Food Adulteration in India: Simple Home Tests That Actually Work
Food adulteration is a real problem in India, and FSSAI publishes a free manual — DART, Detect Adulteration with Rapid Test — containing over 50 simple tests you can run at home on milk, ghee, spices and oils. They are genuinely useful for spotting obvious adulteration. What they cannot do is detect heavy metals, pesticide residue or verify protein content, which need a lab.
- FSSAI's DART manual compiles 50+ household tests for common adulterants, published free by the regulator[1].
- Covers milk (water, starch, detergent, urea), spices (lead chromate in turmeric, brick powder in chilli), and oils[1].
- These tests spot crude adulteration; they cannot detect heavy metals, pesticides or verify a protein claim.
- For supplements, the meaningful checks are the FSSAI licence number, full nutrition panel, and third-party lab testing.
- A short ingredient list you can read is worth more than any home test.

FSSAI publishes the tests itself
This is not widely known: India's food regulator produces a free manual called DART — Detect Adulteration with Rapid Test, compiling common quick tests you can perform at home to check for adulterants[1]. It covers over 50 tests across milk and dairy, spices, oils and fats, sugar and more, with step-by-step instructions.
If you are worried about what is in your food, start with the regulator's own manual rather than social media advice.
Tests worth knowing
| Food | Adulterant | Home test |
|---|---|---|
| Milk | Added water | Put a drop on a polished slanting surface. Pure milk stays or flows slowly, leaving a white trail[1] |
| Milk | Starch | Add a few drops of iodine solution — blue colour indicates starch |
| Milk | Detergent | Shake an equal mix of milk and water; dense persistent lather suggests detergent |
| Ground spices | Sawdust, bran | Sprinkle on water. Pure spice does not leave sawdust or bran floating on the surface[1] |
| Turmeric | Lead chromate | Covered in the DART manual — a genuine safety concern, not a purity nicety[1] |
| Chilli powder | Brick powder | Stir in water; brick powder settles as gritty red sediment |
| Ghee | Vanaspati / starch | Iodine or hydrochloric-acid based tests in the manual |
Run the tests as written in the manual rather than from memory — several rely on specific quantities to give a clear result.
What these tests cannot tell you
Being honest about the limits matters as much as the tests:
- Heavy metals — lead, arsenic, cadmium. No home test detects these. Lab only.
- Pesticide residue — invisible to household methods.
- Protein content — you cannot verify a "25 g protein" claim in a kitchen. This needs lab assay.
- Microbial contamination — requires culture testing.
- Amino-acid spiking — the practice of adding cheap nitrogen sources to inflate measured protein is specifically designed to defeat simple testing.
So home tests are a useful first filter for crude adulteration, not a quality guarantee.
How to check a supplement instead
Since protein content cannot be verified at home, judge supplements on process rather than on a kitchen test:
- FSSAI licence number printed on the pack, and a real, verifiable one. This is the legal baseline for food sold in India[2].
- Full nutrition panel with quantities, not a graphic and not "proprietary blend" hiding amounts.
- Ingredient list in order by weight — if a headline superfood appears after the sweetener, there is very little of it.
- Third-party lab testing, ideally published. Brands that test batches for label-claim accuracy and heavy metals are doing the thing home tests cannot.
- Buy from official channels. Counterfeit supplements are a genuine problem in India, and marketplace grey sellers are where they surface.
Where we stand
KABO is manufactured under FSSAI licence with batch testing before release, and publishes its full nutrition panel and ingredient list rather than hiding quantities. We have written the detail in how KABO is made.
That said, apply the checklist above to us as readily as to anyone else — a brand telling you to trust it is worth less than a panel you can read.
If you suspect adulteration
Report it. FSSAI operates consumer grievance channels, and food safety officers act on complaints[2]. If you or a family member becomes unwell after eating a suspect food — persistent vomiting, diarrhoea, or any neurological symptoms — see a doctor first and report afterwards.

Frequently asked questions
How can I check milk adulteration at home?
FSSAI's DART manual gives specific tests: a drop of milk on a slanting polished surface should stay or flow slowly leaving a white trail if pure[1]; iodine turns blue in the presence of starch; and dense persistent lather when shaken with water suggests detergent. Follow the manual's exact quantities for a clear result.
Can I test protein powder for adulteration at home?
Not meaningfully. You cannot verify a protein claim in a kitchen — that needs a lab assay — and amino-acid spiking is specifically designed to defeat simple testing. Judge supplements instead on FSSAI licensing, a fully disclosed nutrition panel with quantities, and published third-party batch testing.
What is the FSSAI DART manual?
It is a free manual published by India's food regulator compiling over 50 rapid tests citizens can perform at home to detect common adulterants in milk, spices, oils, sugar and other foods[1]. It exists specifically to build consumer awareness about food safety.
Which spices are most commonly adulterated in India?
Turmeric and chilli powder are frequent targets — turmeric with lead chromate, which is a genuine health hazard rather than a purity issue, and chilli with brick powder. Ground spices in general can carry sawdust or bran, which floats when sprinkled on water[1].
Do home tests detect heavy metals or pesticides?
No. Home tests catch crude physical and chemical adulteration only. Heavy metals such as lead and arsenic, pesticide residues, microbial contamination and amino-acid spiking all require laboratory testing. This is exactly why third-party lab testing matters for packaged foods and supplements.
