Sesame seeds (or sesamum or benniseed) are the seeds of the tropical annual Sesamum indicum. The species has a long history of cultivation, mostly for its yield of oil. Nigeria is a leading producer of sesame seed in the world with an annual production of about 120,000 tons and as such sourcing the raw materials would not be a challenge.
Sesame can be processed to several different stages, such as simple cleaning, or cleaning and dehulling, cleaning/dehulling/drying, cleaning/dehulling/drying/crushing for oil, etc. In Nigeria, the primary processing facilities focus almost exclusively on cleaning. There are a few commercial cleaning facilities, and they are all privately held. Two are in Kano with a cleaning capacity of about 100 tonnes a day, and one is in Lagos with a cleaning capacity also of about 100 tonnes a day.
