Guía de Pureza del Chile en Polvo: Detecta Polvo de Ladrillo y Rojo Sudán

Chili powder is frequently adulterated with brick dust to increase weight or treated with industrial red dyes like Sudan Red to look vibrant and "spicy."

1. The Water Sediment Test (Brick Dust Detection):
Add 1 tsp of chili powder to a glass of water. Pure chili powder will float on the surface or settle slowly. If a heavy, gritty red sediment (brick dust) settles instantly at the bottom, it is adulterated.

2. The Rub Test (Dye Detection):
Take a small amount of chili powder and rub it on a piece of white paper. If the powder leaves a bright red or pink stain that is hard to rub off, suspect artificial dyes. Natural chili leaves a brownish-red stain.

3. The Glass of Water Check:
Sprinkle chili powder on the surface of water. Pure powder stays on top. If you see bright red "streaks" or color leaching rapidly into the water as the powder sinks, suspect artificial coloring.

4. The Taste Profile:
Pure chili powder has a sharp, pungent heat that builds up. If it tastes "earthy," "chalky," or has a chemical after-taste without much heat, it contains brick dust or fillers.
