Synthetic dye

Plain-language explanation

E132, also known as Indigotine or Indigo Carmine, is a synthetic blue food coloring used in products like sweets and beverages. It is produced through chemical synthesis and does not come from animal or insect sources, making it generally considered halal by major certification bodies like JAKIM, MUI, and MUIS. However, some strict interpretations may require verification that no alcohol-based solvents were used in its production, though this is rarely an issue for commercial food-grade E132. Always check for halal certification on the product label to ensure compliance with your dietary standards.
