Purpose and Function

Sodium aluminium phosphate is commonly used as an acidity regulator in food applications:

  • Acidity Regulator: It helps maintain pH levels in food products, contributing to flavor and preservation.
  • Improves Texture: Enhances the texture of food products, particularly in baked goods.
  • Nutritional Enhancer: It provides sodium and aluminium, which can contribute to dietary needs.

Potential Risks and Side Effects

Sodium aluminium phosphate is generally regarded as safe for consumption. However, some considerations include:

  • Gastrointestinal Issues: Excessive intake may lead to gastrointestinal discomfort, including bloating or gas, particularly for those sensitive to sodium or aluminium.
  • Allergic Reactions: Rarely, individuals may experience allergic reactions to sodium aluminium phosphate, particularly those with sensitivities to aluminium compounds.
  • Contaminants: Sourcing from reputable suppliers is essential to minimize the risk of contaminants in food formulations.
