Cold-chain monitoring for premium chocolate and gelato

Premium chocolate and gelato are among the least forgiving products in the cold chain. Couverture blooms, texture breaks, and gelato fails after brief excursions outside spec — and in 2026, gelato Listeria recalls across multiple US states showed how costly a cold-chain or quality failure becomes without batch-level traceability.

The invisible loss

Most temperature excursions happen in transit or in a back-of-house freezer and are never recorded. By the time quality drops, the product is already with the customer — and the brand takes the hit.

What TAGUARD changes

• Continuous temperature evidence. TAG K5PT BLE beacons monitor cartons and cold storage and alert before product is ruined.
• Batch-level traceability. When something does go wrong, you isolate the exact affected lots — so recalls are narrower, faster and cheaper.
• Authenticity on the pack. ChaosMark lets shoppers verify genuine premium product and distinguishes it from shelf look-alikes.
