Abstract

All crude oils and fats, obtained after rendering, crushing, or solvent extraction, inevitably contain variable amounts of nonacylglycerol constituents such as free fatty acids, sterols, tocopherols, hydrocarbons, pigments (gossypol, chlorophyls), vitamins, contaminants (pesticides, polycyclic aromatic hydrocarbons, etc.), heavy metals, glycolipids, and protein fragments as well as resinous and mucilaginous materials.

The objective of the refining process is to remove the unwanted constituents from the oil with the least possible negative effect on triacylglycerols and minimal loss of the desirable constituents. To be able to meet the ever-increasing quality requirements (mainly regarding the nutritional quality) and to further reduce the processing costs, equipment manufacturers are obliged to continuously improve their technology. Industrial deodorization technology and operating conditions have been adapted to meet the required organoleptic and nutritional quality standards.
