The trans isomers present in fats and oils can be determined by the rapid liquid-film method from measurements of the infrared absorption at two wavelengths, one due to trans conformation of the double bond and the other due to ester group.
The ratio of the two absorbances has a linear relationship with the trans isomer content.
This method thus provides a simple determination of trans isomer without weighing in accuracy or messing up an exact volume.
