Product overview
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 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 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.
Commercial specifications
Food grade Potassium Citrate reference specification
These commercial reference limits are separate from batch COA results. Agree the grade, analytical basis and applicable standard before ordering.

Specification note: The loss-on-drying, acid-insoluble-matter and lead values have unresolved field/limit assignments; clarity has no established acceptance criterion. These entries are not contractual limits. Require a signed specification defining the correct field, unit, method and limit before acceptance. FCC-IV and USP-24 are historical editions, not evidence of conformity with current standards.
