Turnip (Shalgam) Safety Inspection

Turnips, especially those with purple tops, are sometimes treated with Rhodamine B dye to look more vibrant, while the white bottoms may be bleached for a clean look. 1. The Cotton Rub Test (Purple Top): Take a cotton ball soaked in water or liquid paraffin and rub the purple/pink skin at the top of the turnip. If the cotton turns pink or magenta, artificial dye like Rhodamine B has been applied. 2. The Snap and internal Check: Snap the turnip in half. The interior should be crisp and a uniform creamy white. If the core looks translucent, "woody," or has a chemical smell despite a bright exterior, suspect chemical refreshing. 3. The Surface Texture: Examine the turnip for an unnaturally "waxed" or "polished" look. Natural turnips have a slightly matte texture and some soil residue. Perfectly clean and vibrant roots are often chemically washed or dyed. 4. The Water Soak: Soak sliced turnips in a glass of cold water for 15 minutes. If the water turns pink or purple immediately, artificial dyes have been used. Natural pigments leach very slowly.
