Dehulled sunflower seeds (Natura, Slovenia) were used for this research work.
The seeds were ground in a grinder (Bosch, Germany) prior to every experiment.
Material humidity was measured by a thermo-balance (Mettler-Toledo, Switzerland) and it was (3.68 ± 0.08)%. Total lipid content in seeds was determined by the AOAC official method 948.22 (Venkatachalam & Sathe, 2006) and it was (51.02 ± 1.95)%.
