Adsorption kinetics and isotherms were investigated to develop a fundamental understanding of the adsorption mechanism. The adsorption rate …
WebSorption Isotherms are named as such because the equilibrium established must be for a constant temperature and this temperature should be specified. Normally, materials hold less moisture when they are hotter, and more moisture when they are colder. WebA moisture sorption isotherm equation is used to describe mathematically the rela-tionship between the activity (a w), and the equilibrium moisture content of a food product. ... The GAB equation is claimed to provide the best equation for the description of food isotherms up to a w 0.9 [18] and also adopted by the EEC-COST 90 Group on water
