Quick Facts
- FSSAI data consistently shows spice powders among the top adulterated food categories in India — particularly chilli, turmeric, coriander, and cumin powders
- Brick powder is the most common adulterant in chilli powder — it is the same red colour, has similar texture, and adds weight cheaply. Water float test detects it instantly
- Papaya seeds are dried, powdered, and added to black pepper — a common practice that can be detected by the water float test (pepper floats; papaya seeds sink)
- Metanil yellow (an industrial dye) is used in cumin, coriander, and turmeric powders to enhance yellow colour — it is carcinogenic and banned as a food additive
- Sudan dye (an industrial oil-soluble dye) has been found in chilli powder in India — it is a Group 3 carcinogen and specifically targetted by FSSAI enforcement
- Whole spices (not powdered) are dramatically safer — it is almost impossible to hide adulteration in intact whole spices. Buy whole and grind at home
Why Spices Are So Heavily Adulterated
Spice powders are an ideal target for adulteration because:
- High value — spices are expensive; even small quantities fetch high prices
- Powder form — adulterants can be mixed invisibly into powder
- Complex flavour — minor dilution is difficult for consumers to detect
- High consumption — Indian households use spices daily, creating high-volume, high-frequency purchases
Spice-by-Spice Adulterant Guide
Spice Adulteration — What Is Added to Each Spice
| Spice | Common Adulterants | Health Risk | Simple Test |
|---|---|---|---|
| Chilli powder (lal mirch) | Brick powder, sawdust, artificial red dye, Sudan dye | Sudan dye: carcinogenic | Water test — brick sinks and turns red |
| Turmeric powder | Lead chromate, metanil yellow, chalk, starch | Lead chromate: carcinogen/neurotoxin | Water test — red tinge = lead chromate |
| Coriander powder (dhania) | Dung powder, chalk, colour dyes | Contamination risk | Water test; smell test |
| Cumin (jeera) | Grass seeds (coloured), sand, artificial colour | Low toxicity; adulteration fraud | Water float — cumin floats, sand sinks |
| Black pepper | Papaya seeds (dried), light berries, mineral oil coat | Low toxicity; quality fraud | Water float — papaya seeds sink |
| Asafoetida (hing) | Gum, starch, non-edible binders | Allergy risk from non-food gums | Flame test; water dispersal |
| Cardamom | Spent cardamom pods (flavour removed), filler seeds | Low toxicity; quality fraud | Chew test — no flavour = spent pods |
The safest approach for all spices: buy whole, not powdered. Grind at home as needed.
Home Tests for Common Spice Adulteration
Home Test: Chilli Powder — Water Float Test (Brick Dust)
Steps
- 1 Add 1 tsp of chilli powder to a glass of water
- 2 Stir gently and wait 2 minutes
- 3 Observe what floats and what sinks
Pure / Pass
Pure chilli powder floats on the water surface as red particles. The water below may be lightly coloured red from the natural pigment capsanthin.
Adulterated / Fail
Adulterated chilli with brick powder: a red sediment sinks to the bottom (brick is heavier than chilli). The water may turn red from artificial dye leaching out immediately.
Home Test: Black Pepper — Water Float Test (Papaya Seeds)
Steps
- 1 Place 1 tsp of whole black pepper in a glass of water
- 2 Stir and observe which grains float and which sink
- 3 Pure pepper should float; heavier adulterants sink
Pure / Pass
Genuine black pepper floats on the water surface — pepper is light and has a low density.
Adulterated / Fail
Papaya seeds (heavier than black pepper) sink to the bottom. If you see a proportion of seeds sinking while others float, adulteration is present. Light-coloured seeds at the bottom are papaya seeds.
Home Test: Coriander Powder — Smell Test
Steps
- 1 Rub a small amount of coriander powder between your palms
- 2 Smell immediately — fresh coriander has a distinct citrusy, warm aroma
- 3 Compare the aroma intensity to pure ground coriander
Pure / Pass
Pure coriander powder has a strong, distinctive warm-citrus aroma that intensifies when rubbed (releases essential oils).
Adulterated / Fail
Adulterated coriander with dung powder or filler materials has a muted, flat, or off-putting smell with little or no coriander aroma.
Home Test: Asafoetida (Hing) — Flame Test
Steps
- 1 Place a small pinch of hing on a spoon
- 2 Hold a burning match or lighter near it (do not put it in a flame)
- 3 Observe whether it catches fire and burns
Pure / Pass
Pure asafoetida catches fire and burns with a bright flame, leaving minimal ash. This is because pure hing is a resin with significant combustible content.
Adulterated / Fail
Adulterated hing with excessive starch or non-combustible fillers does not catch fire or burns very poorly. Heavy adulterants leave significant white ash.
The Case for Whole Spices
The single most effective protection against spice adulteration is buying whole spices and grinding at home:
- Whole turmeric root — cannot hide lead chromate inside intact root
- Whole black pepper — immediately visible if papaya seeds or other items are mixed
- Whole cumin seeds — adulterant grass seeds are visually distinct from genuine cumin
- Whole coriander seeds — chalk and dung cannot be hidden in intact seeds
A small home spice grinder (₹500–1500) pays for itself in food safety and freshness within months.

Q Are branded, packaged spice powders safer than loose market spices?
Are branded, packaged spice powders safer than loose market spices?
Generally yes — branded packaged spices from FSSAI-licensed manufacturers are subject to testing and have legal accountability. However, branded does not mean 100% safe: multiple FSSAI actions have been taken against branded spice companies including some major national brands. The safest option is: FSSAI-licensed + published third-party lab reports + organic certification (for pesticide risk). The riskiest: loose spice powders from open bins in wholesale markets with no traceability.
Q If a spice has an FSSAI logo on the packaging, is it safe?
If a spice has an FSSAI logo on the packaging, is it safe?
The FSSAI logo means the manufacturer has a valid FSSAI license — it is a legal requirement, not a quality seal. It does not mean the specific batch was tested or that the product is free of adulterants. FSSAI conducts random sampling from the market, so most manufacturers are not regularly tested. Having an FSSAI license is necessary but not sufficient. Look for brands that go beyond FSSAI compliance to publish their own third-party lab test results for specific adulterants relevant to each spice.
