A method of making a powder of serum extracted from a Greek style yogurt is disclosed. The total solids concentration of the serum is increased to at least 35% by weight to produce a concentrated serum. The concentrated serum is crystallized by adding lactose crystals whose average size is less than 100 microns. The crystallized serum is then spray dried to produce a serum powder. The resulting powder is non-hygroscopic, less likely to form lumps in storage, retains the initial characteristics of the serum and is of sufficiently high quality to be fit for human consumption.

The invention relates to the use of milk derived, denatured retentate in the preparation of milk-based compositions, which may be aerated or non-aerated, comprise a skimmed mild source, and/or have less than 0.5% w/w fat. The milk derived, denatured retentate allows the formation of microbubbles in an aerated skimmed milk composition, and thus retains certain desirable sensory perception characteristics such as a good mouthfeel and perceived thickness.
