Abstract
The hydration behaviour of sorghum [Sorghum bicolor (Linn.) Moench] grains using traditional and modified soaking techniques was investigated. Three sorghum varieties (SAMSORG-14, SAMSORG-41 and SAMSORG-42) were used for the study; three traditional soaking techniques (SWG-72, PBW-24 and IBG5-24) were involved; while the equilibrium moisture content (EMC) for each variety was obtained experimentally. The hydration behaviour of sorghum grains was found to be influenced by variety, soaking method and time. The Peleg’s model for predicting water absorption behaviour of grains was not appropriate for the traditional/modified soaking methods due to the non-constant nature of temperature of soaking. The Peleg’s model was not accurate when used to predict the EMC of the traditionally-soaked sorghum grains. Generalized equations were derived for each traditional/modified soaking method with respect to individual sorghum variety. These equations would be of great relevance in the prediction of total moisture content in the grains at any time of soaking but the assumption is that such soaking duration must be less or equal to the time for EMC attainment with respect to the variety involved.
