  • Patent number: 8906957
    Abstract: A process is provided for preparing (1) a first composition obtained by extracting a plant material with a single phase mixture of water and at least a first organic solvent under agitation so as to obtain a first extract rich in polyphenol oligomers, wherein the first composition is the first extract, and (2) a second composition obtained by extracting at least a portion of the first extract with a biphasic mixture of water and at least a second organic solvent under agitation so as to obtain a second extract rich in polyphenol monomers, dimers, and trimers, wherein the second composition is the second extract. Food products, mendicants, and cosmetics containing the first composition or the second composition are also provided.
    Type: Grant

  • Patent number: 7329424
    Abstract: Process for manufacturing cheeses and other dairy products, and the resulting products, in which lactobionic acid is added, or generated in situ, in combination with a dairy component in the course of the process. The lactobionic acid can be used as the sole acidulent for direct acidification of the cheese, or in conjunction with reduced amounts of lactic acid culture. When the lactobionic acid is generated in situ during cheese manufacture according to the invention, a lactose oxidase is used in one embodiment to convert lactose intrinsically present in the dairy liquid ingredient(s) into lactobionic acid. The organoleptic attributes of the cheeses made using lactobionic acid as an ingredient are satisfactory and fully suitable. The process can be applied to the production of a wide variety of cheeses, including, for example, cream cheeses, hard cheeses such as cheddar, UF cheeses, process cheeses, cheddar cheeses, and so forth.
