We combined the most relevant variables from the principal agent theory and the technology acceptance model to develop a parsimonious model of technology acceptance for food traceability systems, which are voluntary, direct consumer-use decision support systems that reduce health risks for consumers by reducing information asymmetry between consumers and sellers in retail settings. Results from...

Environmental concerns about the scarcity of marine resources are critical driving forces for firms aiming to prepare their supply chains for sustainability. Building on previous work, this paper highlights the implementation of good practices geared towards sustainable operations in the seafood department, which were pursued in an exploratory retailer case. Outcomes of the adopted environmenta...

Background Hazelnut is one of the most largely consumed tree nuts, which is used in a wide range of processed foods. However, it is classified as a potential allergenic ingredient and, consequently, should be declared in the label of pre-packaged foods (Directive 2007/68/EC), independently of its amounts. To verify the compliance with labelling and to safeguard the health of sensitised individu...

At present, blockchain technology is more and widely used in the field of food traceability, good results have been achieved. However, many current technologies algorithms are not developed for specific situation resulting resource waste low computational efficiency. In view these problems, this paper analyzes summarizes classic distributed consensus mechanism technology, focusing on PBFT (prac...

Sometimes authorities are unable to identify rapidly the origin of a tainted product. In such cases, recalls or warnings are often applied to all suppliers, which means that the recall applies to suppliers of products that had not contributed to the contamination. One benefit of traceability is to enable more targeted recalls, identifying more specifically the product’s origin. In this article,...

Traceability through physical labels is well established, but it is not highly reliable as physical labels can be easily changed or lost. Application of DNA markers to the traceability of food plays an increasingly important role for consumer protection and confidence building. In this study, we tested the efficiency of 16 polymorphic microsatellites and their combinations for tracing 368 fish ...

In today’s competitive economic environment, track and trace (the capability to determine present and past locations of products through the whole supply chain) is becoming an increasingly urgent necessity and a key differentiator in many industries, enhancing pilferage reduction, counterfeit prevention and targeted recalls, and improving supply chain efficiency, synchronization, visibility, an...

An interesting research problem in our age of Big Data is that of determining provenance. Granular evaluation of provenance of physical goods--e.g. tracking ingredients of a pharmaceutical or demonstrating authenticity of luxury goods--has often not been possible with today's items that are produced and transported in complex, inter-organizational, often internationally-spanning supply chains. ...
