Leafy Greens (Spinach/Palak) Safety Inspection

Leafy greens like Spinach (Palak) are high-risk vegetables often sprayed with Copper Sulfate (Nila Thotha) or Malachite Green to maintain an unnaturally vibrant green look even after wilting. 1. The Cotton Rub Test: Take a cotton ball soaked in water or liquid paraffin and rub the surface of the leaves. If the cotton turns green or bluish-green, artificial dyes like Malachite Green or Copper Sulfate have been applied. 2. The Water Wash (Color Bleed): Soak the leaves in a bowl of water for 15 minutes. If the water turns bluish-green or a vibrant, unnatural green, suspect chemical coloring. Natural chlorophyll does not leach into cold water easily. 3. The Texture Check: Naturally fresh leafy greens wilt within 3-4 hours at room temperature. If the greens look vibrant and "stiff" but have no root hydration or have been out for a long time, suspect chemical "refreshing" agents. 4. The Stem Color: Check the cut end of the stems. If they show a bluish or deep green tint that looks different from the leaf color, it indicates the absorption of Copper Sulfate solutions.
