PUPMSI (version 0.1.0)

Lewicki3MSI: Lewicki-3-Parameter Moisture Sorption Isotherm

Description

The three-parameter Lewicki model is most suitable for describing the sorption characteristics of raw potato, potato starch, starch-sugar and starch-salt gels within specific temperature and water activity ranges.

Usage

Lewicki3MSI(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 Lewicki-3-Parameter model.
