Method of generating an improved quality foam for a beverage through the use of calcium ions

Disclosed is a method for generating an improved quality foam for a beverage, the method comprising: a) providing at least one foaming source (such as dairy proteins, non-dairy proteins, demineralised whey protein isolate products, low mineralised whey protein isolate products and any combination thereof) ; b) providing a multivalent ion source; c) providing a liquid source separate from the multivalent ion source; and d) combining the foaming source, the multivalent ion source and the liquid source and aerating to produce foam; wherein the multivalent ion source is at least one water soluble multivalent ion source selected from the group consisting of calcium chloride, calcium bromide, calcium lactate, calcium nitrate, calcium acetate, calcium ascorbate and any combination thereof; and wherein the foaming source and the water soluble multivalent ion source are stored as a dry mix together prior to combining with the liquid source.
