  • Tobacco products or materials resembling tobacco products containing natural substances having an antioxidative effect and processes for the preparation thereof
    Patent number: 5944026
    Abstract: Smokable products made of tobacco and/or another smokable material, which comprise natural substances having an antioxidative effect and/or naturally identical synthetic products thereof. These natural substances are selected according to the invention from hydroxycinnamic acids and their esters and depsides, plant phenols which can be derived from hydroxycinnamic acids, polymers of hydroxycinnamic alcohols, further natural substances of plant origin which have antimutagenic and aromatizing properties and are combined with vitamins, their precursors and/or derivatives having an antioxidative effect, and further vitamins having an antioxidative effect which are complexed with eukaryotic cell cultures. Processes for the preparation of products of this type are furthermore described. Compared with conventional smokable products, the products have a distinctly decreased risk potential.

  • Coffee and process for the production thereof
    Patent number: 5888549
    Abstract: Roasted coffee with an increased chlorogenic acid content of more than 2.8% by weight or instant coffee powder with an increased chlorogenic acid content of more than 8.5% by weight have a better compatibility. The increased chlorogenic acid content is achieved either by adding chlorogenic acid or by extracting raw coffee and adding the optionally concentrated extract to the roasted coffee.

  • Process for separating and removing caffeine and chlorogenic from raw coffee and from one another
    Patent number: 5045334
    Abstract: A process for separating caffeine from an aqueous raw coffee extract by means of gel chromatography is described, in which simultaneously the chlorogenic acids can be separated if desired. The inventive process makes it possible to obtain in a simple manner decaffeinated coffee, optionally with a reduced chlorgenic acid content.
    Type: Grant

    Date of Patent: September 3, 1991
    Assignee: Kaffee Handelsgesellschaft mbH
    Inventors: Reiner Kopsch, Henning Lutz, Claus Gosswein
  • Process for separating and producing chlorogenic acid
    Patent number: 4872987
    Abstract: Chlorogenic acid can be separated and produced as free acid or as salts thereof from plant raw material extracts by means of gel permeation chromatography on cross-linked modified polysaccharides, especially on dextrans. To obtain the free acid, the aqueous extract must be adjusted to a pH in the range of about 2 to 2.8. By use of a column of sufficient length the isomeric 5-, 4- and 3-chlorogenic acid can also be separated by the process of the invention.
