Abstract:
Water activities of sunflower seed (whole), hull and endosperm were measured at 25, 40 and 50°C and different moisture contents by means of an electronic aw‐meter in the range 0.199‐0.867. Based on the equilibrium between the water in air and a constant moisture specimen, the method permits a direct measurement of the isosteres and was used to estimate the variation of the isosteric heat with moisture content. In the range of temperature investigated it was found that the isosteric heat is pracitically independent of temperature. the hygroscopic equilibrium data of the different materials were modelled by a BET‐type two parameter isotherm for the whole range of water activity investigated.
