Food traceability: New trends and recent advances. A review

- Current traceability systems can't provide a consistent information flow.
- New trends are about information management such as FTTO and TraceFood Framework.
- New tech advancements can cover some gaps but still need to become more accessible.
- Traceability centralization and instant access information will become a standard.

Current traceability systems are characterized by the inability to link food chains records, inaccuracy and errors in records and delays in obtaining essential data, which are fundamental in case of food outbreak disease; these systems should address the recall and withdraw of non-consumable products. The present paper provides a review of the various latest technological advancements such as innovative implementations of RFID that can make to increase the sales of wheat flour, or allowing the consumer to know the full record of the IV range products through the smartphone; knowing the food authenticity with an isotope analysis or by analysing the DNA sequences. There are also presented some conceptual advancements in the field of food traceability such as the development of a common framework towards unifying the present technical regulations, the interconnectivity between agents, environment loggers and products, all of them in the form of Internet of things system as well as the development of intelligent traceability, where it is possible to retrieve the temperature of a product or its remaining shelf-life.These new techniques and concepts provide new opportunities for enhancing the efficiency and compatibility of the present traceability systems.
