Disodium Phosphate (DSP), also known as sodium phosphate dibasic, is a food additive frequently used in food and beverage production. It serves multiple functions and is primarily used as a buffering agent, emulsifier, sequestrant, or as a pH stabilizer. DSP helps stabilize and improve the texture of processed foods, such as cheese, canned soups, and sauces, by acting as an emulsifying agent. It allows the proper blending of ingredients that do not naturally mix well. It acts as a pH stabilizer by controlling and maintaining the acidity or alkalinity of food products. DSP is often used in various soft drinks and powdered beverage mixes to balance the flavor and acidity levels. DSP serves as a binding agent in meat products, including processed meats, sausages, and canned meats. It enhances water retention capability, improves juiciness, and prevents product separation. In some meat and fish products, DSP can be used as a curing agent to retain moisture, improve flavor, and extend shelf life. DSP is considered a source of phosphorus, an essential mineral required for various bodily functions. It is sometimes added as a nutrient supplement to beverages, dairy products, and breakfast cereals to enhance the phosphorus content. It is worth noting that DSP should be used within the approved limits defined by regulatory authorities, as excessive or inappropriate use may have adverse effects on human health.
