The surfactant concentration, the electrolyte concentration, the detergent solution to tallow weight ratio and the crystal surface area affect the olein yield from the detergent fractionation of tallow. Three crystal sizes were produced by using various rates of cooling for the partial crystallization step. The amount of sodium dodecyl sulfate (SDS) needed to maximize olein yield was proportional to the surface area of the crystals. The olein yield of the separation increased with increasing detergent solution to tallow weight ratio and increased with increasing electrolyte concentration up to their optimum levels.
