Vegetable Oil Deodorizer Distillate: Characterization, Utilization and Analysis

Depending on the sources, deodorizer distillates usually have significantly different characteristics, uses, and value. Soybean oil deodorizer distillate has been suggested as an alternative to marine animals as natural source of squalene and as a good raw material for the production of fatty acid steryl esters, tocopherols, free phytosterols and fatty acids. The aim of this review paper is to discuss the characteristics, uses, and value of vegetable oil deodorizer distillate (VODD), isolation and separation techniques of bioactive compounds from VODD, and analysis of VODD, as well as their future perspectives. The development of new separation techniques for isolating bioactive compounds and methods of analysis are highlighted and discussed.
