This supplement aims to disseminate results obtained from the fi rst dietary survey carried out in Brazil, in which food records for two non-consecutive days were obtained for each interviewee. The supplement contains six studies which address aspects linked to analyzing the prevalence of consumption of different foods, inadequate intake in different age groups, guidelines for analyzing the sam...

This paper delineates the identity preservation strategy being implemented by the British Retail Consortium and the Food and Drink Federation towards genetically modified foods. The strategy is in direct response to British consumer concerns about genetically modified foods in the wake of the “mad cow” crisis. Consumer needs are being addressed through labeling based on robust global traceabili...

In the last decades, food science has greatly developed, turning from the consideration of food as mere source of energy to a growing awareness on its importance for health and particularly in reducing the risk of diseases. Such vision led to an increasing attention towards the origin and quality of raw materials as well as their derived food products. The continuous advance in molecular biolog...

Many guidelines for safety-critical industries such as aeronautics, medical devices, and railway communications, specify that traceability must be used to demonstrate that a rigorous process has been followed and to provide evidence that the system is safe for use. In practice, there is a gap between what is prescribed by guidelines and what is implemented in practice, making it difficult for o...

With the rise of globalization and technological competition, food supply chain has grown more complex due to multiple players factors involved in chain. Traditional systems fail offer effective reliable traceability solutions considering increasing requirement for accountability transparency Blockchain technology been claimed industry a transformative future. The inherent features blockchain, ...

Agile methodologies represent a set of development processes in which both the requirements and the delivered solution evolve incrementally through a series of short iterations. Such projects are characterized by an emphasis on human interactions and collaborations, lightweight development processes, frequent deliverables, and minimal documentation (Ambler, 2004; Beck and Andres, 2004; Cockburn...

This paper evaluates the effectiveness of an extension to i* modelling – normative i* modelling – during the requirements analysis for new sociotechnical systems for food traceability. The i* focus on modelling systems as networks of heterogeneous, inter-dependent actors provides limited support for modelling system-wide properties and norms, such as laws and regulations, that also influence th...
