sci.freezing-point-depression-food Calculator
Calculates freezing point depression of food products from water activity using cryoscopic methods and predicts ice crystal formation temperatures. Pure water freezes at 0 °C — 1% NaCl solution freezes at −0.6 °C; 20% sugar solution at −2.0 °C; ice cream mix typically freezes below −2 to −4 °C.
Inputs
Molality Mol Kg
Reference formula or conversion factor shown for context.
Kf
Reference formula or conversion factor shown for context.
Water Activity
Reference formula or conversion factor shown for context.
Results
freezing point depression ΔTf (°C)
Sample size or count used in the calculation.
predicted freezing point Tf (°C)
Sample size or count used in the calculation.
Tf from water activity (°C)
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.
ΔTf = Kf · m
Reference formula or conversion factor shown for context.
Kf for water = 1.86 K·kg/mol
The value at the specified point or condition.
