A unique sesame oil, rich in natural antioxidants, is the result of a successful collaboration between researchers from the Faculty of Chemistry at the University of Łódź and the Polish company Olini. The final product contains a high concentration of sesamol—a potent antioxidant. Thanks to production process modifications, the oil is now significantly more resistant to oxidation.
According to Professor Rafał Głowacki, Dean of the Faculty of Chemistry, the partnership between the Department of Inorganic and Analytical Chemistry and the family-owned company Olini has been ongoing for several years. In this latest stage, researchers focused on measuring sesamol content in oil samples produced using different technological variants.
“This collaboration has led to the development of an improved version of sesame oil. Together, we discovered a method to extract a significantly higher amount of sesamol—a powerful antioxidant—from sesame seeds. Through a series of experiments, and with the input of experts from the Faculty of Chemistry, we optimized the roasting method, including its time and temperature, which allowed us to enhance our product,” said Łukasz Bogdański from Olini.
Researchers from the University of Łódź emphasize that the resulting oil stands out due to its high oxidative stability, which translates into longer shelf life—even under high-temperature conditions. In addition to sesamol, the oil is rich in unsaturated fatty acids, primarily oleic and linoleic acids, which help maintain healthy lipid metabolism and support a favorable cholesterol profile.
Thanks to its content of sesamol, sesamin, and sesamolin, the oil exhibits strong antioxidant properties, helping to neutralize free radicals and protect cells against oxidative stress.
Professor Głowacki highlights that the joint effort to develop an oil rich in biologically active compounds is a prime example of how scientific expertise and practical application can be successfully combined. The sesamol content in the final product has been verified by the University of Łódź’s laboratory, allowing the university’s logo to appear on the product packaging.
