What is a Physical refining process?

In general, physical refining includes the following three main processing steps: Sometimes the dewaxing process is added for types of oils rich in waxes (e.g., fatty acids with low solubility in oils and high-melting esters of fatty alcohols), such as corn, rice bran, canola, and sunflower oils [ 29 ].

What is chemical refining?

Chemical refining is the traditional method used since ancient times. It can be used for all fats and oils even when they have been slightly degraded. Each step of the refining process has specific functions for removing some undesirable compounds. Chemical refining follows six processes:

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:

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.
