Abstract: A method for obtaining phospholipid concentrate from vegetable oils and a method for determining the size characteristics of the dispersed phase from phospholipid structures are proposed. It was found with light scattering and atomic force microscopy that the dispersed phase of the phospholipid suspension was formed by structures with linear particle sizes not exceeding 100 nm. The method of obtaining phospholipids in the nanosuspension form can be the basis for new technologies of phospholipid concentrates as sources of emulsifiers for the food industry, technological substance, as well as processing of oilseeds.

Keywords: spectrophotometry, atomic force microscopy, phospholipids, nanostructures, technological substances.
