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
Standard methods for the determination of iodine values of oils involve direct addition of halogen elements to the double bond. Since the reaction proceeds slowly there is a risk of substitution. A direct coulometrical titration method has been investigated.

## Abstract Variations in the proportions and iodine values of fats at different locations in the endosperm or embryo were studied for several different types of seed. The variations in oil content and iodine value occur in systematic patterns with reference to the centre of the seed or in some ca
## 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^™^ kits determine the peroxide value (PV) on the basi
The use of infrared spectroscopy in the study of fats and oils is reviewed. The importance of the mid-infrared region in the study of lipids is shown. Di †erences between dispersive and Fourier-transform infrared techniques are commented on and the experimental methods used in the handling of oil an
## 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
