Methods and systems for making a high-purity -lactalbumin composition are described. The composition may be made by providing a whey protein mixture, and adding an alkaline solution to the mixture to make the mixture alkaline and promote the aggregation of -lactoglobulin proteins. The alkaline whey protein mixture is filtered into a -LG aggregate composition and a -LA enriched composition. A final -lactalbumin enriched composition sourced from the -LA enriched composition is dried into the high-purity -lactalbumin composition (a powdered dairy composition) that is at least 70 wt. % -lactalbumin on a protein basis. A protease enzyme may optionally be added to the -LA enriched composition to form an enzymatically treated -LA enriched composition that becomes the source of the final -lactalbumin enriched composition.

The invention relates to a product comprising a container and a composition comprising a high amount of whey protein, in the container. The container is a flexible container and the composition presents, in the container, a modified, controlled texture.

A method of producing microparticles by spray drying comprises the steps of providing a spray-drying feedstock solution comprising water, a volatile divalent metal salt, weak acid, 5-15% dairy or vegetable protein (w/v) and 1-20% active agent (w/v). The feedstock solution is adjusted to have a pH at which the volatile divalent metal salt is substantially insoluble. The feedstock solution is then spray-dried at an elevated temperature to provide atomised droplets, whereby the volatile divalent metal salt disassociates at the elevated temperature to release divalent metal ions which crosslink and aggregate the protein in the atomised droplets to produce micro-particles having a crosslinked aggregated protein matrix and active agent dispersed throughout the matrix.

The present invention relates to a method for manufacturing a modified whey composition, the method having a liquid preparation step of preparing a raw material whey liquid using a whey composition containing whey protein, and a heating step of subjecting the raw material whey liquid to a heat treatment, wherein the liquid preparation step includes a treatment of adding an alkali to the whey composition, the pH of the raw material whey liquid is from 6.8 to 8.0 and the protein concentration in the liquid is not more than 1.3% by mass, the calcium content of the raw material whey liquid that is subjected to the heat treatment is from 400 to 700 mg/100 g of solids, and the heat treatment is performed under conditions of 80 to 150 C. for a period of 30 minutes to 1 second.
