E332 – Potassium Citrates
CitrateDescription
White, odorless, hygroscopic granules or powder
Notes
Potassium citrates are white, odorless powders that readily absorb moisture from the air (which is what 'hygroscopic' means). They're made by combining citric acid—the same natural acid found in citrus fruits—with potassium compounds. Like sodium citrates, they're produced commercially by neutralizing citric acid, but in this case with potassium hydroxide or potassium carbonate instead of sodium compounds. These additives work as acidity regulators, helping to control and buffer the pH levels in various foods to keep them stable and safe. Potassium citrates are commonly used in soft drinks, fruit juices, and other beverages, as well as in jams, jellies, and processed foods where maintaining the right acidity level is important for both flavor and preservation. They can also act as emulsifiers in some applications, helping ingredients mix together smoothly. Potassium citrates are safe, natural-origin additives that are suitable for vegetarians, vegans, and most dietary restrictions including religious requirements. Unlike sodium citrates, these don't contribute to sodium intake, making them a preferred choice for products targeting people who need to limit their sodium consumption. They're approved by food safety authorities worldwide and are considered very safe for regular consumption.
