Spoilage Marker Dosimetric Tag (SMDT)

ZenxTag Spoilage Marker Dosimetric Tag (SMDT) is a compact smart label (standard size approx. 2 cm x 3.4cm) designed for real-time freshness monitoring of perishable foods such as meats, seafood, and chilled products. Using patented chemosensing ink, it detects mercaptan gases released during protein degradation and changes color progressively to provide a clear visual warning of spoilage before it becomes obvious. To use, simply peel and stick the tag directly onto the packaging (ideally near the product or on a visible area), then monitor the color change at a glance—no equipment required. This eliminates guesswork, reduces food waste and safety risks, enhances consumer confidence, and helps retailers minimize losses. Perfectly fresh, clearly indicated – no guesswork needed.
