Broad spectrum in a narrow regulatory window
It is effective against bacteria, yeast and mould, which is unusual for a single compound, but it is not approved in every market. Check the destination regulation before formulating.
Frequently used where sorbate and benzoate fall short
In fillings and sauces with pH near 5, sorbate is weak and benzoate inactive, so dehydroacetate fills the gap at a lower dose than either.
Typical Applications
- Bakery fillings and toppings — 0.05-0.1 percent extends ambient shelf life.
- Sauces and dressings — 0.1-0.2 percent in the pH 4.5-6.0 range.
Frequently Asked Questions

Not as a food additive in all categories. Verify before use.
How does it taste?
Essentially tasteless at effective dosage, unlike benzoate.
Can it replace sorbate?
In some systems at lower dose, but the regulatory status usually decides.
