Microbiological Criteria
Inorganic salts do not support microbial growth and do not pose any microbial risks since their production processes involve high heat and acidic/alkaline conditions.
Intended Use
- Bakery products (baking powder, cakes, biscuits, muffins, pancakes): controlled leavening acid providing consistent CO2 release.
- Processed meat and poultry: improves water-holding capacity, yield and texture.
- Seafood processing: moisture retention and texture stabilization.
- Potato products: minimizes discoloration during processing.
- Dairy and powdered food products: pH adjustment and stabilization.
- Food industry: sequestrant, buffering agent and processing aid.
- Industrial phosphate formulations requiring controlled acidity.
Additional Information
- Shelf Life: 2 years from the Production Date.
- Applicable Standards: Turkish Food Codex (TGK), Regulation (EC) No 1333/2008, Food Chemicals Codex (FCC), where applicable.
- Legal Requirements: Product name, ingredients, quantity, company name, registration number, batch number, recommended consumption date or expiry date.
- Storage Rules: Store in a dry environment away from moisture. Keep away from oxidants.
- Transportation Rules: Transport vehicles (truck, railcar, container, etc.) must be clean, dry, and covered with a tarpaulin during transportation.
