On page 717 of the RESULTS AND DISCUSSION

the following paragraph:

The ORP of E-BF ranged from –341.7 mV to –493.7 mV. Meanwhile, the ORP of BF, which was not electrolyzed, was totally higher (the mean value was approximately 329.5 mV) than that of E-BF (the mean –429.7 mV) throughout the entire experiment.

Should have been shown as:

The ORP of E-BF ranged from –582.7 mV to –734.7 mV. Meanwhile, the ORP of BF, which was not electrolyzed, was totally higher (the mean value was approximately 129.5 mV) than that of E-BF (the mean –670 mV) throughout the entire experiment.
