摘要：

The appropriate pretreatment of crude oil is of crucial significance for the application of physical refining. This paper presents a simplified process for the preparation of sunflowerseed oil by applying multistep acid degumming as the only pretreatment step. Amorphous silica hydrogel was used instead of treatment with bleaching earth. The results obtained showed that samples of crude-pressed and extracted sunflowerseed oil differ significantly with respect to the content and composition of phosphatides, which is important for the pretreatment. The proper choice of oil and the application of multistep acid degumming results in an effective pretreatment of sunflowerseed oil for physical refining.
