What is the final step in the Physical refining of oil?

The final step in the physical refining of oils is deacidification and deodorization. Oils are deodorized under the conditions described above for chemical refining. The deodorization process has three main objectives:

Does refining affect the safety of refined oils?

These can directly influence the safety level of refined oils. Several studies were devoted to determining the effects of refining on the minor bioactive components such as sterols and tocopherols. Indeed, Verhé et al. [ 22 ], who found a sterols loss of 10¨C32% (physical refining) and 13¨C31% (chemical refining).

Why is degumming important in vegetable oil refining?

Degumming is a crucial step in the refining process of vegetable oils [ 9 ]. It allows the elimination of ¡°gums¡± or ¡°mucilage,¡± composed mainly of phospholipids from the crude oil as well as compounds such as carbohydrates, proteins, and trace of metals [ 9, 34 ]. Phospholipids or phosphatides are naturally present in oils.

What are the benefits of oil reprocessing?

Likewise, it allows obtaining oils that are more suitable for various industrial uses and getting rid of undesirable substances such as pesticide residues, metal traces, polycyclic aromatic hydrocarbons, dioxin, and alteration products as well as minimizing oil loss during processing ( Table 1) [ 11 ].
