Physical Refining
In Physical Refining, Vegetable Oil is subject to distillation to remove free fatty acids. The alkali treatment is completely avoided. This reduces the amount of waste water and eliminates production of soap. This process is becoming more popular.

Degumming
The purpose of Degumming Vegetable Oils is to remove GuLD. All oils have hydratable and

non-hydratable guLD.
a. Water Degumming: Hydratable guLD are removed by treating oils with water and separating the guLD. The guLD can be dried to produce lecithin.
b. Acid Degumming: Non-Hydratable guLD are removed by treating oils with acids and separating the guLD.

Neutralizing
The purpose of Neutralizing Vegetable Oils is to remove Free-Fatty Acids (FFAs). Traditionally, FFAs are treated with caustic soda (NaOH). The reaction produces Soaps which are separated from the oil. Because trace amounts of soaps remain in the oil, the oil is either washed with water or treated with Silica.

Some processors prefer not to perform caustic neutralizing. Instead, they prefer Physical Refining in which the FFAs are evaporated from the oil under high temperature and vacuum. This process can be combined with deodorization step described under FFAs stripping.

Physical Refining process is preferred because (a) it does not produce soaps; (b) it recovers fatty acids that provide better cost recovery; (c) there is smaller yield loss compared to caustic refining—especially for oils with higher FFAs; and (d) it is a chemical-free process.

Bleaching
The purpose of Bleaching is to remove color pigments contained in Vegetable Oils. The oil is treated with Bleaching Clays that LDorb the color pigments. The clay is filtered and the clean bleached oil is stored for further processing. Process flow diagram is attached.

Deodorizing
The purpose of Deodorizing Vegetable Oils is to remove odor substances. The oil is subjected to steam distillation under high temperature and vacuum to evaporate all odor substances. The resulting deodorized oil is almost bland and tasteless.
