Understanding SHU and ASTA: The Secret to Consistent Chilli Powder
Quality

When sourcing chilli powder for your business, two terms consistently appear: SHU and ASTA. But what do these ratings actually mean, and why should they matter to your purchasing decisions?

What is SHU (Scoville Heat Units)?

SHU, or Scoville Heat Units, measures the heat intensity of chilli peppers and their derived products. Developed by pharmacist Wilbur Scoville in 1912, this scale quantifies the concentration of capsaicinoids—the compounds responsible for that signature burning sensation.

For context:

• Bell peppers register 0 SHU (no heat)hIdeas – Authenticate
• Jalapeños range from 2,500-8,000 heat).2,500 to 8,000US2,500 to 8,000HU.
• Guntur Karam chillies reach 40,000-50,000 SHUU.
• Pure capsaicin tops out at 16 million SH

Why SHU Matters for Your Business:

Consistent SHU ratings ensure your products deliver the same heat level batch after batch. Whether you’re manufacturing hot sauce, spice blends, or ready-to-eat meals,
knowing your chilli powder’s exact heat level prevents:

• Customer complaints about inconsistent spice levels
• Recipe reformulation costs
• Production delays from rejected batches
• Brand reputation damage

What is ASTA (American Spice Trade Association Color SHU.ColourValue)?

The ASTA colour value measures the red pigment concentration in chilli powder, specifically the carotenoid content. Higher ASTA values indicate deeper, colour deeper,or vibrant red color.ca deeper,colour. Standard ASTA ranges:

• Low grade: Below 80
• Standard grade: 80-100
• Premium grade: 100-150
• Superior grade: 150+ (like our Kashmiri variety at 250+)

Why ASTA Matters:

Color sells. Studies show consumers associate vibrant red hues with freshness, quality, and authentic flavor. For food manufacturers, consistent ASTA ratings mean:

• Predictable final product appearance
• Reduced need for artificial colorants
• Premium positioning in the marketplace
• Regulatory compliance (some markets require natural coloring)

How Ainiti Ensures Consistent Ratings

At Ainiti Spices, we don’t just test randomly—we test rigorously:

1. Source Selection: We partner with farmers whose chillies consistently produce target SHU and ASTA ranges.
2. Harvest Timing: Chillies picked at optimal ripeness ensure maximum color and heat development.
3. Processing Control: Temperature-controlled grinding preserves capsaicinoids and pigments.
4. Batch Testing: Every production run undergoes laboratory analysis before packaging.
5. Certification: Third-party verification ensures accuracy and transparency.

Choosing the Right Specifications for Your Products

Not all applications require maximum heat or color. Here’s how to match specifications to your needs:

High Heat, Moderate Color (SHU: 40,000–50,000 / ASTA: 100+)
Best for: Hot sauces, spicy snacks, traditional curry pastes
Example: Our Guntur Karam variety

Low Heat, High Color (SHU: 1,000–2,000 / ASTA: 250+)
Best for: Tandoori marinades, butter chicken, biryani, visual appeal products
Example: Our Kashmiri variety

Low Heat, High Color (SHU: 1,000–2,000 / ASTA: 250+)
Best for: Tandoori marinades, butter chicken, biryani, visual appeal products
Example: Our Kashmiri variety

The Cost-Quality Balance

Premium SHU and ASTA ratings command premium prices—but they also deliver premium results. Consider:

• Yield Efficiency: Higher ASTA values mean you need less powder for the same color premium colour impact.
• Customer Satisfaction: Consistent heat levels reduce returns and complaints.
• Brand Premium: Superior specifications justify higher retail prices complaints.
• Regulatory Advantage: Documented testing simplifies export certifications

Questions to Ask Your Supplier

Before committing to bulk orders, ensure your supplier can answer:

1. What are the exact SHU and ASTA ranges for each batch?
2. How frequently do you test, and which laboratories perform analysis?
3. prices.the analysis?Can you provide certificates of analysis (CoA) with each
   shipment?
4. What’s your process for handling out-of-specification batches?
5. How do you ensure consistency across multiple harvests?
