Green Peas Safety Inspection

Green peas, especially when sold as shelled kernels, are frequently treated with Malachite Green or Copper Sulfate to maintain an unnaturally vibrant green color, even after they have lost their freshness. 1. The Cotton Rub Test (Kernels): Take a few green peas and rub them with a wet cotton ball. If the cotton turns green or bluish-green, artificial dye has been applied. Natural pea color does not transfer easily. 2. The Water Wash (Color Bleed): Soak a handful of peas in a glass of warm water for 15 minutes. If the water turns bright green or bluish, artificial coloring (Malachite Green) is confirmed. Natural chlorophyll remains inside the cells and won't leach. 3. The Texture Check: Gently press a pea. A naturally fresh pea is slightly firm but yielding. If the pea feels "stiff" or "rubbery" while being a vibrant green, it may be old stock chemically "refreshed." 4. The Taste Profile: Fresh green peas have a distinct, sweet, and nutty flavor. If they taste "chalky," bitter, or have a chemical after-taste, suspect dyes or preservative treatments.
