Biomarker Sensing Technology
ZenxTag Technology Limited develops Biomarker Sensing Technology, a low-cost, paper-based smart label system using chemosensing inks to detect spoilage biomarkers (mercaptopans, biogenic amines, ethylene) via visible color changes. This enables real-time, accurate food freshness monitoring, shifting from fixed expiration dates to condition-based assessments to combat global food waste (around 1.3–2.5 billion tonnes annually) and support sustainability.
Special features & Advantages:
- Real-time monitoring with instant visual color indicators (e.g., brown → dark for spoilage in proteins; yellow → purple for over-ripening in fruits).
- High accuracy (70% superior to competitors) and ultra-low cost (<$1 USD per unit, 80% cheaper than lab tests).
- Biomarker-specific detection for targeted freshness signals, unlike time-temperature proxies.
- User-friendly, single-use application: affix to packaging or food surface; check after 30 minutes.
- Seamless integration into supply chains, with IoT potential and specialized containers for daily/gifting use.
Potential application areas:
- Food manufacturing and processing (quality control for meat, seafood, durian).
- Retail and supermarkets (premium fruits like berries/durians for ripeness assurance).
- Hospitality/catering (e.g., hotels like YMCA pilots) to reduce waste and comply with green policies.
- Export/agriculture (minimize spoilage risks in transport).
- Household/consumer use (future versions for home storage).
- Targeting markets in Asia (Hong Kong, Singapore, China), EU, and US, aiming for break-even in 3 years post-funding.
