Abstract
A simple microdiffusion procedure is described for the determination of acetaldehyde in beer, whereby the acetaldehyde content of the beer sample in the outer chamber of a Conway unit is absorbed in a semicarbazide solution and the optical density of the product is measured at 224 mμ. The estimation is not specific for acetaldehyde, as it in fact determines total volatile carbonyl compounds. A colorimetric estimation is also described.Keywords
