2.6 Water Activity Standard: Background Information
Guidelines: Follow the calibration and operations instructions given by the
water activity testing equipment manufacture, placing the appropriate
quantity of coffee beans into the device.
Caveat 1: Any analytical determination is at most as good as the sampling
step that precedes it.
Caveat 2: Water Activity (aw) determinations cannot assure that previous
infection and spoilage did not occur on the green coffee in the past.
Monitoring plans for extant presence of mycotoxins should always be in place
throughout the farm-to-roaster supply chain.
