In cake filtration of apple juice, usage of filter aid increased filtration rates. Precoating the filter medium with diatomaceous earth increased filter medium resistance, but cloudy juice was produced in its absence. There was an inverse relation between filtration rates and resistances. Although these were expected results, they did not agree with most of the present filtration theories. De La Garza and Boulton's “exponential model” of wine filtrations simulated the data satisfactorily. Our results show that the common filtration theories, adapted from the other disciplines, may not be appropriate for food engineering analysis.
