No. 14/689,291 filed Apr. 17, 2015, which claims priority benefit of U.S. provisional application No. 61/980,881 filed on Apr. 17, 2014 and entitled “Protein-Containing Beverage,” the entirety of which is incorporated by reference herein. 
    
    
     FIELD 
     The current invention is directed to beverages. In particular, the current invention is directed to protein-containing beverages. 
     BACKGROUND 
     Beverages are used to quench thirst, provide nutrients, and to accompany meals and gatherings. While many current commercially available beverages exist, most of the available beverages only provide one of the aspects mentioned above, i.e., thirst quenching or delivery of nutrients. In particular, many beverages that offer nutritional benefits, e.g., protein shakes, do not provide a consumer with a sense of refreshment, i.e., they do not quench a user&#39;s thirst. Accordingly, a consumer would need to consume several different beverages in order to get the benefits of refreshment and nutrition. As could be imagined, consumption of numerous beverages over a course of a day may be difficult, inconvenient, time-consuming and expensive. The present invention is seen to be an answer to this need. 
     SUMMARY 
     In one aspect, the invention is directed to a protein-containing beverage, the beverage comprising: whey protein isolate; malic acid; phosphoric acid; at least one flavoring compound; a mouth feel enhancer; at least one sweetener; a vitamin mixture; and a liquid. 
     In another aspect, the invention is directed to a protein-containing composition comprising: whey protein isolate; malic acid; phosphoric acid; at least one flavoring compound; a mouth feel enhancer; at least one sweetener; and a vitamin mixture. 
     In a further aspect, the invention is directed to a process for making a protein-containing beverage, the process comprising: contacting the composition as described above with a liquid; and mixing the composition and liquid to form the protein-containing beverage. 
     These and other aspects of the invention are discussed in more detail in the description and appended claims.

     The present invention is directed to a protein-containing beverage and a protein-containing composition that is used in making a protein-containing beverage. The protein-containing beverage provides a consumer with nutritional benefits including, for example, vitamins and protein. The protein-containing beverage may also increase a consumer&#39;s metabolism, reduce a consumer&#39;s appetite and increase a consumer&#39;s energy levels. Other yet to be discovered benefits may also inure to the consumer ingesting the protein-containing beverage disclosed herein. 
     In one example, the protein-containing beverage includes whey protein isolate, malic acid, phosphoric acid, at least one flavoring compound, a mouth feel enhancer, at least one sweetener, a vitamin mixture, and a liquid. All of the components, i.e., ingredients, of the protein-containing beverage are appropriate for use in beverages and, if necessary, approved by the relevant regulatory authority, e.g., the Food and Drug Administration (FDA). 
     Whey protein isolate (often referred to as “whey isolate” or “whey protein”) is a dietary supplement and food ingredient created by separating components from milk. Whey protein isolates are defined as having &gt;90% protein on a dry weight basis. It is contemplated that any brand of whey protein isolate may be utilized in the protein-containing beverage. In one embodiment, BiPro® whey protein from BiPro USA, may be used. 
     Malic acid is an organic compound with the formula HO 2 CCH 2 CHOHCO 2 H. Malic acid is a known food additive that is commercially available and contributes to the pleasantly sour taste of fruits. Phosphoric acid (also known as orthophosphoric acid or phosphoric(V) acid) is a mineral (inorganic) acid having the chemical formula H 3 PO 4 . It is a commercially available food additive that is typically available in an 85% aqueous solution, which is colorless, odorless and non-volatile. Phosphoric acid is used to add acidity to foods. 
     Any flavoring compound may be used in the protein-containing beverage in order to impart a desired flavor profile to the beverage. The flavoring compound can be natural or artificial or a combination thereof. Examples of flavoring compounds that may be used in the protein-containing beverage include lime flavor, lemon flavor, strawberry flavor, cherry flavor, raspberry flavor, orange flavor, panela flavor, watermelon flavor, tropical berry flavor, pina colada flavor, grape flavor or a combination of any of the foregoing. 
     The at least one sweetener may be any natural sweetener or artificial sweetener, and may also be a combination of both natural sweeteners and artificial sweeteners. The sweetener may be sucrose, glucose, fructose, sorbitol, mannitol, corn syrup, erythritol, high fructose corn syrup,  stevia , monkfruit, pure cane sugar, saccharin, aspartame, sucralose, acesulfame potassium (acesulfame-K), neotame, or a combination of any of the foregoing. 
     As mentioned above, consumers are looking for a convenient manner to refresh themselves and ingest nutrients. Many consumers lack certain vitamins in their diet and thus look to supplements to obtain such nutrients. Accordingly, in one embodiment the protein-containing beverage includes a vitamin mixture. The vitamin mixture may include one or more types of vitamins that are desired by consumers, such as, for example, Vitamin A (beta-carotene), Vitamin Bp (choline), Vitamin B 1  (thiamin), Vitamin B 2  (riboflavin, vitamin G), Vitamin B 3  (niacin, vitamin P, vitamin PP), Vitamin B 5  (pantothenic acid), Vitamin B 6  (pyridoxine, pyridoxamine, or pyridoxal), Vitamin B 7  (biotin, vitamin H), Vitamin B 9  (folic acid, folate, vitamin M), Vitamin B 12  (cobalamin), Vitamin C (ascorbic acid), Vitamin D (ergocalciferol, or cholecalciferol), Vitamin E (tocopherol), and Vitamin K (naphthoquinoids). In one embodiment, the vitamin mixture includes Vitamin B 3 , Vitamin B 5 , Vitamin B 6 , and Vitamin B 12 . 
     It is also contemplated that the protein-containing beverage includes one or more dietary minerals, such as, for example, calcium, Chloride, Chromium, Cobalt (as part of Vitamin B 12 ), Copper, Iodine, Iron, Magnesium, Manganese, Molybdenum, Phosphorus, Potassium, Selenium, Sodium, and Zinc.
