Provided herein are compositions and methods for producing milk proteins, which allow for safe, sustainable and humane production of milk proteins for commercial use, such as use in food compositions. The disclosure provides recombinant fusion proteins comprising at least first protein and a second protein, wherein at least one of the first protein and the second protein is a milk protein, or fragment thereof: The disclosure also provides methods for producing the recombinant fusions proteins, and food compositions comprising the same.

The invention relates to a method of producing a food or beverage product, comprising the steps of: providing an ingredient composition comprising, micellar caseins and whey proteins and having a pH of 6.1-7.1 and a concentration of 1-15 wt. % of proteins, and wherein the ingredient composition has a casein to whey protein ratio of 90/10-60/40, adding 3-25 mM divalent cations to provide a concentration of 3-8 mM free divalent cations in the ingredient composition, homogenising the ingredient composition; and subsequently pasteurising and stirring the ingredient composition at a temperature of 80°-100° C. for a period of 0.5-3 min to form agglomerated proteins comprising caseins and beta-lactoglobulin from the whey proteins, the agglomerates having a size of 5-50 microns as measured by D(.sub.4,3) mean diameter. The invention relates also to a food or beverage product comprising aggregated proteins comprising micellar casein and whey protein aggregates, wherein the product has a pH of 6.1-7.1, a concentration of 6-40 wt. % milk solids, a casein to whey protein ratio of 90/10-60/40, and a concentration of 3-8 mM free divalent cations, and wherein the agglomerates having a size of 5-50 microns mean diameter D(.sub.4,3) as measured by laser diffraction.
