Direct product answer
What is food grade sodium citrate?
The supplied product is described as trisodium citrate dihydrate Na3C6H5O7·2H2O. Codex identifies trisodium citrate as INS 331(iii).
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 Citrate applications
Confirm legal use, dosage, technical performance and sensory impact in the finished product.
Food stabilization
May support ionic balance and stability in compatible formulations.
Flavor systems
Citrate can modify perceived acidity and salt balance.
Dairy and processed foods
Evaluate protein, mineral and pH interactions in the complete product.
Brewing
The supplied information identifies brewing use; confirm process objectives and grade.
Dry blends
Specify hydrate form, flow, dissolution and moisture control.
