Polyhydroxylated fullerene influence on the oxidation stability of camelina oil during storage

The purpose of research is to study the effect of polyhydroxylated fullerene (fullerenol [C60(OH)24-26]) on the oxidative stability of camelina oil during storage. Objectives: to determine the effect of fullerenol on the organoleptic and spoilage indicators (acid and peroxide values) of camelina oil during storage. The study was carried out in the laboratory of the Institute of Applied Biotechnology and Veterinary Medicine and in the State Regional Center for Standardization, Metrology and Testing in the Krasnoyarsk Region, the Republic of Khakassia and the Republic of Tuva. The object of the study was natural unrefined camelina oil produced by cold pressing (oil grade P), manufactured by Eley LLC in accordance with GOST R 59148-2020 and TR TS 024/2011 (Novosibirsk), widely represented in the retail network of Krasnoyarsk. In the process of work, studies were carried out on organoleptic indicators and indicators of spoilage (acid and peroxide numbers) at the beginning of storage and at the end of storage (12 months) of the oil. Organoleptic indicators and indicators of oxidative deterioration of natural unrefined camelina oil produced by cold pressing, at the beginning of storage without an antioxidant, complied with the requirements of regulatory documents enacted on the territory of the Russian Federation. The use of fullerenol 0.004 % (test sample I) and 0.008 % (test sample II) by weight of oil compared to the control sample at the end of storage (12 months) does not affect the organoleptic characteristics of the studied oil samples, reduces the peroxide value by 1.9, respectively and 2.9 meq/g and acid number by 0.05 and 0.07 KOH/g, respectively. The results obtained show the antioxidant capacity of fullerenol in small doses.
