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 machinery is used to refine palm oil?
Hence, here is a table showing machinery used to refine palm oil: A neutralizer works to reduce the free fatty acid (FFA) content in crude palm oil (CPO), improving its quality for various applications. This is achieved through a chemical reaction with an alkaline solution.
What is refining in edible oil processing?
Refining is the last step in edible oil processing. We are committed to making every drop of oil safe, healthy and nutritious. Value-adding by-products may be produced from processing stages like Degumming, Neutralization, Bleaching, Dewaxing/Winterization and Deodorization.
How are vegetable oils obtained?
Vegetable oils are obtained by mechanical expelling or solvent extraction of oleaginous seeds (soybeans, rapeseed, sunflower, etc.) or oleaginous fruit like palm and olive [ 2 ].
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.
How is crude palm oil refined?
The refining of Crude Palm Oil (CPO) involves several essential stages to transform it into a refined and market-ready product. Here’s an overview of these stages: The first stage focuses on reducing the free fatty acid (FFA) content in CPO.
