IWAI SESAME OIL Co.,Ltd
DIRECTOR

We have been in business for more than 170 years. We have been pressing sesame oils slowly and carefully using traditional techniques and sparing no effort.
Through sesame seeds and sesame oil, we contribute to the improvement of food culture by providing “food safety and security ” and “ healthy, tasty, high-quality products,” and continue to make daily efforts for local communities, business partners, consumers, shareholders, and employees.

Special Making

Heating and Roasting

To bring out the distinctive flavor and fragrance of Iwai sesame oil, we heat and roast our sesame seeds using traditional techniques. Our experienced roasters use all five senses to assess everything from the condition of the seeds to the temperature and humidity of the air that day, fine-tuning the process to give the finished oil its one and only character.

Extraction

We extract oil from fine roasted sesame seeds using traditional pressing techniques, never using chemical solvents. Our equipment and facilities have evolved over the years, but our basic methods remain unchanged from 170 years ago, preserving the rich flavor and fragrance our oil is known for.

Filtration and Settling

After extraction, our oil is strained and transferred to tanks where it sits for two weeks, allowing the sediment to settle. Centrifuges might be more efficient, but allowing sediment to settle over time better preserves the flavor and fragrance. We then perform a final filtration process using cartridge filters that give our sesame oil a translucent amber finish.
