Abstract: A carbonated protein beverage composition and a method of making it relate to a beverage prepared using a cold-fill preparation and packaging process and carbonation in the container prior to sealing, providing a protein beverage composition with a protein content of about 2.0% by weight to about 6% by weight protein, carbon dioxide at level of between about 1.6 volumes to about 3.5 volumes, a pH of between about 2.0 to about 3.4, and at least one additional ingredient, wherein both, at the time of packaging of the protein beverage composition and during subsequent storage without refrigeration for a time period of at least 18 months after packaging, substantial solubility of the protein is maintained in the beverage composition, and the protein beverage is essentially free of active microbes known to be harmful to human health in the absence of a preservative, wherein the essentially free from active microbe condition is created by the inactivation of microbes by carbonation.

Abstract: A protein beverage composition and a method of making it relate to a beverage including a protein essentially free of caseinate and derived from an aqueous protein isolate collected from membrane-filtration isolation of the protein and without substantial drying, wherein the protein beverage composition exhibits a pH ranging from about 2.0 to about 4.6. Substantial solubility of the protein is maintained in the beverage composition, and the protein beverage is essentially free of active microbes known to be harmful to human health, both at the time of packaging of the protein beverage and for a time period of at least one year after packaging.
