AOAC INTERNATIONAL (AOAC) invites method developers to submit methods for consideration and possible evaluation through the AOAC Official MethodsSM program. Prospective methods must be able to determine Vitamin C in all forms of infant formula, follow-up formula, baby food, adult/pediatric formula, complementary food supplements, nutritional supplements for pregnant women and nursing mothers, and sports nutrition food.
For the purpose of this call for methods, vitamin C is defined as the sum of L-ascorbic acid or its salts, and dehydro ascorbic acid. Reported as vitamin C (L-ascorbic acid) according to the draft Standard Method Performance Requirements (SMPR®). D-ascorbic acid (erythorbic acid) and ascorbyl palmitate are excluded from the definition of vitamin C for the purposes of this Call for Methods.
The objective of this project is to select, evaluate, and validate reference methods that can be used for dispute resolution. Acceptable methods must be reliable and reproducible when used by trained analysts in accredited laboratories.
Reference the draft SMPR for definitions of the various applicable commodities and the proposed method validation requirements for parameters such as analytical range, limit of quantitation, recovery, repeatability and reproducibility, system suitability and reference materials. Any analytical technique that meets the method performance requirements is acceptable.
Interested method developers must provide their method and data demonstrating that the method can meet the performance requirements.
Method authors may submit methods for review to the Official Methods of Analysis℠ (OMA) program.
