Bilous O. Technology of plant oils stabilization by complex antioxidant

Research object - technology of stabilization vegetable oils to oxidative deterioration by the complex antioxidant. The aim - to improve a technology of stabilizing vegetable oils to oxidative deterioration by developing and by injecting of complex plant antioxidant consist of walnut leaves and flowers of calendula extracts. Methods: fatty acid composition of the oil defined by gas-liquid chromatography; the content of inhibitors defined by Volumetric method; induction periods measured on the device Oksytest; for planning experiments, data processing, approximating modeling, used MathCad and Microsoft Exel software packages. Theoretical and practical results: the technology of stabilizing vegetable oils by the complex antioxidant extracts from leaves of walnut and calendula flowers, which guarantees the extension of the shelf life period of vegetable oils more than twice. Received a patent оf Ukraine on utility model for the way of inhibition of oxidative damage to fats, oils and fat-containing products. Scientific novelty: for the first time found that the degree of unsaturation of fatty acids, the oil consist of, does not affect the antioxidant activity of the antioxidant invented; for the first time have developed a method of introducing an antioxidant, which is a water-alcohol extract of plants to oil; the dependence between technological parameters of mentioned antioxidants extraction process and the rate of oxidation of sunflower oil have defined; as a numerical approximation models have defined the dependence between induction period of forced sunflower oil oxidation and ratio of herbal antioxidants, including the conditions of their joint introduction; have extended the knowledge base about the basic laws of interaction kinetics of peroxide radicals sunflower oil with oxidation inhibitors contained in the complex antioxidants. Level of implementation: results confirmed by Ukrainian Research Institute oils and fats (m. Kharkiv) and used in the educational process NTU "KPI". Scope: oil and fat industry.
