## 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 โ23ยฐC. Mixtures of rapeseed and herring oi

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 Refined rapeseed oils with a high and a lowโerucicโacid content were fed to male Wistar rats for six months. Histomorphometric studies of the changes in predetermined heart sections indicated a significantly higher incidence and a greater severity of myocardial lesions in rats fed highโ
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

## Abstract The primary products of lipid oxidation are peroxides, which are usually quantified using iodometric methods, although interferent action and difficulty in determining the titration end point can lead to imprecise results. PeroxySafe^โข^ kits determine the peroxide value (PV) on the basi
