Current status and future trends of monitoring technologies for food products traceability

摘要

This paper presents the current status and future trends of sensor technologies for food productstraceability, specifically for systems devoted to be applied in the cold storage and refrigeratedtransport of horticultural products. The available monitoring technologies such as dataloggers, TTI,WSN, RFID, and combined approaches are evaluated and compared in terms of dimensions, sensorparameter (temperature, relative humidity, water vapor, ethylene and other gases released duringthe biological processes of fruit), robustness, reliability, energy autonomy, bandwidth (if applicable),connection, among others. The aim of the study consists in evaluating how these technologies canbe successfully applied for traceability of horticultural products and are what the future trends interms of technical and technological specifications that will guide the development of these systems.It is expected that the increasing use of these systems for food traceability increases food qualityand safety, reducing food waste.
