Pretreatment of Sunflower Seeds

Sunflower seed oil extraction process generally begins with cleaning. Magnetic selector is used in order to remove any trace metal, and the seeds are scrubbed of any foreign matter. If the moisture content of the seeds is too high it will have an adverse effect on the quality of final sunflower oil produced, so drying is needed. Then, the seeds are cracked by a pneumatic or centrifugal sheller / dehuller, and the result is winnowed to separate kernel from hull.

Sunflower Oil Refineing Section

Once it has been squeezed through the slots, it can be collected and refined in oil refinery plant. This involves heating the oil to between 40℃ and 85℃ and mixing it with an alkaline substance such as sodium hydroxide or sodium carbonate. Together with this additive, the undesired fatty acids form a soapy substance that is then removed using centrifugal force. The oil is cleaned to remove any traces and dried. It is then degummed, the oil treated with acidic water or steam to remove hosphatides. Once again, centrifugal force is used to remove any dregs.

Oil that will be used for cooking is then bleached by filtering it through activated clay or fuller’s earth, substances which can absorb pigmented materials from the oil. Oils that will be refrigerated are filtered to remove waxes. The final step is deodorising the oil. The oil is placed in a vacuum at 225℃ to 250℃, over which steam is passed to distill any odor or volatile components. A tiny amount of citric acid might also be added to increase the oil's shelf life. Once this is complete, the finished oil can be packed and shipped to shelves across the world.
