AOAC SPSFAM Meeting Book 9-24

SMPR Key Points

 Extremely low levels of detection are desirable  Laboratory contamination and background levels of  BPA will be a challenge  Contamination can be found in all reagents and  water  Ensuring that test methods can be reproducible will  be an important challenge   Understanding different modes of detection for BPA  will be important

Comments Submitted

• 1. If the method is intended to measure free bisphenol A  only then it should be stated as such. The phenolic groups  of bisphenol A can react with beverage components (e.g.  acids) to form esters, which are not captured unless they  are first hydrolyzed. Response: Word “free” added to title • 2. The phrase "grain‐based dairy beverages" is sort of an  oxymoron. If the beverages are grain‐based they are not  dairy, even though their name contains the word "milk". Response:  Changed to “grain‐based beverages.”
