OK here is a thought. When I added the food slurry to the "off line" sample it had already been dosed with H2O2 and it interfered with the time to minimum...just a quick thought.
Just a comnent on drop and rise times.
The ORP change when mixing fluids will depend on how readily the chemicals can actually react with one another. Some react almost instantly when they encounter one another (say, Cu+ and Fe+++) and some may react quite slowly in the absence of catalysts (say, O2 and ascorbic acid). Thus, the rate of change may be impacted by kinetic factors of the actual electrochemical reactions involved.
