Need Better Whole-Nut Roast Color Control?

Export buyers notice inconsistencies—do you? Manufacturers often rely on ground samples and handheld chroma meters. This method fails to capture whole-nut appearance. A roast-level measurement that aligns with consumer expectations can elevate product consistency—especially for global export markets.

A slightly over- or under-roasted cashew can affect perceived quality, flavor, and brand trust. Yet many processors still rely on outdated, destructive color checks that don’t reflect what the consumer sees.

Let’s fix that.

Why Color Accuracy Drives Cashew Quality

• Consumer confidence: Global buyers expect golden-brown uniformity. Irregular batches erode trust.
• Export readiness: Color variation is a top rejection reason for U.S. and EU-bound shipments.
• Flavor & texture proxy: Roast color is linked to browning index and sensory qualities.

The Problem with Ground Sample Methods

1. Inaccurate representation: Grinding mixes inner and outer nut layers, masking true surface color.
2. Prep variability: Operator technique affects grind consistency and packing.
3. Low throughput: Each test can take 8–10 minutes—including warm-up, grind, and tray prep.
4. Wasteful: Ground samples can’t be reused—costing time and raw materials.

Meet HunterLab Aeros: True-to-Eye Roast-Level Accuracy

Aeros is the world’s only smart non-contact spectrophotometer engineered for non-homogeneous samples like whole nuts. It delivers fast, objective L* a* b* color values—top-down, without touching the sample.

How It Works:

• Load a tray of whole roasted cashews.
• Aeros scans for color values
• Essentials software delivers instant color analysis that can be exported

Why Processors Are Switching to Aeros:

• ✅ See what your customer sees: Surface color, not internal blend.
• ✅ Results in 5 to 30 seconds: No warm-up, grinding, or prep.
• ✅ No destruction, no waste: Use the same nuts for QA or further testing.
• ✅ Reliable across shifts: HunterLab is renowned for delivering consistent color data repeatedly.
• ✅ Exportable data: Track batch trends, meet buyer specs, and speed up audits.
• ✅ Boost your revenue: Less waste means more profit

Proven Results: Vietnam Cashew Processor

Challenge: Inconsistent roast color and buyer complaints due to ground sample testing using outdated chroma meter.

Solution: Switched to Aeros for whole-nut measurement.

Outcome:

• Reduced standard deviation in L* values from ±3.5 to ±0.8
• Cut sample testing time from 8 minutes to 30 seconds
• Eliminated sample loss and improved cross-shift consistency

“Aeros brought clarity to our roast process. It captured what our eyes saw.”

“We now trust color data across shifts and batches.”

HunterLab’s own research shows spectrophotometers outperform chroma meters for whole, irregular samples. Using L* a* b* values, Aeros supports quality control and export compliance.

Color Science Backed by Standards

HunterLab’s color values align with CIE standards and global export protocols. Unlike cheap handheld tools, Aeros excels with textured, irregular surfaces—delivering repeatable, standardized data across locations and inspectors.
