The present document describes a process for the preparation of an amino acid supplement formulation and a formulation thereof. The process comprises filtering a clarified whey protein solution with a filter having a molecular weight cut off between about 50 and 300 kDa to obtain a protein solution; dehydrating the protein solution to obtain a powder; and mixing the powder with lecithin. The present document also describes a process for the purification of a whey protein isolate, comprising filtering a clarified whey protein solution with a filter having a molecular weight cut off between about 50 and 300 kDa to obtain a protein solution; and filtering the protein solution with a filter having a molecular weight cut off between about 1 and 100 kDa to obtain a protein solution having at least one of active albumin, beta-lactoglobulin, and alpha-lactalbumin proteins.

The invention relates to a whey protein product having a ratio of whey protein to casein in the range from about 25:75 to about less than 50:50, a total protein content of at least 20% on dry matter basis, and a protein content of about 2.5 to about 8% by weight, based on the weight of the product. The product has a favourable amino acid composition and is especially suitable for athletes. The invention also relates to a method for producing a whey protein product, using microfiltration and ultrafiltration. The whey protein product is composed of the ultrafiltration retentate and a casein-containing material at a ratio of whey protein to casein of about 20:80 to about less than 50:50 and a total protein content of at least about 20% on dry matter basis.

The present invention provides a method for the production of a flavor-enhancing composition, the method comprising the steps of: i) providing a dairy liquid; ii) nanofiltrating the dairy liquid to obtain a nanofiltration permeate; iii) concentrating the nanofiltration permeate by reverse osmosis and/or evaporation to produce a flavor-enhancing composition, the flavor-enhancing composition comprising at least 50 wt % lactose by dry weight and having a K:Na ratio of at least 2:1, wherein nanofiltrating the dairy liquid uses a membrane having a molecular weight cut-off of from 300. Da to 800. Da.

Disclosed are processes for producing high protein, Greek yogurt products. Such processes can include a step of concentrating a skim milk product to produce a protein-enriched milk fraction, which then can be combined with one or more additional milk fractions to form a yogurt base. The yogurt base is inoculated with a yogurt culture and fermented, and at least a portion of the acid whey is removed from the fermented product using a ceramic ultrafiltration membrane system to form the Greek yogurt product.

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.

A shelf stable hydration beverage can be prepared based on a dairy permeate.

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.

Processing of milk raw material produces a dairy salt. Preliminary treatment of the milk raw is carried out, with pasteurization and its concentration by nanofiltration through a filter with a pore size of 0.001-0.01 m, subsequent filtration of the obtained nanofiltration permeate through a membrane module with a pore size of 0.0001-0.001 m of a reverse osmosis unit, electrodialysis of the obtained RO retentate, concentration of the concentrate or its concentration and drying. The dairy salts may be manufactured and used to salt food products, beverages, granulated cottage cheese, potato chips, crackers, and dips. A masking fraction with organic acid, amino acid, fatty acid, and sugar portions successfully hides the off-notes otherwise associated with potassium compositions. Food products salted with any of the dairy salts described herein achieve reduced sodium content without compromising flavor.

Methods for preparation of plant-based whey protein concentrates are provided. Also provided are the plant-based whey protein concentrates made using the methods. The methods utilize an enzymatic reaction to reduce the molecular weight of soluble carbohydrates in a plant-based whey and a single nanofiltration/ultrafiltration and/or diafiltration step to separate soluble non-protein components from the proteins.

A quark matrix having improved taste characteristics is suggested, which is obtainable by (a) subjecting raw milk to heat treatment, separating the cream, (b) subjecting the skimmed milk such obtained to a microfiltration step, obtaining a first retentate R1, which represents a first dairy protein concentrate, and a first permeate P1, (c) subjecting the permeate P1 to an ultrafiltration step and/or a reverse osmosis step, obtaining a second retentate R2, which represents a second dairy protein concentrate, and a second permeate P2, (d) subjecting the permeate P2 to an electrodialysis step, obtaining a salt-depleted diluate D1, (e) combining the diluate D1 with the retentate R1, (f) subjecting the combination product such obtained to heat treatment until denaturation sets in, (g) fermenting the denaturation product such obtained by adding starter cultures and rennet, and (h) adjusting the fermentation product such obtained to defined dry matter and protein contents.
