Electroheating apparatus and methods utilize a dielectric structure defining a conduit course of relatively small cross-sectional area and electrode surfaces of relatively large area so that the electrical current density in a region of the conduit remote from the electrodes is substantially higher than the current density at the electrode surfaces themselves. The system uses relatively high electrical resistance and relatively high voltages to provide substantial heating effect with low total currents. Foods such as liquid egg can be pasteurized.

[ What is claimed is:] [1.] A method of continuously electroheating a proteinaceous biological product comprising the steps of:conductively dissipating in a course substantially continuous alternating electrical energy in the product between a first electrode surface and a second electrode surface at a rate of at least about 40.degree. C./sec in an electric field of less than about 925 volts/cm such that a length corresponding to a shortest path through the course from any first point on the first electrode surface to any second point on the second electrode surface is substantially the same for any pair of first and second points, so that the electrical current density near said electrodes is substantially uniform and wherein said step of dissipating is performed until the product is at least pasteurized without substantial electrolysis and coagulation of, and arcing within, the product; andrapidly cooling the product immediately after said step of electroheating before detrimental coagulation occurs.
