Amchur (Dry Mango Powder)
Sourness with function. Amchur adds vitamin C and tartaric acid to dishes — doubling iron absorption from the same meal.
TLDR — Amchur
- Amchur is made from dried, unripe (green) mangoes — hence the intense sourness from high tartaric and citric acid
- Vitamin C survives partial drying — amchur retains meaningful Vitamin C that enhances non-haem iron absorption
- Adding amchur to dal or iron-rich vegetables significantly increases how much iron your body absorbs
- Amchur is a souring agent that also acts as a meat tenderiser — the acids partially denature proteins
- Potassium content (1600mg/100g) contributes to blood pressure management at cooking doses
- Traditional North Indian seasoning in chaat, chole, dal makhani, and vegetable stir-fries
What Is Amchur?
Amchur (also spelled amchoor) is made by slicing unripe green mangoes, sun-drying them, and grinding to a pale tan powder. The unripe mango is used specifically because of its high tartaric acid and citric acid content — which concentrates during drying to give amchur its characteristic sharp, sour taste.
The key nutritional distinction from ripe mango: unripe mango has higher tartaric acid and Vitamin C (which decreases as mango ripens). Drying preserves a significant portion of this.

The Iron Absorption Story
This is the primary health benefit of amchur in an Indian diet context. Non-haem iron (from dal, spinach, fenugreek) has low absorption — typically 3–8%. Vitamin C and organic acids (tartaric, citric) dramatically increase this:
- Adding Vitamin C to an iron-rich meal increases non-haem iron absorption by 50–300%
- Even 25–50mg Vitamin C doubles iron absorption
- Amchur provides organic acids AND Vitamin C — both mechanisms simultaneously
Practical implication: Adding 1/2 tsp amchur to dal, spinach curry, or rajma significantly increases the iron you actually absorb from that meal. This is especially important for vegetarians who rely on plant iron sources.
Amchur vs Other Souring Agents
Amchur vs Other Souring Agents
| Souring Agent | Primary Acid | Vitamin C | Flavour Profile | Best Use |
|---|---|---|---|---|
| Amchur | Tartaric + citric | Yes (~40–70mg/100g) | Fruity-sour, slightly sweet | Dal, chaat, dry vegetables, marinades |
| Tamarind (imli) | Tartaric acid | Trace | Deep, sweet-sour, complex | Rasam, sambar, chutneys, puliyogare |
| Lemon/lime juice | Citric acid | Very high | Bright, fresh | Finishing, chutneys, marinades |
| Kokum | Hydroxycitric acid | Some | Deep sour, slightly bitter | Coastal Karnataka/Goa curries, sol kadhi |
| Tomato | Citric + malic | Some | Mild sour, sweet | Base for curries, gravies |
Amchur's tartaric acid is more stable to heat than Vitamin C — it retains sourness through long cooking better than lemon juice.
How to Use Amchur
In cooking:
- Add 1/2–1 tsp amchur to dal (along with the tadka, at the end) for souring without tamarind
- Toss 1/2 tsp over roasted vegetables or aloo for a chaat-style finishing
- Add to chole, rajma, and other legume dishes for sourness and iron absorption boost
- Use in marinades for chicken, paneer, or vegetables — the acids tenderise proteins
When NOT to use:
- Do not substitute amchur for lemon juice in salads or raw preparations — it lacks the brightness of fresh citrus
- Amchur turns grey-brown in colour when added to dairy — use tamarind or lemon instead for curd-based dishes
Home Test: Quality and Purity Test for Amchur
Steps
- 1 Observe colour — should be pale tan to light brown, not bright yellow or orange
- 2 Dissolve 1/2 tsp in water and taste
- 3 Smell the powder — should have a mango-fruity, sour aroma
Pure / Pass
Pale tan colour. Strongly sour taste in water with a faint mango fruitiness. Mild mango-citrus aroma.
Adulterated / Fail
Bright yellow or orange colour may indicate added colour (artificial colouring). Very weak sourness suggests starch dilution. Absence of any mango fruitiness suggests non-mango adulterant used for sourness.

Frequently Asked Questions
Q Can amchur help with iron deficiency anaemia?
Can amchur help with iron deficiency anaemia?
Yes, as a supportive dietary measure. Adding amchur (and other vitamin C sources) to iron-rich meals like dal, spinach, and rajma significantly increases non-haem iron absorption. A 1/2 tsp of amchur contains enough Vitamin C and organic acids to noticeably increase the iron absorbed from that meal. It should be part of an overall dietary strategy for anaemia alongside medical treatment.
Q Is amchur acidic enough to replace tamarind?
Is amchur acidic enough to replace tamarind?
The sourness comes from different acids. Amchur is sour and fruity; tamarind is deeper and more complex with its own characteristic flavour. They are not direct substitutes in taste terms, though both are souring agents. Amchur works better in dry dishes and North Indian cooking; tamarind is essential for authentic South Indian rasam and sambar.
Q How is amchur stored?
How is amchur stored?
In an airtight container in a cool, dry place. Amchur is hygroscopic — it absorbs moisture readily. If it clumps, it has absorbed humidity and quality may have declined. A small silica gel packet in the container helps. Properly stored amchur lasts 12–18 months.
Q Can diabetics use amchur?
Can diabetics use amchur?
Yes — amchur has a low glycaemic impact due to its high acid content (acids slow starch digestion) and low sugar content compared to fresh mango. The tartaric acid may modestly improve post-meal glucose response. It is a suitable souring agent for diabetic cooking as a substitute for tamarind or sugar in some recipes.
