About This Product
Sodium dehydroacetate is the sodium salt of dehydroacetic acid, formula C8H7NaO4, with CAS number 4418-26-2 and the additive number E266. It is supplied as a white crystalline powder, readily soluble in water and considerably more soluble than the parent acid.
Its technical interest lies in its pH range. Benzoate, sorbate and propionate all depend on an undissociated acid fraction that collapses as pH rises, which confines them to acidic foods. Sodium dehydroacetate retains useful activity up to around pH 7, and it is effective against a broad spectrum of moulds, yeasts and bacteria, which makes it applicable to products too near neutral for the conventional options. It is also stable to heat and light. The decisive constraint is regulatory rather than technical: approval for food use varies substantially between jurisdictions, it is permitted in some Asian markets but is not an authorised food additive in the European Union, where it is used in cosmetics instead. Permitted status, categories and maximum levels must therefore be confirmed for the destination market before it is designed into a formulation.
Where permitted it is used in baked goods, pickled vegetables, soy and fermented products, beverages and cheese, and it is widely used in cosmetics and personal care.
Bio Green Foods supplies sodium dehydroacetate to specification on assay, loss on drying, pH, chlorides and heavy metals, with permitted-use status confirmed for the destination market before supply.
