Direct product answer
What is food grade sodium propionate?
Food grade sodium propionate, also called sodium propanoate, is INS 281, CAS 137-40-6 and formula C3H5O2Na.
The supplied commercial limits must be matched to the exact grade, intended food category and destination-market rules. A product name alone does not establish regulatory conformity.
Application screening
Common food grade Sodium Propionate applications
Confirm legal use, dosage, technical performance and sensory impact in the finished product.
Cakes and pastries
Used in suitable bakery products after confirming dosage, pH and sensory impact.
Bakery premixes
Confirm dispersion, compatibility and declared preservative requirements.
pH-dependent preservation
Preservative performance depends on product pH, water activity and process hygiene.
Shelf-life programs
Validate effectiveness through challenge or shelf-life testing.
Industrial baking
Specify particle size, addition point and production conditions.
