Abstract High protein, low calorie dairy spread water-in-oil emulsions having a 20-65% aqueous phase are produced employing as the aqueous phase a protein concentrate having a 13-20% protein content and obtained as a by-product in the manufacture of butter from sour buttermilk, buffered at 6-7 with citrate and phosphate buffering salts, and as the fat phase butter oil optionally mixed with a polyunsaturated vegetable oil, emulsifying the aqueous phase into the fat phase at 38°-50° C., flash pasteurizing the emulsion, optionally adding flavoring agents before or after emulsifying and pasteurization, and then cooling the emulsion, first to 20°-14° while working the emulsion as it solidifies, and then to storage temperature, e.g., 12°-8° C.
A dairy based high protein low calorie water-in-oil emulsion spread which is spreadable at refrigerator temperatures, having a 20-65% aqueous phase with an 11 - 18% protein content provided by the protein concentrate obtained from buttermilk soured bacteriologically and buffered with citrate and phosphate buffers to a pH of between 6 and 7 whose fat content is provided by a mixture of butter oil and a polyunsaturated vegetable oil.
