This article examines deliberative, emotional, and sociocultural processes in consumption. The authors draw upon basic processes from two leading theories in social psychology, the theory of planned behavior (TPB) and the model of goal-directed behavior (MGB), to develop a comprehensive approach to decision making more appropriate for many consumption decisions, and revise the representation and modeling of key variables to better reflect how social psychological processes relate to consumer behavior. A survey was conducted among real adult consumers of bacalhau in Portugal. Because it is most common for women to prepare bacalhau meals in Portugal, 153 female participants were recruited for this survey. The results show that the TPB, and especially the MGB, are found to explain food consumption decisions well but only after the approaches are modified in form and content to accommodate the complex emotional and social aspects of the consumption context. The results also show that the effects of key determinants of desire in the MGB are contingent on the traits of food involvement and cultural orientation (i.e., degree of vertical individualism). The approach taken herein overcomes limitations of existing theories by synthesizing relevant processes across two leading theories and by introducing new variables and processes, thereby showing that the organization of these processes and their contingency on cultural variables regulate consumption. © 2012 Wiley Periodicals, Inc.

The aims of this study were to investigate effects of dietary mineral supplementation on chemical and sensory quality parameters of fresh farmed cod fillets and on the quality of salt-cured farmed cod. Farmed cod were fed three experimental diets with different levels of mineral supplements (no supplementation, supplementation without zinc and copper, full supplementation) for approximately 2 yr. After slaughter, one-third of the experimental fish were subjected to chemical and physical analysis, another third were used for sensory analysis and the remaining fish were salt cured. Potassium, copper, and muscle protein were higher in muscle tissue of cod fed full supplementation than cod fed without supplementation. Instrumental color analysis showed that the cut side of fresh fillets of cod fed full supplementation were slightly more green and yellow than fillets of cod fed without extra supplements. A sensory panel could, however, not detect any differences between heated fresh cod given feed with or without mineral supplements. However, the quality of salt ripened cod which had received a complete mineral supplement in the diet was reduced because of increased yellowness, probably caused by the increased level of copper in the muscle. © Copyright by the World Aquaculture Society 2011.

Purpose - The purpose of this study is to examine where product, process and traceability information is systematically lost at a mineral water bottling plant. It aims to highlight areas where traceability could be improved and to suggest changes that could be made to improve traceability. It also aims to examine the implications of these changes for the current system. Design/methodology/approach - Process mapping was carried out at a mineral water bottling plant to investigate the flow of material and information. The results were analyzed to identify the critical traceability points (CTPs) in the production process where information is lost. Findings - One of the CTPs at the mineral water bottling plant was the lack of a link between product, process and traceability information for the screw caps. Research limitations/implications - This is a study of an individual case, which limits the generalizations that can be made. Practical implications - Procedures need to be established at the mineral water bottling plant in order to achieve traceability. All the information about the resources used in production could be linked to a "best before" date on each mineral water bottle. Originality/value - The authors have found few similar case studies in the published literature. This case study can be of value to other research institutes and industries where the focus is on traceability. It could also be of interest to researchers working with information technology systems, ontology/metadata schemes, cost/benefits analyses and the impacts of traceability. The implications of traceability highlighted in this paper can be of use to regulatory authorities in their decision making processes. © Emerald Group Publishing Limited.
