Chickpeas (Chana) Safety Inspection

Chickpeas, especially the yellow varieties (Chana Dal/Kabuli Chana), are often treated with Metanil Yellow (a toxic textile dye) to look more attractive and uniform. 1. The Hydrochloric Acid Test (Dye Detection): In a test tube, take a small sample of chickpeas and add a little water. Add a few drops of concentrated Hydrochloric Acid (HCl). If the solution turns pink or magenta, Metanil Yellow is present. Pure chickpeas will not change color. 2. The Water Soak (Color Bleed): Soak chickpeas in warm water for 15 minutes. If the water turns bright yellow immediately, suspect artificial dyes. Natural chickpea color leaches very slowly and turns the water a faint, pale yellow. 3. The Rub Test: Rub dry chickpeas vigorously between your palms. If they leave a bright yellow powdery residue on your skin, it is a clear sign of dye coating. 4. The Grit and Stone Check: Spread a handful of chickpeas on a white plate. Look for small, stone-like particles that match the color of the chickpeas. Some retailers add matching stone dust or small pebbles to increase weight.
