## Abstract A method has been developed for the quantitative measurement of erucic acid in complex samples of oils or fats containing marine oils and/or hydrogenated fats. A two step procedure is proposed: in a first step the constituent fatty acids of the transesterified oil or fat are resolved on

## Abstract In view of requirements set in 1979 by the European Community regarding the reduction of erucic acid levels in foods, we developed a method by which concentrations down to 0.1% can be determined. The procedure and conclusions are discussed in brief.
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
