Potassium Citrate Monohydrate (E332) is a versatile food-grade potassium salt of citric acid — used as a buffering agent, emulsifier, sequestrant, acidity regulator and mineral source. Approved under FSANZ Standard 1.3.1, it is widely used in sports drinks and electrolyte formulas as a bioavailable potassium source, in processed cheese as an emulsifying salt, in jams and confectionery for pH control, and in food manufacturing for its excellent buffering capacity at near-neutral pH.

Recommended usage levels
| Application | Usage level | Notes |
|---|---|---|
| Sports / electrolyte drink | 0.1 – 0.5% | Potassium source; mild alkaline buffer — dissolve in water |
| Processed cheese / cheese sauce | 1 – 3% | Emulsifying salt alongside sodium citrate |
| Jams & preserves | 0.1 – 0.3% | pH buffering and pectin activation |
| Beverages / pH regulation | 0.05 – 0.3% | Adjust acidity; neutralises citric acid sharpness |
| Confectionery / hard candy | 0.1 – 0.5% | Sequestrant and pH control |
| Fermentation media | 0.1 – 0.5% | Potassium and citrate source for culture media |
| Antioxidant synergist | 0.01 – 0.1% | Chelates metals; enhances antioxidant effectiveness |
| General pH buffering | As per formulation | Target pH 5.5–8.5; verify with calibrated meter |
Potassium sources comparison
| Ingredient | K content | Taste | Best for |
|---|---|---|---|
| Potassium Citrate (E332) | ~38.3% | Mild, pleasant | Sports drinks, cheese, food |
| Potassium Chloride (E508) | ~52.4% | Bitter, metallic | Salt substitute (masked) |
| Potassium Bicarbonate (E501) | ~39.1% | Slightly salty | Leavening, pH adjustment |
| Potassium Phosphate (E340i) | ~28.7% | Mild | Buffering, mineral source |
💡 Formulation tip: Potassium Citrate is the preferred potassium source for sports and electrolyte drinks — it is better tolerated than Potassium Chloride (which can taste bitter) and provides both potassium and citrate in a single ingredient. A typical electrolyte formula combines Potassium Citrate with Sodium Citrate and Sodium Chloride for a balanced electrolyte profile. For processed cheese, combine with Sodium Citrate (E331) in a 1:2 ratio for an emulsifying salt blend that controls both pH and melt behaviour.
Dissolution & handling
- Dissolve in warm water (40–60°C) with stirring for fastest dissolution
- Fully water soluble — solutions should be clear
- Verify pH after dissolution with a calibrated pH meter
- For pH neutralisation of citric acid, add Potassium Citrate gradually until target pH is reached
- Prepared solutions are stable for up to 2 weeks refrigerated in sealed containers
- Slightly hygroscopic — keep container sealed to prevent caking
Storage
- Store in a cool, dry place away from direct sunlight and moisture
- Keep container tightly sealed — slightly hygroscopic
- Shelf life: 24 months from manufacture date when stored correctly
- Keep away from strong acids and oxidising agents

Frequently asked questions
Potassium Citrate Monohydrate (E332) is used as a buffering agent to control and stabilise pH, as an emulsifying salt in processed cheese, as a bioavailable potassium source in sports and electrolyte drinks, as a sequestrant to chelate metal ions and prevent oxidation, and as a pectin activator in jams and preserves. It is one of the most versatile potassium salts in food manufacturing.
Potassium Citrate Monohydrate contains approximately 38.3% potassium by weight. This makes it a highly concentrated and bioavailable potassium source compared to Potassium Chloride (52.4% K but poor taste) or Potassium Bicarbonate (39.1% K). For electrolyte formulation, 1g of Potassium Citrate Monohydrate provides approximately 383mg of potassium.
Potassium Citrate (E332) and Sodium Citrate (E331) are structurally similar — both are citrate salts used as buffers, emulsifiers and sequestrants. The key difference is the cation: Potassium Citrate provides potassium, while Sodium Citrate provides sodium. Both are used together in electrolyte drinks and processed cheese formulas. Sodium Citrate is more widely used and slightly less expensive; Potassium Citrate is essential where potassium fortification is required.
A 1% solution of Potassium Citrate Monohydrate produces a pH of approximately 8.0–9.0 (alkaline). It acts as an effective buffer across pH 5.5–8.5. To achieve a specific target pH, combine with Citric Acid and adjust to the desired level using a calibrated pH meter.
Yes. Potassium Citrate is approved under FSANZ Standard 1.3.1 as E332. It is also approved in the EU as E332(iii), GRAS in the USA and listed in the Codex Alimentarius as INS 332(iii). It is one of the most widely approved potassium salts in global food regulation.
Yes. Email info@benario.com.au with your order number for a batch-specific Certificate of Analysis including assay, potassium content, heavy metals and identity confirmation.
The 200g pack suits home brewers, R&D applications and small-batch testing. The 500g and 1kg are ideal for regular commercial production, sports nutrition manufacturers and food producers.
