WeibullMafart_iso {bioinactivation}

Isothermal Weibull-Mafart Model

Description

Returns the predicted logarithmic reduction in microbial count according to Weibull-Mafarts's model for the time, temperature and model parameters given.

Usage

WeibullMafart_iso(time, temp, delta_ref, z, p, temp_ref)

Arguments

time

numeric indicating the time at which the prediction is taken.

temp

numeric indicating the temperature of the treatment.

delta_ref

numeric defining the delta-value at the reference temperature.

z

numeric defining the z-value.

p

numeric defining shape factor of the Weibull distribution.

temp_ref

numeric indicating the reference temperature.

Value

A numeric with the predicted logarithmic reduction (log10(N/N0)).
