摘要：

Moisture sorption isotherms were determined for defatted canola meal at 16, 22, and 34 degrees C. The isotherms were fitted to the Guggenheim-Anderson-deBoer (GAB) sorption equation. This equation was then used to develop a packaging model that predicted the changes of moisture content of canola meal under stated environmental and packaging conditions. The model was tested using Melinex 813 (12 mu m) and Propafilm C (28 mu m) packaging films at 86% relative humidity and 23 degrees C. The GAB equation provided a good fit to experimental data (< 3% RMS). The monolayer moisture content of the meal was 9.5%. The enthalpy of sorption of the monolayer at 22 degrees C was 84.61 KJ/mol. The model predicted the time required by packaged canola to attain a selected moisture content +/- 0.5 days.
