Cabbage Freshness and Dye Detection
Cabbage is often sprayed with dyes like Malachite Green to look vibrant green and copper sulfate for freshness.
1. The Water Soak Test:
Remove a few outer leaves and soak them in a bowl of water for 30 minutes. If the water turns greenish, it indicates artificial dyes. Natural cabbage color stays in the leaves.
2. The Wet Cloth Test:
Rub the outer leaves with a wet white cloth. If green color transfers, it's a sign of Malachite Green or other dyes used to mask wilting.
3. Inner vs. Outer Color:
Cut the cabbage in half. Natural cabbage is bright green on the outside but fades to pale cream/white in the center. If the green color is uniforms throughout or looks "painted" on the outer layers, it's suspicious.
4. The Scent Test:
Natural cabbage has a mild, fresh aroma. Chemically treated ones may have a faint metallic or chemical odor from sulfate sprays.
