There is no significant destruction of vitamin C during pasteurization by the Electropure or StamVik processes, with all-aluminum equipment. The factors responsible for protection of the vitamin were: (a) very short heating time, (b) methods of heating, (c) protection from atmospheric oxidation while hot, and (d) min. exposure to metals which catalyse oxidation. Vat pasteurization resulted in a destruction of over 1/2 the natural vitamin content, all milk for pasteurization being taken from the same tank. Vitamin content was determined by 2 series of animal assays and by direct titration.
