sci.water-activity-BET-monolayer Calculator
Calculates BET monolayer moisture content m₀ and BET constant c from sorption isotherm data at multiple water activities. BET linear plot: aw/(m(1−aw)) vs aw — slope = (c−1)/(m₀c), intercept = 1/(m₀c); m₀ and c fully characterise the BET model.
Inputs
Aw
Reference formula or conversion factor shown for context.
M Content G 100G
Reference formula or conversion factor shown for context.
C Bet
Reference formula or conversion factor shown for context.
Results
BET monolayer moisture m0 (g/100g)
Sample size or count used in the calculation.
BET linearity check Y
A pass/fail verification against the applicable code, standard, or threshold.
water activity aw
Water activity (aw) — the ratio of vapour pressure to pure water at the same temperature. Above 0.85: microbiological growth risk. Below 0.6: most microbes cannot grow.
moisture content m (g/100g)
Sample size or count used in the calculation.
BET isotherm: aw/((1−aw)m) = 1/(m0·C) + (C−1)·aw/(m0·C)
Reference formula or conversion factor shown for context.
food stability guidance
Measure of how robust the system, structure, or process is to perturbations. Low stability means small changes can cause large deviations.
