Popis: A model describing the hygroscopic properties of hydrophilic biological polymers is suggested. The quasi-chemical approach was used to obtain an equation for the sorption of water vapor in them. An analysis of experimental data showed that this equation correctly described the hygroscopic properties of the main biopolymers of cereal grains, starch and protein, over a wide range of humidity values. The equation also well described the hygroscopic properties of many cereal grains. The nonlinear regression method was applied to obtain the main parameters of absorption isotherms for grains of certain crops.
