The invention concerns a process for the treatment of a sweet whey material containing cGMP (caseinoGlycoMacroPeptide), said process comprising the following steps: Decationising the sweet whey material so as to obtain sweet whey material having a pH value of 1 to 4.5; Treating said sweet whey in a fluidized bed reactor comprising a specific volume of an anionic resin, at a temperature between 10 and 18 C., wherein said sweet whey contacts said resin for a sufficient amount of time so that the resin absorbs between 52% and 58% of the cGMP present in the sweet whey; andRecovering a protein material. Advantageously, the protein material is suitable for hypoallergenic infant formulae.

A coated particle may include a food particle coated by a carbohydrate. The coated particle may have an average particle size from about 10 m to about 250 m. The food particle may include a relatively bitter component (e.g., cocoa) and a protein component (e.g., whey protein, soy protein, rice protein, fava bean protein, and/or milk protein). A weight ratio of bitter component to protein component may be about 3 or greater. The food particle may also include a starch, such as rice starch. Additionally, the coated particle may have a surface area fraction of the carbohydrate that is greater than an average weight fraction of the carbohydrate. For example, the surface area fraction of the carbohydrate may be from about 30% to about 80%. In addition, the coated particle may have a substantially non-spherical and irregular shape. The coated particle may be prepared via a spray drying process.

A method for preparing a modified whey protein concentrate (WPC) or whey protein isolate (WPI) is described. It involves (a) providing an aqueous WPC or WPI solution having a protein concentration of 15-50% (w/v), at a pH of 4.7-8.5; (b) heat treating the solution to more than 50 DEG C, for a time that allows protein denaturation to occur the heat treating comprising heating the solution while under conditions of turbulent flow. At the end of the heat treatment, the heat treated material may be promptly transferred to a drier or to be mixed with other ingredients. The heat-treated WPC or WPI is not subjected to a mechanical shear process prior to the transfer other than where liquid is converted into droplets to facilitate drying. The modified WPC is useful in the manufacture of food and drinks where a high protein content is desired without undesirable changes in texture.

Provided are a protein powder capable of increasing the amount of protein ingested, a protein-containing composition, a method for producing a food, a method for producing a protein powder, a method for producing a protein-containing composition, a method for evaluating a protein powder, and a method for evaluating a protein-containing composition. A water droplet is adhered to the surface of the protein powder which was in a leveled state to measure a contact angle. The contact angle is measured from the time point when the water droplet contacts with the protein powder, and it is determined whether or not the contact angle is 90 or less within 60 seconds. The protein powder having a contact angle of 90 or less within 60 seconds is evaluated as a protein powder that is easy to eat without water.

Use of an -lactalbumin enriched whey protein extract as a source of osteopontin in a synthetic nutritional composition for an infant or child wherein, the -lactalbumin enriched WPE is obtained by a process comprising: a. acidifying a whey protein product to pH 4 or below b. forming a low calcium whey protein product by concentrating the proteins in the acidified whey protein until the calcium to protein ratio is less than about 0.001 and, c. Precipitating -lactalbumin from the low-calcium whey protein product, wherein said precipitating step includes the sub-steps of: X. diluting the low-calcium whey protein product, XI. adjusting the pH of the diluted low-calcium whey protein product to between 4 and 5 to form a precipitate and soluble proteins, and XII. Separating the precipitate proteins from the soluble proteins.

The present invention concerns methods of isolating milk proteins. Methods of the invention include charged ultrafiltration processes that use variations in pH to further separate protein species.

The present invention provides a method for the production of whey proteins in a single step process using combination of chromatography and membrane filtration technique, comprising treating cotton cloth with a mixture of chlorosulphonic acid and chloroform and then subsequently treating it with chloroform, dilute NaOH, glycine and water to recover modified cotton cloth as the product, thereafter fixing product in a membrane filtration device equipped with modified flow pattern and then equilibrating it with equilibration buffer, followed by loading of whey for adsorption of protein on the product and washing of the product with equilibration buffer, thereafter elution of adsorbed proteins with elution buffer, and then regeneration of the product by treating it with dilute HCl and water to reuse the product.

The present invention is directed to a foam comprising rapeseed protein isolate, a second protein selected from the group consisting of whey protein, casein or milk and water and a process for making the foam. Also disclosed are the use of the foam in food products and food products comprising the foam.

The present invention pertains to a new type of denatured whey protein compositions having a low content of soluble whey protein and a high content of protein and to a method of producing them. In particular, the present invention pertains to the new type of denatured whey protein compositions having a low content of soluble whey protein, a high content of protein and low content of fat and to a method of producing them. The invention furthermore pertains to products containing the high protein denatured whey protein compositions, particularly high protein, acidified dairy products, and additional uses thereof.

The invention discloses a method for producing a deodorized goat/sheep milk, which method comprises purifying fresh goat/sheep milk or goat/sheep full cream, wherein the material is subjected to a carbon dioxide treatment during the purification, and the carbon dioxide treatment comprises: introducing carbon dioxide into the material, then refrigerating the material, and removing carbon dioxide. The producing method of the invention is simple, and has a good effect of removing muttony odor of goat/sheep milk. The present invention also discloses a deodorized goat/sheep milk and a deodorized goat/sheep milk product.
