Formula and methodology
Formula: Saponification value = (Vblank−Vsample) × N × 56.1/sample mass, in mg KOH/g.
The blank correction estimates the KOH consumed by saponification and expresses it per gram of tested material.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Blank titration volume — mL; minimum 1.0E-6; maximum 1000000000
- Sample titration volume — mL; minimum 0; maximum 1000000000
- KOH normality — N; minimum 1.0E-6; maximum 100
- Oil or fat sample mass — g; minimum 1.0E-6; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Blank titration volume | 25 |
| Sample titration volume | 15 |
| KOH normality | 0.5 |
| Oil or fat sample mass | 2 |
Saponification value = 140.25 mg KOH/g.
Assumptions and limits
- Blank and sample titrations use the same KOH solution and endpoint method.
- The blank volume is at least as large as the sample volume.
- This is an analytical calculation, not a food-safety grade, authenticity decision, or process specification.
