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)%.
