Product overview

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 commercial reference 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.

Bread and rolls

Evaluate mold control, flavor and shelf life in the actual bread formulation.

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.

Commercial specifications

Food grade Sodium Propionate reference specification

These commercial reference limits are separate from batch COA results. Agree the grade, analytical basis and applicable standard before ordering.
