The main aim of edible oil refining is to make the oil suitable for human consumption. This involves making the oil flavorless, odorless, change in color, change in the crystal habit, rearrangement of their molecular structure and to make the extracted or mechanically pressed oil suitable as per our requirements. Another reason for the vegetable oil refining is to
One of the key steps in the refining process is the elimination of impurities from crude vegetable oils, especially the phosphatides or so-called gums. They need to be removed for two main reasons: they are responsible for high refining losses and they decompose, darken the oil due to their thermal instability. We Follow Different Routes For Different Oils: Low FFA
De-Waxing / Winterization Dewaxing or Winterization is a process to remove solids (saturated glycerides or waxes) from oil. These solids cause cloudiness in oil at low temperature. This process is suitable for oils like Sunflower Oil, Cottonseed Oil, Corn Oil, Ricebran Oil etc which have wax contents more than permissible limit. The oil is mixed with filter-aid and is cooled at desired
Deodorization Deodorization is the final stage of Oil refining. It removes odoriferous matter, free fatty acids and other unwanted components to produce bland and stable oil.
Bleaching Technology In addition to color pigments, Bleaching also removes residual phosphatides, metal contaminants, soaps and oxidation products. Oil undergoes Pre-treatment with Phosphoric acid/citric acid and the pre-treated oil is given a pre-determined retention before going to the Bleacher. This step splits soap and traps metal contaminants. The pre-treated oil is mixed with bleaching earth in inline
