NOW Foods Inc.’s Joseph Zhou Receives AOAC’s 2005 Study Director Award

Bloomingdale, IL (September 21, 2005) – AOAC International, the scientific association dedicated to analytical excellence, awarded NOW Foods’ Dr. Joseph Zhou its 2005 Study Director of the Year award to recognize his significant contributions in organizing and leading the glucosamine analytical method collaborative study for the AOAC Official Methods program. The ceremony, at which AOAC President Dr. Henry Chin presented the award to Dr. Zhou, was held during AOAC's 119th Annual Meeting & Exposition in Orlando, Florida on Sept 11, 2005.

Dr. Zhou, who holds a Ph.D. in Physical/Analytical Chemistry from the University of Illinois, is Director of Lab Methods for NOW Foods. The glucosamine method for which Dr. Zhou was recognized was developed in NOW Foods' laboratories, which he heads. This method was evaluated by an Expert Review Panel, and then went through a Single Lab Validation. Finally, the glucosamine method was subjected to a collaborative study as part of AOAC's rigorous validation process required for its Official Methods.

Validated methods are significant in order to ensure product quality, and consumer safety and satisfaction.

Dr. Zhou was the AOAC Study Director for the collaborative study. This study involved 12 collaborating laboratories world-wide, 10 in the United States, one in Canada and one in Germany. The laboratories represented, respectively, dietary supplement finished product manufacturers, raw material vendors, commercial testing laboratories and university laboratories. Through the collaborative study, the glucosamine method met all the criteria for acceptance as an Official AOAC Method.
