Detecting the caffeine in coffee and decaffeinated coffee

FoodSense analytical system. In this session, we analyze:

Red Bull Energy Drink

Regular Instant Coffee

Decaffeinated Coffee

Key Highlights of the Demonstration:

✅ Efficient Testing Process – The FoodSense meter, paired with its dedicated app, delivers rapid and accurate results via Bluetooth connectivity.

✅ Multi-Analyte Capability – Beyond caffeine, FoodSense can measure various analytes, including chili heat (Scoville units), ginger pungency, and even safety markers like lead and copper in water.

✅ Step-by-Step Sample Prep – Watch as we prepare and test each sample:

Red Bull: Direct measurement with proprietary buffer (50 µL sample + 50 µL buffer).

Coffee & Decaf: Prepared at industry-standard ratios (0.21g in 25mL boiling water) before testing.

✅ Cloud-Based Data Management – All results are automatically uploaded to Djuli, our secure cloud platform, enabling full traceability, exportable reports, and API integration for electronic record-keeping.

✅ Real-Time Results & Verification –

Red Bull: Confirmed at 0.3 mg/g, matching labeled values.

Regular Coffee: Detected at ~0.2 mg/g.

Decaf: Validated as caffeine-free, with clear signal differences shown in comparative analysis.
