Acidic, alcohol:free beverages fortified with protein - by adding whey protein concentrate and opt. defatted dried milk

摘要

Method for fortifying acidic, alcohol-free beverages with proteins to give a stable, turbid suspension comprises mixing with a protein fortifier (A). (A) consists either of a cheese-whey protein concentrate (I) for a final drink pH of 3.1-3.9; or of 50-95% (I) plus 5-50% defatted dried milk (II) for a final drink pH of 3.1-3.7 (% expressed on total of (I) plus (II)). Pref. with (I) only pH is 3.8 plus or minus 0.05 and for (I) + (II) it is 3.5 plus or minus 0.5. Fortifiers contg. (I), esp. 75-90%, and (II), esp. 10-25%, are claimed. (I) is esp. pref. an acid-coagulated whey, specifically a neutralized and pasteurized concentrate from cottage cheese prodn. (II) is esp. made by intense heating of milk. For drinks such as cola, root-beer, citrus beverages etc., opt. carbonated. The fortified drinks pref, contain 0.1-1 wt.% proten (as Kjeldahl N).
