Fluorometric Method for Determination of Uric Acid in Flour
Abstract
A fluorescence technique is described for the determination of uric acid content in flour and its use as an index of insect infestation. Uric acid, a major component of the excreta of adult Tribolium used in this study for natural infestation, accumulates in infested products providing a quantitative measure of past plus present degree of infestation. The efficiency of uric acid extraction from flour with 0.2 M sodium acetate, checked by adding known amounts of uric acid to flour, is shown to be about 96-98% accurate. The method is capable of detection of uric acid at the level of 3.0 mg per 100 g of flour.
