The present invention pertains to high protein, micellar casein-containing nutritional liquids enriched with polyphenols and a method of their production. The invention particularly provides such high protein liquids having a reduced viscosity and a reduced tendency to cold-gelation.

The present invention relates to a method (200) for producing a heat-treated concentrated dairy product (cdp). The method (200) comprising the steps of passing (210) the dairy product (dp) under a pre-determined pressure through a reverse osmosis, RO, filter (110) at a first temperature, the pre-determined pressure being sufficient to allow reverse osmosis, thereby concentrating the dairy product (dp). Preheating (230) the concentrated dairy product (dp) at a second temperature for a second period of time to stabilize the concentrated dairy product (dp). Homogenizing (240) the stabilized concentrated dairy product (dp) to reduce a size of particles in the stabilized concentrated dairy product (dp). Heating (250) the stabilized concentrated dairy product (dp) at a third temperature for a third period of time to reduce microorganisms in the stabilized concentrated dairy product (dp), thereby forming the heat-treated concentrated dairy product (cdp).

Disclosed are methods for preparing aseptic dairy compositions having at least 35 wt. % solids, and often from 40 to 50 wt. % solids, by subjecting a dairy product to forward osmosis following by a heat treatment step. The heat treatment step can include UHT sterilization via direct steam injection or direct steam infusion. Subsequently, the aseptic dairy composition can be dried to form a dairy powder composition.

Disclosed is a method for making yogurt products of viscosities from about 50 centipoise to about 200,000 centipoise, the yogurt products having a total protein content of at least about 12 percent, the whey protein in the product being primarily in the undenatured state (at least about 75% undenatured). Also disclosed are products made by the method, such as yogurt drinks comprising at least about 12 percent total protein, wherein at least about 75% of the whey protein is in the undenatured state.

The present invention features animal feed comprising an effective amount of carotenoid-oxygen copolymer for use in methods for: (i) ameliorating one or more symptoms of subclinical mastitis; (ii) reducing the frequency of subclinical mastitis progressing to full clinical mastitis; (iii) reducing bacteria count in colostrum or milk of a mammal; (iv) reducing physiological stress of a mammal; (v) improving reproductive performance of a mammal; and/or (vi) improving the health of offspring of a mammal. The invention also features a method for producing pasteurized milk from a mammal which has been fed the animal feed supplemented with carotenoid-oxygen copolymer.

Disclosed are processes for producing cultured dairy products, such as yogurt, that are shelf-stable without refrigeration. Such processes can include contacting a milk base having from 0.5 to 1.9 wt. % milk sugar with a lactic acid bacteria culture and aseptically packaging in a container, followed by storage under conditions suitable to result in a pH of less than 4.7.
