Abstract
In order to determine which sesame seed variety exhibited the optimal combination of geometrical features, this study compared three distinct varieties: one from sharzoor in Sulaymaniyah (S), another from Akre in Duhok (A), and a third from Mala Omar in Hawler (MO). The first portion of each sample was preserved in its original mixed form, while the subsequent portion was strained through a sieve using three distinct mesh sizes: 1.50, 1.35, and 1 mm. Less than an inch in diameter, medium in size, and tiny in diameter are the three resulting sesame seed sizes. The sesame seeds were measured in all three dimensions using a digital dial caliper. The volume (V, mm3), sphericity (S%), arithmetic diameter (Da, mm), geometric diameter (Dg, mm), apparent density (𝜌d, kg/m3), transverse surface area (At, mm2), and flat surface area (Af, mm2) were all measured for sesame seeds according to their geometrical features. The approximate weight of 100 seeds was also provided in grams. The results demonstrated that the sieved fraction was better than the mixed portion for each size category (mixed, big, medium, tiny). The geometrical parameters of Akre's sesame seeds were 3.33, 1.74, 0.89 mm, 3.31, 1.74, 0.91 mm, 3.08, 1.43, 0.88 mm, and 2.94, 1.24, 0.73 mm.
