Description

This is the primary predictive model developped by Baranyi & Roberts in 1994, to predict microbial behavior in food environments.The model modBaran_without_lag has four parameters (temps, mumax, log10N0, log10Nmax) without lag phase.

Usage

modBaran_without_lag(temp, mumax, log10N0, log10Nmax)

Arguments

temp	time(h)
mumax	maximum growth rate # a number
log10N0	Initial population density #a number
log10Nmax	maximum population density # a number

Details

\begin{equation}\begin{array}{l} \mathrm{LOG} 10 \mathrm{N}=≤ft(\mathrm{LOG} 10 \mathrm{Nmax}-\log 10≤ft(1+≤ft(10_{\mathrm{m}}^{\wedge}(\mathrm{LOG} 10 \mathrm{Nmax}-\mathrm{LOG} 10 \mathrm{N} 0)-1\right)\right.\right. \\ ≤ft.≤ft.* \exp ≤ft(-\operatorname{mumax}^{*} \mathrm{t}\right)\right)\right) \end{array}\end{equation}

Value

log10N #a number

Examples

modBaran_without_lag(seq(0,24,1), 0.5,3,5)
