This data includes all methods that AAFCO includes under Method code 012. One important thing to note is that Free Glucose is not included in the calculation for values supplied by my laboratory to AAFCO and may be the reason for why our values are slightly lower than the Rob Mean. It is still important to note that this method was within one standard deviation from the Rob mean on all of the samples tested. AOAC Research Institute ERP Use Only
