How to Spot Adulterated Spices in 60 Seconds

8 min readApr 12, 2026

From chalk dust in cumin to artificial colour in chilli — a practical field guide to testing what's in your masala dabba.

Spice adulteration is one of India's oldest food fraud problems — and one of its least-discussed. FSSAI estimates that up to 30% of branded spice products on Indian retail shelves contain detectable adulterants. Here is a practical guide to testing what you buy.

The Water Test (Universal)

Drop a small pinch of any ground spice into a glass of cold water and stir gently. Pure spices suspend briefly, then slowly sink. Chalk powder and rice flour sink immediately. Artificial dyes bleed instantly, turning the water bright red or orange.

Quick Test

This test takes 30 seconds and requires nothing but a glass of water. Make it a habit every time you open a new packet.

Chilli Powder: The Most Adulterated Spice

  • Sudan Red dye: water turns crimson rather than pale orange
  • Brick dust: gritty texture when rubbed between fingers; sinks fast in water
  • Paprika mixed with talcum: slippery feel, faint chemical smell
  • Artificial colour: colour bleeds to hands immediately when touched

Turmeric Powder

Add a teaspoon of turmeric to a glass of water. Pure turmeric turns the water a gentle golden yellow. Metanil yellow (a banned industrial dye) turns water intensely bright yellow-orange almost instantly. Starch adulterants will make the mixture thick and cloudy.

Cumin Seeds

Roll a few seeds between your palms. Colour transfer onto skin indicates artificial dye. Genuine cumin has a distinctive warm, earthy aroma — 'cumin' that smells only grassy is often grass seeds. Rub with vegetable oil: real cumin releases a strong, complex fragrance within seconds.

The best spice test is your nose. If it doesn't smell like the dish it is meant to make, it probably won't make that dish well.

What to Look For on Labels
