In Ghayabh/predictive-microbiology: bacterialgrowth Package

Description

The primary predictive model developped by Baranyi & Roberts in 1994, to predict microbial behavior in food environments.

Usage

modBaran(temp, mumax, lag, log10N0, log10Nmax)

Arguments

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

Details

\begin{equation}\log _{10}(N)=\log _{10}≤ft(N_{\max }\right)-\log _{10}≤ft(1+\frac{10^{\log _{10}≤ft(N_{\max }\right)-\log _{10}≤ft(N_{0}\right)}-1}{1-\exp ≤ft(-μ_{\max } \cdot \operatorname{lag}\right)+\exp ≤ft(-μ_{\max } \cdot(\operatorname{lag}-t)\right)}\right)\end{equation}

Value

log10N #a number

Examples

modBaran(temp=seq(0,24,0.5), mumax = 0.037, lag=4, log10N0 = 1, log10Nmax = 5 )
