tannin/inorganic oxide composite particles are obtained by polymerizing the tannin with a polyepoxy crosslinking agent in situ on inorganic oxide particles. The compositions of the invention are capable of achieving the performance of tannin in beverage treatment applications without tannin's associated filtration disadvantages.
    Type: Grant
    Filed: February 2, 1998
    Date of Patent: June 15, 1999
    Assignee: W. R. Grace & Co. -Conn.
    Inventor: Demetrius Michos
  • Polyamide compositions for removal of polyphenols from liquids
    Patent number: 5856429
    Abstract: Amide-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.
