Abstract

The viscosities of olive oil and its constituent fatty acids were measured using a falling sinker-type high-pressure viscometer. The viscometer consists of a titanium cylindrical sinker with ferrite core and descends concentrically under the influence of gravity through a close-fitting titanium tube. The movement of the sinker was detected by electrical induction through coils surrounding the tube. For the oil and fatty acids, the calculated dynamic viscosity increased according to the model η=ηo exp (β p). The coefficients were readily obtained by linearizing experimental data for sinker fall-times and found to be dependent on the chain length and degree of saturation.
