AOAC ERP Gluten Assays - Dec 2018
OMAMAN‐47: Quantification of Wheat, Rye, and Barley Gluten in Oat and Oats Products SUMMARY OF COMMENTS ER 2 Yes.
Yes, though additional individual data points for wheat and rye would have been beneficial.
ER 3
The method has defined the basis for a rationally and scientifically meaningful collaborative study No. The only data to calculate accuracy of the method comes from reference material of 10 mg/kg gluten. The method should also be validated against the 20 mg/kg gluten reference material and other samples, where possible, used in the study. The results of the collaborative test with 19 participating laboratories showed recoveries ranging from 99 to 137 % (recovery data for specific samples not available) for all three grain sources. Relative reproducibility standard deviations for samples >10 mg/kg ranged from 10 to 53 %. The collaborative study results confirmed that the method is accurate and suitable to measure gluten from all three grain sources, and has demonstrated performance on oat matrices which meets the criteria as specified in SMPR 2017.021. Yes, the data submitted allow evaluating the method against MPCs Does the data collected support the criteria given in the collaborative study protocol? yes

No, but I do wonder if they are able to move this kit to the more "ecological" cocktail extraction, in order to eliminate the 2ME ‐ especially because of the large volume of Cocktail being used per sample.
