Hestia Inter, Brussels, Belgium, responds to a reader from Niger who asks, 'Could you advise us regarding decorticating sesame?' SPORE: 'The hay seeds of sesame are rich in oil, proteins, calcium and phosphorus. Their use is inhibited by a cuticle containing pigments, which must be removed by a decorticator. Many methods have been studied, all have an initial stage where the seeds are soaked before being dried through a series of vibrating sieves. Decorticating can be done mechanically, with a disc decorticator. The mix of cuticle and decorticated seed are then passed through a metal sieve under a strong current of water. They must then be air-dried before being sieved again in order to obtain the clean seed. Chemical decorticating is done by soaking the washed seed in a 0.6% solution of soda which is brought to the boil to remove the cuticle. Thorough washing in plenty of water is then essential, followed by sieving in order to remove the cuticle arid then drying as in the mechanical process. These are methods which are suitable for use on a small scale at artisanal level. ' For more information, please contact CTAs Question Answer Service
