Direct product answer
What is food grade potassium citrate?
The supplied product is potassium citrate monohydrate K3C6H5O7·H2O, CAS 6100-05-6. Tripotassium citrate is identified by Codex as INS 332(ii).
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 Potassium Citrate applications
Confirm legal use, dosage, technical performance and sensory impact in the finished product.
Food stabilization
May support acidity and ionic balance in suitable formulations.
Potassium fortification
Can contribute potassium where nutritional and regulatory requirements allow.
Processed foods
Assess flavor, pH response and interactions with proteins and hydrocolloids.
Dry blends
Confirm hydrate form, flow, moisture pickup and dissolution.
Premixes
Specify potassium basis, particle size and target standard.
