To obtain oil, watermelon seeds are sun dried. This lowers the water content in them. Then the seeds are pressed for extracting fine, yellow colored oil. There are many ways in which this oil is extracted.
• Cold pressed method
• Solvent extraction using hexane as solvent.
• Supercritical carbon dioxide extraction.
Among these, cold pressed oil is the healthiest as it does not contain any artificial ingredient. It is pure, natural and organic watermelon seed oil.
