Food Grains — Quick Screen for Added Colour

What this rapid screen is checking

FSSAI consumer guidance includes a simple water-based check for colour added to food grains. A small grain sample is mixed thoroughly in a transparent glass of water. If the water remains essentially unchanged, the rapid screen does not show obvious colour release. If the water changes colour immediately, the sample can be marked as suspicious. This is a quick awareness check, not a legal finding.

Use only plain water

Do not add acid, detergent, bleach, lemon juice or another household chemical to make the result stronger. The value of this check is that it is simple and low risk. A clean transparent glass makes colour easier to see. If the water itself is coloured or the glass has residue, the test becomes harder to interpret.

Natural dust can confuse the result

Grains may carry normal dust, bran particles or surface material that makes water slightly cloudy. Cloudiness is not the same as a strong artificial colour release. Kitchen Check should therefore ask the user whether the water became distinctly coloured rather than simply less clear. A faint natural tint should be labelled 'unclear' rather than automatically failing the sample.

This test does not identify a specific dye

Even when obvious colour leaves the grain, this test does not tell which dye is present. Some dye identification methods use acids or laboratory reagents and should not be added casually to a household workflow. The app should stop at 'colour release suspicious' and move to official confirmation if the issue matters.

Check the product context

Read the package and product name before assuming hidden colouring. Some processed grain products may legally contain declared ingredients or colours, while plain staple grains generally should match their standard. The app should distinguish a declared processed product from an undeclared colour concern. Keep the label, batch and purchase source if you may report it.

Do not wash away the evidence

If one small test portion looks suspicious, do not rinse or soak the entire remaining product repeatedly. Keep most of the product untouched in the original container where possible. This is useful if official testing or a complaint follows. Kitchen Check should always use a small portion for screening and preserve the main sample.

Recommended result wording

Use one of three labels: 'No obvious added-colour release in this rapid screen', 'Unclear—repeat once with a clean glass and fresh water', or 'Immediate colour release seen—screen suspicious; consider official confirmation'. Never show '100% pure grain' from this one test.

Keep comparison conditions simple

If you repeat this screen, use the same type of glass, similar water volume and a fresh sample from the same pack. Do not compare one result made with warm water against another made with cold water and then treat the difference as proof. Kitchen Check should guide users to repeat only once when unclear. Repeated testing until a desired answer appears creates false confidence and wastes the sample.
