sci.maillard-browning-kinetics Calculator
Calculates Maillard browning reaction rate from temperature and water activity, using an Arrhenius model with suppression at aw > 0.8. Maillard reaction rate peaks at aw = 0.6–0.7 — at higher aw, dilution of reactants slows browning; below 0.2, mobility limitation reduces it.
Inputs
T C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Aw
Reference formula or conversion factor shown for context.
Ph
Reference formula or conversion factor shown for context.
Results
effective rate constant k_eff (relative)
The value at the specified point or condition.
temperature factor k_T (relative)
A dimensionless multiplier applied in the calculation.
aw factor
A dimensionless multiplier applied in the calculation.
pH factor (alkaline accelerates)
A dimensionless multiplier applied in the calculation.
