Canned tomatoes are an important product worldwide and in
Ohio in particular. Any enhancement would be desirable, especially
the improvement of lye peeling to reduce environmental impact.
Therefore, we hypothesized that ohmic treatment might be a viable
alternative method for tomato peeling. This has proven successful,
and is now a patented technology (Wongsa-Ngasri & Sastry, 2009).
Indeed, tomatoes could be peeled with or without lye. However, a
detailed understanding of optimal treatment conditions is still
necessary. The objective of this study was to investigate the effects
of electric field strength, NaCl concentration, initial temperature of
NaCl, and number of tomatoes on peeling time and peeled tomato
