## 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 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
## 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.
## Abstract A method for separating the methyl esters of erucic and cetoleic acids is described. Separation was achieved on silica gel plates impregnated with silver nitrate, utilising multiple development with a toluene: hexane mixture at a temperature of β23Β°C. Mixtures of rapeseed and herring oi
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
