Abstract
In this paper, the possibilities and effects of using domestic industrially produced zeolite for bleaching crudesunflower oil, compared to imported commercial bleaching earth, were examined.The parameters of the bleaching process in laboratory conditionswere: temperature 95°C, contact time 30 min,and mass fractionsof bleaching agent in oil: 0.2, 1, 2 and 3%.The following methods were used to characterize the bleachingagents: XRD, FTIR, BET and SEM/EDS.The bleaching efficiency parameters were determined by laboratory methods prescribed by the relevant ordinance on edible vegetable oils, and included: soap content, peroxide valueand fatty acid composition.The results of the research showed that the effects of bleaching sunflower oil with synthetic zeolite are similar to the effects of bleaching with imported commercial bleaching earth, with the former showing a slightly higher effectiveness in reducing the peroxide value.
KEYWORDS:sunflower oil; oil bleaching; synthetic zeolite; bleaching earth
期刊介绍：
Acta Technologica Agriculturae is an international scientific double-blind peer reviewed journal focused on agricultural engineering. The journal is multidisciplinary and publishes original research and review papers in engineering, agricultural and biological sciences, and materials science. Aims and Scope Areas of interest include but are not limited to: agricultural and biosystems engineering; machines and mechanization of agricultural production; information and electrical technologies; agro-product and food processing engineering; physical, chemical and biological changes in the soil caused by tillage and field traffic, soil working machinery and terramechanics; renewable energy sources and bioenergy; rural buildings; related issues from applied physics and chemistry, ecology, economy and energy.
