A pulse protein product, which may be an isolate, produces heat-stable solutions at low pH values and is useful for the fortification of acidic beverages such as soft drinks and sports drinks without precipitation of protein. The pulse protein product is obtained by extracting a pulse protein source material with an aqueous calcium salt solution to form an aqueous pulse protein solution, separating the aqueous pulse protein solution from residual pulse protein source, adjusting the pH of the aqueous pulse protein solution to a pH of about 1.5 to about 4.4 to produce an acidified pulse protein solution, which may be dried, following optional concentration and diafiltration, to provide the pulse protein product.

Protein-containing beverages are described. The beverages may include water and 2 wt. % to 8 wt. % protein (based on the total weight of the beverage). The protein in the beverage may include whey protein. The whey protein has at least 12 wt. % of the branched-chain amino acid leucine (based on the total weight of the whey protein). The beverage may also include casein protein. Methods of making protein-containing beverage products are also described. The methods may include providing a protein-containing aqueous mixture, homogenizing and pasteurizing the protein-containing aqueous mixture, and bottling the homogenized and pasteurized protein-containing aqueous mixture to form the protein-containing beverage product. The protein-containing aqueous mixture may include casein protein, and whey protein having at least 12 wt. % leucine (based on the total weight of the whey protein).
