Chilli Powder
India's most adulterated spice — and one of its most nutritious. Capsaicin, Vitamin C, and how to tell Byadgi from Guntur.
TLDR — Chilli Powder
- Red chilli powder is one of the highest Vitamin C foods when fresh — 142mg/100g in dried chilli
- Capsaicin provides anti-inflammatory, pain-relief, and metabolism-boosting effects at realistic dietary doses
- Byadgi chilli (Karnataka) — deep colour, mild heat, high colour pigment. Guntur (Andhra) — fiery heat, high capsaicin
- FSSAI data: chilli powder is the most adulterated spice in India — artificial colours, brick powder, sawdust
- The water test detects most adulterants — pure chilli sinks, artificial colour disperses immediately
- Capsaicin is fat-soluble — that is why milk (not water) relieves chilli heat burning
What Is Chilli Powder?
Red chilli powder is made from dried and ground red chillies (Capsicum annuum and Capsicum frutescens). India is the world’s largest producer, consumer, and exporter of chillies — over 1.5 million tonnes annually. Different chilli varieties produce very different powders in terms of heat, colour, and flavour.
The active compound is capsaicin — the alkaloid responsible for heat, anti-inflammatory effects, and the thermogenic metabolism boost. Heat intensity is measured in Scoville Heat Units (SHU).

Byadgi vs Guntur — India’s Two Major Chilli Varieties
Byadgi vs Guntur Chilli Powder
| Parameter | Byadgi (Karnataka) | Guntur (Andhra Pradesh) |
|---|---|---|
| Heat level (SHU) | 10,000–20,000 (mild) | 30,000–100,000+ (fiery) |
| Colour | Deep, dark blood-red — premium colour | Bright orange-red — high capsaicin |
| Colour pigment (ASTA) | 150–200 (highest in world) | 90–120 |
| Primary use | Colour-focused dishes, curries, masalas | Heat-forward dishes, spicy gravies |
| Capsaicin content | Low — mild on palate | High — intense heat |
| Karnataka dishes | Bisi bele bath, saaru, coastal curries | Less traditional |
| Export premium | High — paprika substitute globally | Standard export chilli |
Byadgi is prized for colour; Guntur for heat. Most commercial chilli powders blend varieties. Organic Mandya's chilli powder is Byadgi-dominant.
Health Benefits of Capsaicin
1. Anti-inflammatory Capsaicin inhibits Substance P (the primary pain neurotransmitter) and reduces NF-κB inflammatory signalling. Multiple clinical studies confirm topical capsaicin reduces arthritis and nerve pain. Dietary capsaicin at cooking quantities provides milder but real anti-inflammatory benefit.
2. Metabolism boost Capsaicin activates TRPV1 receptors in adipose tissue, increasing thermogenesis. Meta-analyses show approximately 4% increase in metabolic rate from dietary capsaicin — modest but real. Used in weight management research as a non-stimulant thermogenic.
3. Cardiovascular Observational studies (including large Chinese cohort studies) find consistent association between regular chilli consumption and lower cardiovascular mortality. Capsaicin may reduce LDL oxidation and platelet aggregation.
4. Gut microbiome Capsaicin has antimicrobial activity against H. pylori at high concentrations. Moderate chilli consumption supports gut microbial diversity in observational studies.
Side Effects — Who Should Limit
- GERD/acid reflux: Capsaicin relaxes the lower oesophageal sphincter — worsens reflux. Reduce or eliminate in active GERD.
- Irritable bowel syndrome (IBS): Activates TRPV1 in colon mucosa — can trigger cramping and urgency.
- Piles/haemorrhoids: Capsaicin excreted in stool causes burning around inflamed tissue.
- Peptic ulcer: Contrary to old belief, moderate chilli does not cause ulcers — but may worsen existing ones.
- Infants and young children: No chilli before 2 years. Introduce gradually after that.
Adulteration — The Most Tested Spice in India
Chilli powder is FSSAI’s highest-risk category for adulteration. Common adulterants:
- Artificial colours: Sudan Red, Rhodamine B (carcinogenic) — added to enhance appearance
- Brick powder/sawdust: Added for weight
- Corn starch/rice flour: Bulks out the powder
Home Test: Water Test for Artificial Colour in Chilli Powder
Steps
- 1 Add 1/2 tsp chilli powder to a glass of room-temperature water
- 2 Do NOT stir — observe what happens in the first 30 seconds
- 3 Then stir gently and observe the water colour
Pure / Pass
Natural chilli powder sinks slowly. Water acquires a light orange-red tinge after stirring — the natural pigments gradually dissolve. Colour is soft, not garish.
Adulterated / Fail
Artificial colour disperses immediately and dramatically into the water before stirring — produces vivid red/orange streaks. Water turns intensely coloured within 10 seconds. This indicates added dye. Organic-certified, lab-tested chilli will not show this reaction.

Frequently Asked Questions
Q Is red chilli powder good or bad for health?
Is red chilli powder good or bad for health?
At typical Indian cooking quantities (1/4–1/2 tsp per meal), red chilli powder is beneficial — anti-inflammatory, metabolism-supporting, and rich in carotenoids and Vitamin C. Problems arise at excessive intake (>2 tsp/day) or in people with GERD, IBS, or existing GI conditions. For most healthy adults, daily cooking use is fine and beneficial.
Q How do I know if my chilli powder is adulterated?
How do I know if my chilli powder is adulterated?
The water test is the simplest: drop 1/2 tsp in water without stirring. Pure chilli sinks; artificial colour immediately disperses in vivid streaks. Lab testing (like Organic Mandya's third-party NABL reports) is the definitive method — checks for Sudan Red, Rhodamine B, and other carcinogenic dyes.
Q Byadgi or Guntur — which should I use?
Byadgi or Guntur — which should I use?
Use both for different purposes. Byadgi for dishes where colour matters (South Indian curries, masalas) — it gives the characteristic deep red without overwhelming heat. Guntur when you want actual heat. Most home cooks blend 2 parts Byadgi to 1 part Guntur for balanced colour and heat.
Q Does chilli powder cause ulcers?
Does chilli powder cause ulcers?
No — this is a persistent myth. Moderate chilli consumption does not cause peptic ulcers (H. pylori is the primary cause). However, if you already have an ulcer, capsaicin may worsen symptoms. The old medical advice to avoid chilli for ulcer prevention was not evidence-based.
Q Why does milk cool chilli heat but water doesn't?
Why does milk cool chilli heat but water doesn't?
Capsaicin is fat-soluble, not water-soluble. Water moves capsaicin around your mouth without dissolving it — often spreading the burn. Milk contains casein protein and fat, both of which bind capsaicin and remove it from the TRPV1 receptors. Ghee, yogurt, or full-fat milk are the most effective heat relievers.
