    This thesis highlights consumer perceptions of brewer’s spent grain (BSG) in food products. BSG is a by-product of beer production that has good potential to be used in food products because of its high nutritional value. It is a readily available and sustainable ingredient, but it is underexploited in food production due to some challenges it faces, including poor technological quality, logistics and easy spoilage. The subject of this thesis aligns with the scope of United Nations Sustainable Development Goals: one of the targets is to halve food waste by 2030 and reduce food losses in production. Presently, 13.8% of food is lost in the production and supply chain, and therefore, some companies have started employing circular economy practices using the outputs of food production as inputs for new innovative products. These foods are often termed upcycled foods. This research is about new food product development using BSG as an ingredient and this study tests consumer acceptance of BSG fortified granolas. A multi-method survey was deployed, containing both quantitative and qualitative questions to obtain a comprehensive picture of how consumers perceive the use of BSG in food products. Due to the COVID-19 restrictions, the research was conducted in an uncontrolled environment at participants’ homes, using elements of both sensory tests and product concept tests. Participants (N=45) evaluated three BSG fortified granolas and one commercial granola used as a control product. All participants expressed interest in consuming BSG enriched food products. All four granola samples were rated on taste, sweetness, smell, structure, appearance and overall pleasantness. According to this study, the participants accepted this type of upcycled food and would be interested to purchase BSG fortified products. No statistically significant differences were observed between consumer groups when comparing genders, age groups, diet groups, beer enthusiasts and environmentally conscious consumers. For further research about consumer perceptions towards BSG, a larger sample size is recommended as well as conducting the research as a traditional sensory test in a controlled laboratory setting. Also, further product concept tests or these types of hybrid tests combining elements from both sensory and product concept tests can provide added value for new product development purposes. This master’s thesis is part of the Funbrew transnational project (Biotransformation of brewer’s spent grain: increased functionality for novel food applications) part of the ERA-Net SUSFOOD2 with funding provided by national sources (FORMAS, Sweden; MMM, Ministry of Agriculture and Forestry of Finland; MIUR, Ministero Italiano dell’Università e della Ricerca) and co-funding by the European Union’s Horizon 2020 Research and Innovation Programme.

    This study examines the state of the art of the literature in the domain of food loss and waste (FLW) in food supply chains (FSC). The authors used a systematic literature review (SLR) approach to examine and synthesise the findings of the existing literature to identify the key research themes, research gaps and avenues of future research on FLW in FSC. To this end, this SLR considered 152 articles relevant for the review. The authors uncovered the extant literature in the domain by presenting the research profile of the selected studies, along with thematic analysis. The authors identified eight key themes from the extant literature. The themes range from factors responsible for FLW generation to new, emerging areas of research such as digitalisation and food surplus redistribution. The study's findings will help clarify existing practices in FSC for waste mitigation and act as a foundation for strategic and policy initiatives in this area. The findings indicate that the major factors responsible for FLW include the poor management of perishable food items, stakeholder attitudes, buyer-supplier agreements and supply chain interruptions. Some of the important implications of the study include formal guidelines and policy-level interventions for assisting the accurate quantification of FLW along with an impetus on digitalisation to reduce FLW. The study concludes with the development of a research framework to assist future research in this domain. (c) 2021 The Author(s). Published by Elsevier Ltd.

    Market implementation of active and intelligent packaging (AIP) technologies specifically for fiber-based food packaging can be hindered by various factors. This paper highlights those from a social, economic, environmental, and legislative point of view, and elaborates upon the following aspects mainly related to interactions among food packaging value chain stakeholders: (i) market drivers that affect developments, (ii) the gap between science and industry, (iii) the gap between legislation and practice, (iv) cooperation between the producing stakeholders within the value chain, and (v) the gap between the industry and consumers. We perceive these as the most influential aspects in successful market implementation at a socioeconomic level. The findings are supported by results from quantitative studies analyzing consumer buying expectations about active and intelligent packaging (value perception of packaging functions, intentions to purchase AIP, and willingness to pay more) executed in 16 European countries. Finally, in this paper, we discuss approaches that could direct future activities in the field towards industrial implementation.

    Purpose This study aims to examine the role of hunger, environmental, economic, landfill and water shortage concerns as significant dimensions of consumer social awareness marketing in socially responsible plate food consumption. Design/methodology/approach To carry out their purpose, the authors validate the hypothesized model empirically through data from 1,536 households using structural equation modeling (SEM). In particular, the construct measures of the structural model have been tested by confirmatory factor analysis (CFA). Findings The outcome the authors came up with is coherent with the hypothesized model, and it proves a positive relationship of the five dimensions identified on consumer awareness. Moreover, the study results show the crucial role of landfill and water shortage concerns in measuring consumer awareness. Practical implications These findings may be of interest to practitioners, academics and policymakers for socially responsible food consumption guidance and training for planning consumer awareness programs. More in detail, this study offers the indication that the dimensions of the social consumer awareness construct are differing from commercial consumer awareness. Originality/value Even though several previous studies have addressed the concept of consumer awareness concerning product and service purchase decisions, this is one of the first research studies on consumer awareness as a multidimensional construct in social marketing studies domain.
