Application and Usage
E339 is the designation used in the European Union for a class of food additives derived from phosphoric acid and sodium. It can exist in several forms, including monobasic, dibasic, and tribasic sodium phosphates. Each variant offers unique properties that cater to different applications. In the food industry, E339 is widely recognized for its ability to improve texture, extend shelf life, and enhance moisture retention in products.
Applications in Water Treatment
1. Inorganic Chemicals This category includes acids, bases, and salts, which are essential in various industrial processes. For instance, sulfuric acid (H₂SO₄) is used in the production of fertilizers, in petroleum refining, and in wastewater treatment. Other inorganic chemicals, such as sodium hydroxide (lye), are critical in the manufacturing of soap and paper.
Unlike direct food additives, indirect food additives are not intentionally added to food. Instead, these substances may come into contact with food during processing, packaging, or storage. They can include residues from packaging materials, lubricants used in processing equipment, and even substances from cleaning agents used in food preparation areas.
