  • Patent number: 6416796
    Abstract: The invention provides a dairy composition containing a complex of a casein-complexing whey protein digestion product and casein micelles, and methods for their preparation. Also provided are the digestion product and methods for its preparation. The digestion product is provided by the action of a non-rennet protease on whey protein, such that the digestion product remains with the curds when a composition including the complex is subjected to a renneting process that provides curds and a supernatant. The resulting curds also include casein degradation products. The non-rennet protease is the bacterial protease Novo SP 446. The invention additionally provides a cheese composition and a cheese product obtained by renneting a dairy composition containing the casein-complexing whey protein digestion product described herein and casein micelles. The resulting cheese composition includes whey protein digestion products and casein degradation products.

  • Patent number: 6270814
    Abstract: The present invention provides a process cheese product made with a cheese and dairy liquid that includes casein, whey protein, and lactose, wherein at least a portion of the casein and/or whey protein in the dairy liquid is crosslinked via &ggr;-carboxyl-&egr;-amino crosslinks prior to being combined with the cheese, and wherein the lactose in the process cheese product remains dissolved in the aqueous phase upon storage. According to the invention, this product is provided by a process that includes the important step of contacting the dairy liquid with a transglutaminase for a time, and under conditions, sufficient to crosslink at least a portion of the casein and/or whey protein to provide crosslinked protein conjugates in the dairy liquid. The invention furthermore provides the process for making the process cheese product. Advantageously, the process permits replacing part of the cheese proteins with the crosslinked proteins of the dairy liquid.

  • Patent number: 6242036
    Abstract: The present invention provides a cheese curd that contains protein products originating from a dairy liquid containing casein and whey protein. In order to obtain the cheese curd, the dairy liquid is acted upon by a transglutaminase and a non-rennet protease, resulting in a substantial proportion of whey protein products being retained in the cheese curd. The invention also discloses a method of making the cheese curd that retains a substantial proportion of whey protein products. This invention further provides a cheese product, such as a soft cheese, a semi-soft cheese, or a hard cheese, that contains protein products originating from a dairy liquid containing casein and whey protein, and a method of making the cheese product.

  • Patent number: 6224914
    Abstract: The present invention provides a cheese curd containing a substantial proportion of whey protein products and curded proteins originating from a dairy liquid containing casein, as well as a process for making the cheese curd. The process includes the significant step that a dairy liquid fortified with whey protein is contacted with a transglutaminase to provide a modified dairy liquid containing whey protein products. The modified dairy liquid is then blended with a second dairy liquid and renneted to provide the curd, whereby a high proportion of whey protein products is retained in the curd. The curd can be used to prepare cheese products, including soft, semi-soft, and hard cheeses, where the cheese products contain a substantial proportion of whey protein products and curded proteins originating from dairy liquids.

  • Patent number: 6214404
    Abstract: The present invention discloses a method of preparing a process cheese containing lactose wherein the cheese remains free of lactose crystals. The method includes a step in which a dairy liquid is heated at a temperature, and for a duration in time, that are sufficient to inhibit or prevent crystallization of the lactose after formation of the process cheese. The ratio of dairy liquid to cheese is from about 1:1 to about 3:1 by weight. The invention additionally discloses the lactose-containing process cheese stabilized against the formation of lactose crystals, prepared by the process of the invention.

  • Patent number: 6057135
    Abstract: D-tagatose is manufactured from cheese whey and/or milk. The cheese whey and/or milk is hydrolyzed to prepare a mixture comprising galactose and glucose. Galactose is separated from the glucose by fermentation and subjected to isomerization using L-arabinose isomerase, thereby producing D-tagatose. The D-tagatose can be used as a reduced calorie food sweetening and bulking agent, as an intermediate for the synthesis of optically active compounds, and as an additive in detergent, cosmetic and pharmaceutical formulations.

  • Patent number: 5445836
    Abstract: A process for producing a tea extract which forms little or no haze when stored at refrigeration temperatures. The process comprises incubating a mixture of oxidase, tannase and tea extract, and then separating insoluble solids from the tea extract. The tea extract is preferably a concentrate which is subsequently diluted to provide a ready-to-drink beverage. Haze which develops on cold storage of the extract or of tea beverages prepared from the extract is significantly reduced.

  • Patent number: 5417990
    Abstract: Multi-component (e.g., multi-layered) and multi-colored gelled products, such as gelatin dessert gels, are prepared using water-soluble colorants and complexing agents for the colorants which will prevent the colorant from migrating within the gelled layer. The complexing agents are polyamino acids and protein materials which fluoresce with ANS.

  • Patent number: 4393085
    Abstract: The object of the present invention is to provide an improved process for preparing a dog food comprising farinaceous and meaty ingredients.This invention recognizes for the first time that the palatability of dog food can be improved when at least a portion of the farinaceous ingredients are subjected to both an amylase and protease enzyme digestion and intermixing an enzymatically modified proteinaceous material to form a reaction slurry mixture. The resulting combined reaction slurry mixture can be incorporated into the dog food by coating it on the surface or admixing it with the other dog food ingredients and thereby incorporating it internally. Preferably, the combined reaction slurry is admixed with the other ingredients to form a plastic mass which is then shaped and expanded by extrusion.
