food.food-spoilage-shelf-life Calculator
Estimates remaining shelf life of a stored food product from initial quality, current quality, and storage temperature using the Q10 temperature coefficient. Every 10°C rise in temperature roughly halves shelf life for most perishable products.
Inputs
Initial Microbial Count Log
Reference formula or conversion factor shown for context.
Max Acceptable Log
Reference formula or conversion factor shown for context.
Growth Rate Per Day
Annual percentage increase. Enter as a percentage. Compound growth is exponential — small differences in rate become enormous over long periods.
Lag Phase Days
Reference formula or conversion factor shown for context.
Results
shelf life estimate (days)
The value at the specified point or condition.
lag phase (days)
The current phase of the cycle or process.
exponential growth phase (days)
The absolute increase in value over the period. Growth = final value minus initial value.
total log increase
The combined total across all inputs and components.
shelf_life = lag + (N_max-N_0)/k
Sample size or count used in the calculation.
Q10 rule
Reference formula or conversion factor shown for context.
