Potassium sulfate is used in many industries and may be known by many names. It is referred to as aluminum potassium sulfate in the food industry, and this crystalline salt is commonly used in water purification and food preparation. Manufacturers of soda and other beverages recognize consumer demand for purity in drinking water, and being able to provide products composed of the purest water possible may directly affect customer satisfaction and retail profitability. Various public health organizations recognize safe levels for ingesting potassium sulfate, but studies continue to provide new information that businesses and consumers may need in order to assess the risks and benefits of potassium sulfate.
Water is purified by removing large particles after they have been suspended, and the addition of potassium sulfate is what causes the unwanted particles to stick together and form larger and heavier particles. The particles are removed through filtration or sedimentation, and this helps remove microscopic molecules and fine solid pollutants that may affect the safety, smell, and taste of water used to produce soda and other beverages. The Food and Drug Administration notes that aluminum may be found in many foods at varying levels, and the organization also reports that potassium sulfate may be safe if taken in accordance with recognized limits related to body weight.
Potassium sulfate dissolves easily in water and may be very useful for creating the carbon dioxide properties that characterize popular carbonated beverages. Many medications designed to combat indigestion and other types of gastrointestinal upset may contain aluminum potassium sulfate, and this is why various health organizations may advocate further regulation of this drink ingredient. Some groups have voiced concern over the potential transmission of aluminum compounds from paper packaging material but there appears to be no direct evidence to support this assertion. Potassium sulfate continues to be considered as a viable drink ingredient.
