Hey all,
Just got a Mettler-Toledo optical DO meter and am wondering about SOP for testing at various points (e.g. pre-filter, post-filter, brite, and package.)
Main question is: how long does it take for levels to drop in cold beer? Do we need to sample cans immediately off the line? Does anyone have any literature on reaction rates, oxidation products, etc?
I'm asking because we can pull a can from the line and get a peak reading of around 80 ppm, but that drops to 10-15 in less than a minute. Is that a realistic rate of oxidation?
Any reading suggestions would be appreciated.
Cheers,
Mike
