2016.02 (BIOTIN) FINAL ACTION REVIEW FOR ERP USE ONLY DO NOT DISTRIBUTE

200

In view of the absence of a standard analytical procedure for total biotin, the biotin working group of SPIFAN activity mooted by AOAC International has developed a Standard Method Performance Requirements (SMPR 2014.005) in search for a candidate method to be considered as a global dispute resolution standard. The AsureQuality Auckland Laboratory has developed a method to facilitate a specific, precise, accurate and robust procedure for the analysis of biotin and biocytin from Infant Formula and Adult / Pediatric Nutritional Formulas (1-8). The method meets the SMPR and also has an assured limit of quantification of 0.1µg/100g (1ppb) based on a simple mathematical relationship between lowest standard and dilution. The method involves immunoaffinity column (R-Biopharm Rhone, EASI-EXTRACT biotin column or equivalent) clean-up and extraction followed by LC - UV set at 200nm. The laboratory has carried out extensive Single Laboratory Validation (SLV) study following SPIFAN SLV guidelines (Appendix L: AOAC International) using SPIFAN kit and NIST SRM 1849a. The SLV along with the method was reviewed by the AOAC SPIFAN expert review panel (ERP) in 2016 and approved for First Action Official Method of Analysis (OMA) 2016.02. The objective of the Multi Laboratory Testing (MLT) study was to establish the precision and accuracy of the method in various laboratories to demonstrate the suitability of the method as an international reference method with endorsement as AOAC Final Action, and possible adoption by ISO and Codex. The study was chaired by Dr George Joseph from AsureQuality New Zealand and is monitored by AOAC International (SPIFAN) Official Method Board through its delegated personnel. The study is divided in two parts: method set up and qualification of participants (Part 1) and multi laboratory testing by the qualified participants (Part 2). Extensive campaign was carried out through AOAC and ISO/IDF meetings / contacts to recruit potential laboratories for the MLT. Formal invitation has been sent to more than 30 laboratories around the world by the study director and 15 laboratories agreed to participate. Delivery of SPIFAN matrices to a laboratory in Thailand was failed / cancelled due to issues with the recipient’s / country’s import clearance requirements. Two laboratories could not progress at all with the MLT within the time frame due to inadequate resources or alternative problems. The details of the remaining 12 laboratories from 10 different countries participated in the MLT study (Table 2016.02A) Collaborative Study (Multi Laboratory Testing)

The study was carried out using SPIFAN II matrices, which represent most of the products in the scope of the project (Infant Formula and Adult Nutritionals made from any combination of milk, soy, rice, whey, hydrolysed protein, starch and amino acids, with and without intact protein). Fourteen different product types were provided to each laboratory which includes two practice samples and 12 samples for multi laboratory testing over two separate days. Two split samples of each matrix were included in the package as blind coded duplicates to analyse on the same day. The sample details are summarised in Table 2016.02B
