US Patent:

6638555, Oct 28, 2003

Filed:

Oct 19, 2001

Appl. No.:

10/027841

Inventors:

Virginia R. Bank - Boulder CO
David T. Bailey - Boulder CO
Johan T. van Leersum - Cincinnati OH

Assignee:

Hauser, Inc. - Longmont CO

International Classification:

A23L 122

US Classification:

426534, 426599, 424736

Abstract:

A method of preparing storage-stable, citrus-flavored compositions containing comprising citral or a citral derivative as the flavoring agent and a plant extract as the stabilizing agent. The plant extract inhibits the formation of p-methylacetophenone, thereby preventing the development of off-flavors and off odors and increasing the shelf life of the composition.

Assignee:

Hauser, Inc. - Boulder CO

International Classification:

A23L 127

US Classification:

426262

Abstract:

An improved pigment composition containing an anthocyanin pigment and a pigment-improving agent selected from the group consisting of flavonoid glycuronides, flavonoid glucuronides, and caffeic acid derivatives. The pigment-improving agents deepen and improve the intensity of the anthocyanin pigment and increase its stability in the presence of light, heat and/or pH.

Assignee:

Hauser, Inc. - Boulder CO

International Classification:

C07C 6334

US Classification:

562467

Abstract:

A process for the extraction and isolation of concentrated carnosic acid from plant matter of the Labiatae family including contacting the plant matter with a water-miscible solvent to form a plant extract and adjusting the pH of the plant extract to a level between 7 and 10 while adding water in an amount sufficient to cause precipitation of impurities while retaining the carnosic acid salt in solution. The impurities are separated and the remaining aqueous solution is acidified to precipitate a highly purified carnosic acid product which is essentially odorless, flavorless and colorless.
