Spreading pressure - water activity and moisture relationships in starchy materials
The spreading pressure values have been calculated by integration of the Gibbs equation using G.A.B. isotherm for different cereal grains and starchy materials. This procedure gives an useful analytic solution of the integral avoiding inherent mathematical instability at very low water activity. It...
