Iglesias-Chirife Moisture Sorption Isotherm
Description
Iglesias-Chirife Isotherm is an an empirical equation for describing water sorption behavior of various fruits and other sugar-rich foods.
Usage
IgleChiMSI(WaterAct, AdsorpM, DesorpM)
Arguments
WaterAct |
the numerical value of Water Activity, which ranges from 0 to 1. |
AdsorpM |
the numerical value of the Moisture content of the Adsorption curve, which ranges from 0 to 1. |
DesorpM |
the numerical value of the Moisture content of the Desorption curve, which ranges from 0 to 1. |
Value
the nonlinear regression, parameters, and graphical visualization for the Iglesias-Chirife Moisture Sorption Isotherm model.
