Ovalbumin produced using the fungus Trichoderma reesei (Tr-OVA) could become a sustainable replacement for chicken egg white protein powder -a widely-used ingredient in the food industry.Although the approach can generate ovalbumin at pilot-scale, the environmental impacts of industrial scale production have not been explored. Here, we conduct an anticipatory life cycle assessment using data from a pilot study to compare the impacts of Tr-OVA production with an equivalent functional unit of dried chicken egg white produced in Finland, Germany, and Poland. Tr-OVA production reduced most agricultureassociated impacts such as global warming and land use. Increased impacts were mostly related to industrial inputs such as electricity production, but were also associated with glucose consumption.Switching to low carbon energy sources could further reduce environmental impact -demonstrating the potential benefits of cellular agriculture over livestock agriculture for ovalbumin production.

Studies of nostalgia are one of the research subfields of recalled consumption experiences. In addition to the nostalgic recall, the consumers' remembered experiences situate in other temporal frames, a theme rarely touched in the extant research. The aim of this research was to examine the differences between nostalgic and other recalled consumption experiences by identifying and analysing the characteristics of the temporal frames. The data set for this task comprised 480 descriptions of consumers' experiences involving an everyday consumer object. An interpretive approach was utilized to analyse the temporal frames. The results of the study indicate that the consumers described their memories in four temporal structures. These are the strong nostalgia from childhood, light nostalgia from youth, descriptions of recent past and memories linked to consumption practices and traditions that will be fostered in the future. The article proposes a conceptual framework describing the temporal frames of consumers' remembered consumption experiences that opens further avenues for research alongside of nostalgic recall.consumption experience, nostalgia, ordinary objects, remembered experience, temporal frames, temporality

The consumer's role in the packaging value chain thinking has increased. This paper identifies the basic functions of packaging as well as the importance of the visual and structural elements from the consumer's view. However, it is unclear what packaging experts associate with consumers' packaging interactions. Professionals working in the field are still in the key position of defining directions in the packaging industry. The paper investigates how professionals perceive consumer interactions with packaging, and identifies challenges in consumer-centred packaging development. The research materials were collected from 14 theme interviews with representatives of higher education, packaging research and packaging design agencies. As a result, five narratives and five challenges for consumer-centred packaging development were constructed. The narratives describe the following: (a) the symbiotic product-packaging relationship; (b) the everyday context highlighted in purchase and use situations; (c) how consumers become aware of packages; (d) a fashion system of packaging; and (e) everyday routines and rituals involving packaging. The aims of the paper are to raise the awareness of how professionals perceive consumer interaction with packaging, to provide insight into factors relevant for consumer-centred packaging development in industry and to identify the potential challenges, from the professionals' view, for adopting a consumer-centred model.
