Food Authenticity NTT SMPR (Comments)

Draft AOAC Standard Method Performance Requirements (SMPRs) for Non-Targeted 1 Testing (NTT) of Ingredients for Food Authenticity/Fraud Evaluation of Liquid Raw 2 Bovine Milk; version 2; December 27, 2019 5 AOAC SMPRs® describe the minimum recommended performance characteristics to be used 6 during the evaluation of a method. The evaluation may be an on-site verification, a single- 7 laboratory validation, or a multi-site collaborative study. SMPRs are written and adopted by 8 AOAC using the consensus of stakeholders representing the industry, government, and academic 9 and/or research institutions. AOAC SMPRs are used by AOAC expert review panels in their 10 evaluation of validation study data for method being considered for Performance Tested 11 Methods SM or AOAC Official Methods of Analysis SM and can be used as acceptance criteria for 12 verification at user laboratories. 15 This document contains assessment parameters on the performance of Non-Targeted Testing 16 methods to monitor liquid raw bovine milk for the probable presence of Economically Motivated 17 Adulterants (EMA). 18 19 Intentionally designed to be generic, this SMPR was designed for Non-Targeted Testing (NTT) 20 methods developed to be applicable to the broadest range of potential methods using innovative 21 analytical platforms and chemometric approaches. Methods submitted based on this SMPR must 22 yield binary analytical results ( i.e. “Authentic” or “Not Authentic”). 25 A non-targeted method to be used to evaluate bovine milk for possible EMAs. Any method 26 generating a baseline fingerprint of the authentic material and comparing test sample 27 fingerprints to assess differences will be considered. The final binary result identifies test 28 samples as either authentic or potentially adulterated. This method demonstrates reliability 29 using the requirements listed in this SMPR. 30 31 The scope of the NTT method will be defined by the authentic samples used in generating the 32 baseline fingerprint. 35 Applicability Statement – a general statement about the intended purpose and scope of the 36 method entailing key aspects of expected achievements for the specific situation and 37 circumstances. Key points to cover are the intended matrix, the purpose, and an indication of 38 sensitivity, specificity, and significance (USP Appendix XVIII). 39 40 Authentic Samples – Samples representative of the genuine commodity. Ideally these samples 41 should represent the food’s or ingredient’s variability seen naturally in the commodity. The 42 authentic samples used to generate the product fingerprint will be used to properly define the 43 NTT method testing scope. 44 3 4 1. Purpose 13 14 2. Applicability 23 24 3.
