A study was undertaken to compare juice yield from electroplasmolysis treated (EP, US Patent 4 723 483) apple pomace with other standard methods of juice extraction, enzyme treatments, a heat treatment and a control. On a 15‐min press cycle yields among treatments were similar, with the heated mash sample and the EP sample slightly higher than the others. Rate of juice expression from press cake was very different between treatments, with the heat treated sample and the EP being among the highest.
