Zarda Rang Food Colour: Permitted vs Banned Dyes and Safer Swaps

Warning first, recipe second. The small unlabelled twist of orange or yellow powder sold loose in many markets for zarda, jalebi and biryani can contain dyes that were never meant for food. What looks like harmless zarda rang is the one kitchen shortcut worth changing.

What zarda rang actually is

“Zarda rang” or “khane ka rang” is a synthetic food colour powder, usually orange, yellow, red or green. It’s used for zarda (sweet saffron-coloured rice), biryani layers, jalebi, mithai, tikka and pakoray. A tiny amount gives a vivid colour that saffron or haldi can’t match at the same price.

There are two very different things sold under that name.

Permitted food colours

These are permitted in food within set limits in many countries, though the exact list differs from country to country. Common ones include tartrazine (E102, yellow), sunset yellow (E110, orange), carmoisine (E122, red), ponceau 4R (E124, red) and allura red (E129). They come in sealed, labelled packs naming the colour and E number.

Non-permitted colours

These are industrial dyes for textiles, paper or leather. The ones food safety officials in South Asia keep finding in loose sweets and colours include metanil yellow, auramine, rhodamine B (a pink-red) and Sudan dyes. They’re banned in food because of toxicity concerns, including possible harm to the liver and nerves and cancer risk with some. They’re used because they’re cheap and very bright.

You can’t tell which is which by looking, and a loose, unlabelled powder in a paper twist could be either one. Nobody can.

How little food colour you actually need

Most home cooks use far too much, because the powder looks so harmless in the spoon and food colour is far stronger than people expect. More doesn’t make zarda more yellow after a point; it makes it look artificial and leaves orange stains on hands and plates.

1. Dissolve colour first, never sprinkle dry. Dry specks give dark spots.
2. For zarda from 500 g rice: dissolve ⅛ tsp yellow or orange colour in 2 tbsp warm milk or water. Add to the boiling rice water. Many cooks use half of that and are happy.
3. For biryani (1 kg rice): dissolve a small pinch (under ⅛ tsp) in 3 tbsp milk, and drizzle over only part of the top layer for the classic white, yellow and orange grains.
4. For jalebi batter or tikka marinade: 2 or 3 grains on the tip of a knife, dissolved in 1 tsp water, is often enough for a family batch.
5. Wash hands, bowls and spoons straight after; it stains wooden spoons and marble counters.

Liquid colours sold in dropper bottles are easier to dose: start with 2 to 3 drops for 500 g rice.

Safer swaps: saffron and haldi

Saffron (zafran)

The traditional choice for zarda and shahi biryani. It gives a golden yellow and a honey-floral smell, not neon orange. For 500 g rice, soak a generous pinch (about 20 to 25 threads) in 3 tbsp warm milk for at least 20 minutes, pressing the threads with a spoon. Saffron is also faked, with dyed corn silk and safflower common. Our zafran guide covers testing and soaking in full.

Haldi (turmeric)

Cheap, fully natural, and gives real yellow. The catch is flavour and a quirk of chemistry: haldi turns reddish brown in anything alkaline. For zarda, use only ¼ tsp for 500 g rice in the boiling water; more and the rice tastes earthy. Don’t use it in batter with baking soda, where it goes rusty. Haldi is also an adulteration target itself; see our haldi guide for buying.

Other options

• Kashmiri mirch for red tikka colour without dye (1 to 2 tsp per 1 kg meat)
• Paprika extract (E160c) or beetroot powder for red in sweets
• No colour at all. A pale zarda made with good ghee, cardamom and nuts tastes exactly the same.

Food colours and children

Children eat most of the brightly coloured foods: jalebi, laddoo, candy, coloured drinks, birthday cake and ice lollies. They’re also smaller, so the same amount of colour is a bigger dose for their body weight.

In the European Union, foods containing six of the common synthetic colours (including tartrazine, sunset yellow, carmoisine, ponceau 4R and allura red) must carry a warning that they may affect activity and attention in children. That’s a precautionary label, not proof of harm to every child, but it’s a reasonable reason for parents to keep coloured foods occasional.

Practical steps: choose uncoloured mithai where you can, make birthday treats with saffron or no colour, and never use loose unlabelled colour in anything a child will eat.

Spotting risky colour in sweets and ready food

There’s no reliable home test for non-permitted dyes. What you can do:

• Be wary of colours that look fluorescent or glow, especially shocking pink or lemon yellow in loose sweets.
• Notice if colour runs heavily onto your fingers and doesn’t wash off easily.
• Prefer shops with labelled packaging and a food licence displayed.
• Buy colour from grocery shelves in sealed packs, not from the loose spice counter.

Storing and labelling colour at home

Once opened, fold the colour pack tightly and keep it inside a small labelled jar, on a high shelf. Moisture turns the powder into hard, blotchy lumps that are easy to overdose, because people scrape off a chunk. If a pack has lost its label, don’t guess what it is; throw it out. And never decant colour into an old spice jar where someone might mistake it for haldi or lal mirch.
