Capsules develop from the white or pink flowers, containing countless sesame seeds. The capsules dry out, making them burst. The seeds will scatter and considerable hand labour is required to safeguard the harvest. 

After being harvested the seed is cleaned and peeled if necessary. This process has usually been automated nowadays. In the initial stage of the cleaning process all kinds of irregularities are blown away by air. During the second stage the seed is washed and peeled. The latter is done in a large drum. Subsequently an electronic sorting machine will remove any discoloured seeds.
