Determination method of dehydoroacetic acid has been newly devised. The outline of this method is as follows. On being allowed to stand at a room temperature for two days in 10% sodium hydroxide solution, dehydroacetic acid was hydrolyzed quantitatively into one mole of acetone, one mole of carbon dioxide and two moles of acetic acid. The acetone, recovered by distillation, was determined by the iodine method. The mechanism of alkali hydrolysis and effect of the other food additives on the method were examined.
