Turmeric Powder — Quick Screen for Artificial Colour

What FSSAI's water screen is looking for

FSSAI's consumer video and Eat Right materials demonstrate a simple turmeric check using water. Pure turmeric can naturally give water a light yellow tint. The warning sign is a strong, rapid, artificial-looking release of colour. Kitchen Check should therefore compare intensity and speed cautiously instead of treating any yellow water as adulteration.

Use water only

Do not add hydrochloric acid, sulfuric acid, bleach or another chemical after the water check. FSSAI laboratory methods for identifying specific colours or contaminants may use hazardous reagents, but that is a different level of testing. The consumer card should remain a plain-water screen.

Natural turmeric varies

Colour can differ with turmeric variety, curcumin level, processing, storage and grind size. One genuine turmeric powder may look deeper yellow than another. That is why a single photo comparison is not enough to prove adulteration. The app should use 'suspicious colour release' rather than 'fake turmeric'.

Lead chromate cannot be confirmed with this screen

FSSAI guidance lists lead chromate among possible turmeric adulterants, but the plain-water test does not identify lead. A strong yellow colour is not evidence that lead chromate is present. This distinction is essential because users may otherwise interpret a harmless colour observation as proof of heavy-metal contamination.

Check the pack and purchase source

FSSAI advises avoiding ground spices sold loose and prefers packaged, traceable products. If the turmeric screen is suspicious, keep the original pack, batch number, packed date and seller information. This supports a proper complaint better than repeatedly treating the sample with different household substances.

Test only a small portion

Use a small spoonful and keep the main package uncontaminated. Do not pour the tested wet turmeric back into the pack. If official testing later becomes necessary, the remaining dry sample is more useful. This rule should be standard across Kitchen Check.

Recommended result wording

Use 'No unusually strong colour release seen', 'Unclear—natural colour may be affecting the result', or 'Strong rapid colour release seen—screen suspicious'. The card should never say which dye is present unless a validated confirmatory method has actually identified it.

Do not use phone-camera colour scoring as proof

Lighting, camera settings, glass colour and screen brightness can all change how yellow the water appears in a photo. Kitchen Check can let the user save a reference photo for their own record, but it should not calculate a numerical purity score from the image. The FSSAI rapid method is a visual consumer screen, not a validated phone-based colour measurement system.

A photo can document, not confirm.
