Abstract

50 kg batches of cleaned sesame seed (SS) were boiled for 1 min with 80 l. of 0.6% NaOH solution, cooled with an equal vol. of cold water and dehulled in a fruit pulper having a sieve with 1/16 in perforation. After washing and destoning, the SS was dried and pressed, and the resulting cake extracted with hexane. 50 kg of black SS yielded 42 kg of dehulled seed, from which 25 kg of oil and 17 kg of sesame flour (SF) were prepared; losses of oil and protein were 1.2% and 3.5% respectively. Tables are given of the moisture, fat, protein, ash, crude fibre, oxalic acid and Ca contents of black and dehulled SS, and of expeller pressed and solvent extracted SF. Samples of dehulled SS and solvent extracted SF were stored for 6 months at O'C, room temp. or 37 degree C, and the peroxide value and free fatty acid content determined at monthly intervals; no appreciable increase was observed. Organoleptic properties of all samples were acceptable after 6 months. Ecconomics of the process are discussed.
