Using FoodSense Gen 4 to Analyse “Breath of the Dragon” 🌶️
Retail hot sauces often come with dramatic names—“Breath of the Dragon”, “Inferno Blaze”, “Ultimate Fire”. But how hot are they really?
In my latest test, I walked through a full end‑to‑end Scoville Heat Unit (SHU) measurement using the FoodSense Generation 4 system. Here’s what happened 👇
🔬 1. Sample Prep: The Most Important Part
Retail sauces are typically mild, so dilution is key.
Started with 100 µL of sauce + 900 µL of buffer
Vortex mixed to quickly extract capsaicin
Applied the sample to a fresh chili sensor
Most of the effort is in preparing a clean, accurate sample—testing itself is fast.
📱 2. Smart Feedback from the App
The first run returned: “Too dilute – dilute less.”
No surprise for mild retail sauces!
So I added another 100 µL of sauce into the same dilution tube, effectively creating a 1‑in‑5 dilution, vortexed again, and re-ran the test with a new sensor.
⚡ 3. Fast Test, Cloud Analysis
Each FoodSense run takes around 13 seconds.
The data is:
captured in real-time
uploaded to the cloud
analysed automatically
then returned to the app and also stored in Djuli for deeper inspection
📊 4. The Result: 364 SHU
The “Breath of the Dragon” sauce came in at 364 Scoville Heat Units.
To put that into perspective:
It’s very mild
Far below the threshold where manufacturers would need strong warning labels
Below the detection range of HPLC, which typically can’t accurately quantify capsaicin below ~750 SHU
Interestingly, having bought a multipack, I suspect many of the sauces are actually the same base blend with minor flavour tweaks!
📁 5. Why Djuli Matters
Beyond just giving a heat number, Djuli lets you view:
Raw electrochemical peaks
Peak 1, 2, and 3 capsaicin signals
Full analysis trace
Export options (PDF, Excel, etc.)
This provides transparency and confidence that automated results match real signal quality.
✅ Summary
FoodSense Gen 4 is:
Fast
Easy to use
Sensitive (far more than HPLC for mild products!!)
Backed by real-time cloud analytics
Ideal for QA teams, producers, or hot sauce makers who need rapid SHU measurements
