Processing

Edible Oil Processing

In the present context, the term edible oil processing covers the range of industrial processes that start with the isolation of triglyceride oils and fats from raw materials of biological origin. This range includes those refining processes that convert the crude oil into high quality oil products that are fit for human consumption and also the oil modification processes that ensure that the physical properties of the fats and oils meet market requirements at minimal cost. The production of oleochemicals and biodiesel are not considered in this section, nor are the disposal of by-products or waste products. The planned contents are -

Most authors contributing to the Processing sub-site of The Lipid Library work or have worked in industry. Their hands-on experience is reflected in their contributions. As with other sub-sites of The AOCS Lipid Library, the online nature of these contributions allows them to be conveniently updated to reflect advances in the field.
