Abstract

Starch was extracted from two varieties of sorghum bicolor grains (white and red varieties) steeped for 6, 8 and 12 hours by wet milling method, the starch samples were analyzed for yield, functional properties and overall acceptability. The yield of the white variety ranged from 0.45 – 0.70kg and the red variety was 0.40 – 0.50kg. The result of their functional properties were as follows; Bulk density, white (0.700 – 0.733g/ml), red (0.723 – 0.753g/ml) Gelation temperature; white (70 – 72oc) red (73 – 74oc). Least gelation concentration; white (0.60 – 0.90g/10ml), red (0.70 – 1.00g/10ml). Metabolisable energy value, white (3.12 –3.82kcal/g), red (3.73 – 3.82 kcal.g). Glycosidic cyanide content, white (4.5 – 8.5%), red (8.5 – 10.5%). The starchy samples with shorter steeping periods gave better results in terms of functional properties, metabolisable energy value, and percentage moisture content. The starch samples steeped for longer periods had greater yield but poorer functional properties. The white variety tested cyanide free and had better results than the red variety. The result of the sensory evaluation revealed that the samples had significant difference at p(0.05) and p(0.01) in colour and consistency. But there was no significant difference at p(0.05) and p(0.01) in flavour, texture and overall acceptability
