Series or experiments employing laboratory methods of homogenization were run at temperatures or 100°F, 110°F, 120°F, 130°F, 140°F, 150°F, 160°F, and 170°F and with pressures of 1000, 1750, and 2500 pounds at each temperature. In all series, at all temperatures and at all pressures, the results of homogenization indicated a reduction of the titratable ascorbic acid content of the milk processed. The amount of destruction of ascorbic acid was variable, ranging from 7.4 per cent to 14.3 per cent with an average reduction or 11.34 per cent. Supplement experiments, employing commercial experiment and commercial methods corroborated the results obtained in the laboratory. / Master of Science
