## Abstract A column chromatographic method for determination of unsaponifiable matter (UM) in fats and oils has been developed. The procedure involves saponification of the oil and elution or UM through a mixed bed consisting of an upper layer of calcium oxide and a lower layer of basic aluminium
Several methods for the determination of TBA-value were compared with a new direct modification (omitting the previous distillation), using I-butanol as the sole solvent. The absorbance is measured at 530 nm after heating to 95 "C for 120 min, and cooling. The effect of variables was tested by the Y
