Work out shelf life from temperature (q10) instantly with clear inputs, formula shown and shareable results.
The Q10 model says deterioration rate multiplies by Q10 for every 10 degrees of temperature rise, so shelf life divides by Q10^(deltaT/10). Chilled foods commonly show Q10 between 2 and 4, so a break to 10 C from 4 C can cut remaining life by half or more.
Q10 shelf life
Adjusted shelf life = baseline shelf life / Q10^((T_actual - T_baseline) / 10)
Shelf life must be established by validated challenge and storage studies. Q10 extrapolation is for cold chain assessment, not for setting a use-by date.
Yes. Each period at each temperature consumes a fraction of total life, and those fractions add. That is the principle behind time-temperature indicators on chilled packs.
Approximately, over a limited range, but microbial growth has a minimum temperature below which it stops entirely and an optimum above which it slows. Predictive microbiology models are more reliable near those bounds.
