Summary A method for the determination of the methoxyl content of fats has been developed using chromotropic acid. The fat is saponified and the methanol recovered by distillation, oxidized, and reacted with chromotropic acid. The optical density of the colored solution at 5,700 A is proportional to the methoxyl present.
