Potato Safety Inspection
Detect malachite green dye and chemical sprout inhibitors in potatoes
Inspection Guide
Potato Freshness & Safety Check
Potatoes are often treated with chemicals to hide age, blemishes, and prevent natural sprouting.
**1. The Peel Test:**
Use a vegetable peeler to remove a thin layer of skin. If you notice a greenish tint just under the surface (especially if the outside looks normal), it indicates malachite green treatment. Natural potatoes have uniform color throughout.
**2. The Sprout Check:**
Natural potatoes develop sprouts (eyes) over time. If a potato looks old but has zero sprouts and no eye indentations, it has likely been treated with harmful sprout inhibitors.
**3. The Shine Test:**
Run your fingers across the potato skin. If it feels unnaturally smooth, waxy, or shiny, it may have been polished with chemicals or wax. Natural potatoes have a matte, slightly rough texture.
**4. The Wet Cloth Test:**
Rub the potato with a damp white cloth. Any color transfer (especially green) indicates chemical coating.
**Safety Tip:**
Always peel potatoes before cooking. Wash thoroughly and soak in salted water for 10 minutes if you suspect chemical treatment.
Quick Safety Tips
- Peel and check for greenish tint underneath
- Old potatoes should have sprouts - absence indicates chemicals
- Check for unnatural shine or wax coating
- Always peel before cooking if suspicious
