Cheese Moisture Adjustment Calculator

Work out cheese moisture adjustment instantly with clear inputs, formula shown and shareable results.

About Cheese Moisture Adjustment Calculator

Because solids are conserved, the mass at a target moisture is solids divided by the dry matter fraction at that target. Two derived indices govern cheese identity: fat in dry matter, which defines the fat class, and moisture in the non-fat substance, which defines whether a cheese is hard, semi-hard or soft.

Formulas

Moisture adjustment

Solids = mass x (100 - moisture) / 100; mass at target = solids x 100 / (100 - target moisture)

Cheese indices

FDM % = fat x 100 / (100 - moisture); MNFS % = moisture x 100 / (100 - fat)

Worked example

With the default values below, Cheese Moisture Adjustment Calculator returns Water To Remove of 6.452. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
Cheese compositional standards including fat in dry matter and moisture limits are legally defined for named varieties. Verify against the applicable food standard.

Frequently Asked Questions

Why is MNFS more useful than moisture alone?

It measures the water available in the protein matrix, which controls texture, ripening rate and microbial activity independently of how much fat is present. Cheese standards are written on it for that reason.

How is moisture reduced in practice?

By finer curd cutting, higher cooking temperature, longer stirring, more pressing and lower pH at draining. Each lever also affects texture and flavour, so they are not interchangeable.
