PelegMSI: Peleg Moisture Sorption Isotherm

Description

Peleg model is an empirical 4-parameter isotherm which describes sigmoidal and non-sigmoidal behavior of isotherm plots.

Usage

PelegMSI(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 Peleg Moisture Sorption Isotherm model.
