Toor Dal (Pigeon Peas) Safety Inspection

Toor Dal (Pigeon Peas) is commonly adulterated with Metanil Yellow, a toxic textile dye, and Kesari dal which causes lathyrism (a paralysis condition). **1. The Color Test:** Natural Toor Dal has a dull, natural yellow color with slight variations. If the dal is unnaturally bright yellow, almost fluorescent, or has a uniform intense yellow color, it likely contains Metanil Yellow dye. **2. The Water Soak Test:** Take a handful of dal and soak in water for 30 minutes. Natural Toor Dal will release minimal color. If the water turns bright yellow or orange, it indicates artificial dye presence. **3. The Wet Cloth Rub Test:** Take a few dal grains and rub them vigorously with a wet white cloth. If yellow color transfers to the cloth, it's a clear sign of Metanil Yellow dye. Natural dal won't leave significant color stains. **4. The Hydrochloric Acid Test (Advanced):** Add 5ml of diluted HCl to dal soaking water. If the water turns pink or red, it confirms Metanil Yellow presence. This test requires caution with acid handling. **5. Visual Shape Inspection:** Kesari dal (which causes paralysis) looks very similar to Toor dal but is slightly flatter and more angular. Natural Toor dal grains are more rounded and consistent in shape.
