Disclosed is a process for the co-manufacture of ingredients having food and beverage applications, using potatoes as starting material. The process comprises six steps. The first step is a cutting and dipping of washed raw potatoes in an anti-oxidant solution. The second step is an extraction of undiluted juice free of starch and fibers from a purée made from the anti-oxidant-dipped raw potatoes. The third step is a concentration and enzymatic treatment of the juice. The fourth step is a heating of the juice to specific temperatures to cause precipitation of proteins and separation of precipitated protein therefrom. The fifth step is a thermal browning of the clear juice. The sixth step is an adjustment of the final pH of the juices of the fourth and fifth steps and a blending of these juices in ratios appropriate for intended use.
