Sunflower Oil Production Process
The journey of transforming raw sunflower seeds into drops of golden, fragrant, and transparent oil is an elaborate process combining the essence of nature and modern technology.
Harvesting Sunflowers
Sunflower harvesting typically occurs in late summer to early fall, depending on the region and cultivar. In large sunflower fields, harvesting is done by specialized machines that save time and effort.
Processing Sunflower Seeds
Once harvested, the sunflower seeds are quickly transported to the factory to begin processing. The process includes:
- Thorough cleaning to remove dirt, impurities, and mixed shells
- Shelling to remove the hard outer shell and get to the ivory white kernel
- Screening to completely remove the shell and remaining impurities
- Gentle heating to increase extraction efficiency while preserving flavor and nutritional value
- Pressing to slowly squeeze out each drop of golden oil
Quality Control and Packaging
The oil is analyzed in the laboratory and undergoes sensory testing to ensure it meets safety and quality standards. If it meets the standards, the oil is transferred to the next refining step or packaged as a finished product.
Distribution and Consumption
The packaged oil is stored in suitable conditions to ensure product quality and then distributed to agents, supermarkets, and stores nationwide, ready to reach consumers. The golden drops of oil retain the natural flavor and are rich in nutrients, providing a healthy and safe source of energy for every family’s daily meals.
