Gerhard Norbert Zehentbauer 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).

  • Patent number: 8865192
    Abstract: The present invention relates to flavor oils including mint-, fruit- and spice-type flavors that are specially processed to substantially eliminate low-molecular weight sulfur compounds, in particular dimethyl sulfoxide (DMSO), which has been found to be the main precursor of malodorous species such as dimethyl sulfide and methyl mercaptan. These malodorous species are produced via oxidation-reduction reactions involving such sulfur-containing compounds present in flavor oils. A preferred processing method is an aqueous-washing process, which has advantages of being simple, inexpensive and easy to implement while importantly avoiding the problems of typical processes including non-selective removal of desirable components and subjecting the flavor oils to extreme conditions that may destroy other components and result in undesirable changes in flavor or odor character.

  • Publication number: 20110212240
    Abstract: Processes for isolating bitter compounds for use in food and beverage products entailing contacting a bitter compound composition with an adsorbent to adsorb bitter compounds from the bitter compound composition, desorbing the bitter compounds from the adsorbent to obtain a bitter compound isolate, and adding the bitter compound isolate to a food or beverage product to enhance the flavor thereof.

  • Patent number: 8007771
    Abstract: The present invention relates to oral care compositions comprising stannous ions, a mint-type flavor oil, a protectant component that prevents generation of off odor and off taste in the composition, and orally acceptable carriers. The mint-type oils include peppermint, spearmint and corn mint. Suitable protectant components include copper salts and carbonyl compounds such as ascorbic acid; cis-jasmone; 2,5-dimethyl-4-hydroxy-3(2H)-furanone; 5-ethyl-3-hydroxy-4-methyl-2(5H)-furanone; vanillin; ethyl vanillin; anisaldehyde; 3,4-methylenedioxybenzaldehyde; 3,4-dimethoxybenzaldehyde; 4-hydroxybenzaldehyde; 2-methyoxybenzaldehyde; 4-methoxybenzaldehyde; benzaldehyde; cinnamaldehyde (3-phenyl-2-propenal); hexyl cinnamaldehyde; ?-methyl cinnamaldehyde; ortho-methoxy cinnamaldehyde; ?-amyl cinnamaldehyde; and combinations thereof. The oral care composition may be a dentifrice.
