A sodium benzoate addition and a benzoic-acid-equivalent quantity are different numbers. Put the substance, units and conversion basis next to every result before comparing a formulation record with an external requirement.
Check the source’s exact language
The Codex GSFA benzoates group organises provisions by additive group and food category. It is a reference for checking the applicable wording, not blanket permission for a product in every country. This article supplies arithmetic, not a legal use limit.
Using rounded formula masses of 144.11 for sodium benzoate and 122.12 for benzoic acid, the acid-equivalent factor is 122.12 / 144.11 ≈ 0.8474. A hypothetical 100 mg of pure sodium benzoate therefore corresponds to approximately 84.74 mg of benzoic acid on this stoichiometric basis. The example is not a suggested addition rate.
| Ledger field | Meaning |
|---|---|
| Purchased ingredient mass | Mass of the offered material |
| Sodium benzoate mass | Ingredient mass adjusted for its confirmed composition |
| Benzoic-acid-equivalent mass | Sodium benzoate mass multiplied by the stated factor |
Keep the conversion direction visible
If the starting number is an acid-equivalent quantity and you need sodium benzoate mass, divide by the factor rather than multiply. Keep units unchanged through the calculation and use the actual ingredient assay basis where relevant. Record any finished-product yield or dilution separately; chemistry conversion does not account for evaporation or process loss.
Have the responsible regulatory specialist verify the current destination-market provision, food category and expression basis. For purchasing, request identity and composition evidence for the offered lot. An analytically correct conversion can still be applied to the wrong category or regulatory text, so the spreadsheet should retain both the calculation and its intended use.
