Comparison of steam and nitrogen in the physical
Deacidification in physical refining is one of the most sensitive steps in refining edible vegetable oils because of its large impact on the quality of the oil. The removal of volatile compounds such as FFA is accomplished at elevated temperatures and a high vacuum with a stripping gas, usually steam. The aim of this work was to verify, at the laboratory level, the advantages of using an

Comparative performance of steam and nitrogen as
The amount of nitrogen needed was much lower than that of steam for refined oils of similar high quality. The results also suggested that the amount of stripping gas had a clear influence on the composition of deodorizer distillates because lower quantities of triglycerides and unsaponifiable matter were found when nitrogen was employed.
Another is the increased use of physical refining because of consumer pressure for less "chemical" processing. Conclusions. Rural refining of oil-bearing plants can produce fats and oils of good quality which provide needed energy and fat soluble vitamins. Commercial refining produces fats and oils that can be of high quality and have the

Chemical Refining and Physical Refining of Vegetable Oil
Physical Refining. Apart from chemical refining, physical refining is another method that used for edible oil refining. Through this method, the free fatty acids are removed during the process of distillation, which is one stage of deodorizing. The crude oil should be thoroughly degummed to come up with effective results. This is not applicable

Physical refining, also known as deacidification by steam distillation, is a process in which free fatty acids and other volatile compounds are distilled off from the oil, using an effective stripping agent (usually steam) and suitable processing conditions.
