How a Global Food Manufacturer Went Paperless and Gained Real-Time Colour Insight
Kellogg’s, the multinational food giant behind Cheez-It®, made a decisive move to digitize its quality control processes. Their goal: eliminate paper-based documentation and install a real-time colour monitoring solution for snack production lines.
To achieve this, they partnered with HunterLab, the trusted name in colour science for over 70 years.

The Challenge: A Need for Real-Time, Reliable Colour Data
Cheez-It®'s distinctive golden hue is iconic—but achieving that consistency at scale required more than visual inspection and manual records. Lab-based methods slowed down decision-making and left quality teams reacting to problems after the fact.
Kellogg’s needed an in-line solution to:
- Deliver real-time colour data
- Replace paper logs with digital records
- Improve accuracy and operator response time
- Support continuous improvement initiatives
The Solution: SpectraTrend HT In-Process Colour Measurement
HunterLab recommended SpectraTrend HT, the premier in-line spectrophotometer built for high-speed food manufacturing. It enables non-contact, continuous colour monitoring—delivering instant feedback during production.
Why it works:
- 📏 Measures colour in real time using CIE Lab* values
- 💾 Digitally records every reading—no manual logging
- 🔧 Allows operators to make immediate adjustments
- 🧠 Integrates with existing MES and QA systems
The Trial: Turning Data into Confidence
Kellogg’s conducted a weeks-long trial at one of its Cheez-It® facilities, installing SpectraTrend HT to run alongside existing lab tech. The team compared readings in real-time and reviewed logged data across batches.
The outcome? SpectraTrend HT proved its accuracy matched the lab—and delivered results faster, cleaner, and with fewer errors.
Going Paperless with Purpose
With SpectraTrend HT, Kellogg’s eliminated manual documentation. Operators could now view live dashboards showing colour trends, alerts, and statistical process control—all without jotting down a single number on paper.
The shift to digital also brought more visibility across teams and supported Kellogg’s sustainability goals by reducing waste.
The Results: Measurable, Scalable Impact
Post-trial, the results were clear—and impressive:
- ✅ 80% faster detection of colour deviations
- ✅ 10% boost in first-pass yield
- ✅ 100% elimination of paper logs
- ✅ Improved sustainability metrics from reduced scrap
The pilot plant commissioned SpectraTrend HT for full production—and plans are underway to expand across Kellogg’s network.
