The accurate quantification of gluten is a crucial factor when labeling gluten-free and/or gluten-reduced beer. Currently, there is no federally-recognized analytical gluten quantification method, making compliance complicated at best. The linchpin for gluten regulations, and the adherence thereof, is a robust and valid gluten detection and quantification method. The ASBC, along with various other scientific societies, have performed independent studies validating the R5 Competitive ELISA Gluten Method in beer and have recognized this method as repeatable and reproducible for the quantification of gluten in beers consisting of varying grist material. In an effort to avoid labeling discrepancies and ensure the health of the public, numerous analytical techniques are being explored for their validity in hydrolyzed food products. Advancements in these methods, along with an overview of the current methodology and considerations for implementation and interpretation, will be discussed.
