A quick, practical demonstration using a retail hot sauce
In this short demonstration, we put a retail hot sauce to the test using FoodSense Generation 4, our latest solution for measuring chilli heat accurately and transparently.
Hot sauces often come wrapped in dramatic branding—skulls, warning labels, and “death-tier” claims—but how hot are they really? Rather than relying on marketing or vague Scoville claims, this video shows how FoodSense Gen 4 measures actual Scoville Heat Units (SHU) using a repeatable, data-driven process.
The sample: a retail hot sauce
The sauce tested is a readily available retail product, not something from a specialist chilli boutique. Based on taste alone, expectations were modest: vinegary, not especially viscous, and noticeably milder than extreme sauces known for six-figure SHU ratings.
This makes it a perfect example of why analytical measurement matters—retail products often look intimidating but may deliver far less heat than their packaging suggests.
Sample preparation and dilution
To begin, a small amount of the sauce is transferred into a beaker. The sauce is relatively fluid, slightly thicker than something like Tabasco, so minimal preparation is required.
The measurement follows a 1-in-10 dilution protocol:
100 µL of hot sauce
900 µL of FoodSense chilli buffer
The chilli buffer is supplied with the FoodSense Generation 4 system and ensures consistent, reproducible results. While vortexing isn’t strictly necessary for liquid samples like this, a brief mix helps ensure uniformity—especially useful for thicker or powder-based products.
Sensor setup and measurement
A fresh chilli sensor is snapped into place on the FoodSense Generation 4 device. The diluted sample is then applied, and measurement is started via a Bluetooth-connected smartphone.
The mobile app allows you to:
Name the sample
Select the dilution factor
Start the analysis instantly
During measurement, distinct capsaicin peaks are detected and analysed. These peaks are what the system uses to calculate the Scoville Heat Units with precision.
The result: mild by design
The final reading for this sauce came out at 914 Scoville Heat Units.
In practical terms, this places the sauce firmly in the mild category—far from the intense heat levels associated with products like Da Bomb, which can reach hundreds of thousands of SHU.
This result aligns perfectly with the tasting experience and reinforces an important point: dramatic labelling does not always equal extreme heat.
Full traceability via the cloud
One of the most powerful aspects of FoodSense Generation 4 is data transparency. Every test is automatically uploaded to the cloud, where users can:
Inspect individual capsaicin peaks
Verify how the final SHU value was calculated
This is especially important in the food and beverage industry, where Scoville values are often shared as single numbers on certificates of analysis, with little insight into how they were derived. FoodSense changes that by giving full visibility and traceability.
Why this matters
Accurate heat measurement isn’t just about curiosity—it’s about:
Consumer safety
Regulatory compliance
Product consistency
Trust in labelling
Overstating chilli heat can be misleading at best and harmful at worst. FoodSense Gen 4 provides an efficient, repeatable way to measure chilli heat properly, whether you’re testing sauces, powders, or raw ingredients.
Final thoughts
This quick demonstration shows just how easy it is to measure Scoville Heat Units with FoodSense Generation 4—and why many retail hot sauces turn out to be far milder than their branding suggests.
