Indian Dry Chilli Quality Guide for Importers and Food Industries
Understanding SHU and ASTA in Dry Red Chilli Exports
Understanding the difference between SHU and ASTA helps buyers select the right chilli variety for their applications such as sauces, powders, seasonings, oleoresins, snacks, pickles, and processed foods.
What is SHU in Dry Red Chilli?
SHU Meaning
SHU stands for Scoville Heat Units, which measures the pungency or spiciness of chilli peppers.
The higher the SHU, the hotter the chilli.
This heat comes from a natural compound called:
Capsaicin
Capsaicin concentration determines the spice level of chilli.
Global buyers use SHU values to determine:
- Heat intensity
- Food formulation consistency
- Sauce manufacturing standards
- Spice blend specifications
- Consumer taste preferences
SHU Heat Classification
| SHU Range | Heat Category |
|---|---|
| 0 – 5,000 | Mild |
| 5,000 – 20,000 | Medium |
| 20,000 – 50,000 | Hot |
| 50,000 – 100,000 | Very Hot |
| 100,000+ | Extreme Heat |
ASTA :
- ASTA stands for American Spice Trade Association.
- ASTA value measures the color quality of chilli.
- Higher ASTA means brighter and richer red color
| ASTA Value | Color Quality |
|---|---|
| Below 50 | Low color |
| 50 – 100 | Medium color |
| 100 – 150 | Good export quality |
| 150 – 200 | Premium color |
| 200+ | Very high color chilli |
SHU vs ASTA:
| Parameter | SHU | ASTA |
|---|---|---|
| Full Form | Scoville Heat Units | American Spice Trade Association |

| Related Compound | Capsaicin | Carotenoid Pigments |
| Buyer Focus | Spice Level | Red Color Intensity |
| Used In | Hot sauces, spicy foods | Chilli powder, paprika |
| Higher Value Means | More Heat | Better Color |
Factors Affecting SHU and ASTA in Indian Chillies
Several factors influence chilli quality:
Climate Conditions
Hot weather increases pungency.
Soil Fertility
Healthy soil improves color and yield.
Harvest Timing
Fully mature chillies provide better ASTA values.
Drying Method
Proper sun drying preserves color and heat.
Storage
Incorrect storage reduces ASTA and freshness.
