Desorption isotherms of shelled maize: whole, dehulled and hulls
Water vapour desorption isotherms of whole kernel maize were determined at 40, 50 and 60°C, and those of dehulled kernels and hulls at 50 and 60°C. It was found that while whole and dehulled kernels show similar equilibrium moisture contents, the hull gives lower values. Equilibrium data were modell...

| 520 | 3 | |a Water vapour desorption isotherms of whole kernel maize were determined at 40, 50 and 60°C, and those of dehulled kernels and hulls at 50 and 60°C. It was found that while whole and dehulled kernels show similar equilibrium moisture contents, the hull gives lower values. Equilibrium data were modelled with two‐parameter equations. It was found that the Henderson equation is best for describing the equilibrium data for whole kernels, while the Halsey equation was more appropriate for hulls. A simple semi‐theoretical equation was used to model the effect of temperature on the equilibrium values of whole maize kernels for the three temperatures investigated. BET heats of desorption and the isosteric heat curves were calculated for whole kernels and hull. It was found that the BET heat values correlate quite well with the isosteric heat values at the monolayer moisture content. Copyright © 1990, Wiley Blackwell. All rights reserved |l eng | |
