Abstract Main improvements in the enzymaticultraviolet method for uric acid in flours include elimination of the uricase precipitation by trichloroacetic acid, which was not reproducible, and destruction of uricaselike material in flour before extraction. The method is capable of measuring as low as 3.2 mg uric acid per 100 g flour and is applicable to a variety of cereal products such as rice, rye, corn and soya flours, as well as barley, oats, etc.
