Winning entry shows how the company’s patented technology reports real-time product temperature and shelf life status and stores data in secure blockchain records

Oxnard, California – Infratab, Inc. is pleased to announce its case study RFID Tags & Blockchain for the Seafood Cold Chain has been chosen as the top entry in the Blockchain category in AIM’s 2019 Case Study Competition. The winning case study examines Infratab’s project with researchers from the Laboratory of Food Chemistry and Technology, School of Chemical Engineering at the National Technical University of Athens (NTUA) to implement Infratab Freshtime, a condition-intelligent RF sensor blockchain solution, for a fresh fish producer and AB Vassilopoulos, the leading supermarket chain in Greece.

“We’re honored by AIM’s recognition of our work bringing blockchain security to cold chain monitoring” said Therese Myers, CEO of Infratab, “By providing access to perishables’ real-time shelf life status and creating unalterable blockchain records, Freshtime gives producers and retailers the tools they need to reduce product waste and ensure their customers get the quality they expect.”

In the winning case study, the challenge was that the producer and retailer would measure and record the fresh fish’s temperature manually at each step of distribution. If arrival temperature was found to be within the acceptable range, the fish’s shelf-life was assumed to be as expected and no corrective actions were taken. If a fixed expiry date had been exceeded when the fish was received at the supermarket, the fish would be tossed. This cold chain monitoring system, typical in most perishable supply chains, often results in unnecessary food waste or disappointed consumers.

To solve this problem, Infratab and NTUA implemented and tested Infratab Freshtime, a temperature monitoring tag and software solution, to provide real‐time shelf life status to product handlers. The solution utilizes dual RF (RAIN and NFC) temperature and shelf life tags, a mobile smartphone application to handle the tags, and a cloud database for data storage, reporting, analytics, and blockchain updates. The solution’s analytical model (validated by microbiological sampling conducted by NTUA researchers) predicts how much of the fish’s shelf life has been used and how much remains. This information is recorded in blockchain records and reported to handlers via alerts or when the tags are scanned with a mobile app on the handler’s smartphone.

“Infratab’s Freshtime solution provides a powerful monitoring tool assuring a reliable cold chain of highly perishable products,” said Professor Petros S. Taoukis, PhD, NTUA’s lead researcher on the project, “This toolset capitalizes on our kinetic models for shelf life prediction and applies them in the real food chain.”
