Crushing: The cleaned sunflower seeds are crushed to obtain a crude oil mixture.
Extraction: The crude oil mixture is then subjected to a solvent extraction process to separate the oil from the seed residues. The most commonly used solvent in sunflower oil production is hexane.
Degumming: The extracted oil is then subjected to a degumming process to remove any impurities and unwanted substances, such as phospholipids.
Neutralization: The degummed oil is then neutralized with an alkali solution to remove any free fatty acids present in the oil.
Bleaching: The neutralized oil is then bleached to remove any remaining impurities and unwanted substances, such as pigments and odors.
Deodorization: The bleached oil is then deodorized to remove any remaining odors and flavors.
Refining: The deodorized oil is then refined to improve its quality and stability. This can involve processes such as winterization, which removes any waxes, and dewaxing, which removes any remaining impurities. ... 29
