Which industrial technologies are used for vegetable oils’ refining?
The present review aimed at comparing the two main industrial technologies used for vegetable oils¡¯ refining, namely, chemical refining and physical refining. Chemical refining removes free fatty acids by soda neutralization.
What is conventional deodorization for refining vegetable oil?
Conventional deodorization for refining vegetable oil involves evaporating volatile molecules by applying high temperatures (240¨C260 °C) for 2¨C3 h. It inevitably leads to a degradation of the refined oil quality. The chief volatile compounds from the conventional deodorization process were hydrocarbons, which are not the odor source of the oil.
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.
Is solvent extraction a new method for deacidification of vegetable oils?
Rodrigues et al. ( 2007) had thoroughly reviewed the different studies carried out on the use of solvent extraction as a deacidification technique for various type of vegetable oils. Despite these studies, solvent extraction is still considered as a new approach in deacidification of vegetable oils.
