Optimization of the detergent fractionation of tallow to maximize olein yield depends on selecting the correct detergency and rheological properties of the aqueous dispersion. The efficiency of the separation is related to the apparent viscosity of the mixture. The apparent viscosity of the dispersion as determined in a paddle mixer viscometer decreased from .3 Pa‐s to .1 Pa‐s as the olein yield increased from 66% to 79%.
