Phytosterols (PS) are similar to cholesterol both in structure (but have different side chain configurations) and in function (Fernandes & Cabral, 2007).PS exist in free or esterified forms: free sterols form part of the cellular wall, where they play important structural functions, whereas sterol esters represent storage products within the cell.

Fatty acid steryl esters (FASEs) are conjugated phytosterols, in which the OH group of free phytosterols is ester-linked with a fatty acid, such as palmitate and stearate sitosteryl esters as shown in Fig. 1.They have gained much attention in recent years as nutraceuticals for their blood cholesterol lowering efficacy (Moreau, 2004, Ostlund, 2002, Piironen et al., 2000).

Phytosterols have been recovered from the deodorizer distillate produced in the final deodorization step of vegetable oil refining by various processes. The deodorizer distillate contains mainly free fatty acids (FFAs), phytosterols, and tocopherols. The presence of FFAs hinders recovery of phytosterols.
