Polymorphic behavior during isothermal crystallization of high stearic high oleic sunflower oil stearins

► High stearic high oleic sunflower oil crystallized in five polymorphic forms ► α, β'2 and β'1 were obtained after direct cooling ► β forms were obtained at longer times during storage ► Stearins fractionated and solid solutions crystallized in different polymorphs ► Polymorphic behavior was influenced by interactions among triacylglycerols.
