The present paper deals with the issue of food waste in selected European countries, in which we have tried to analyze the socioeconomic rations. The main aim of our research was to analyze food waste quantity and compare the amount of wasted food in European Union countries (except Cyprus due to the unavailability of food waste data). The analysis was based on a dataset provided through the Food Waste Index Report 2021 by the UN environment program and complemented by socioeconomic variables obtained from EUROSTAT. For a deeper analyses of the obtained results, we formulated three assumptions, which have been tested with the use of several statistical methods—Pearson’s correlation coefficient, linear regression, the distance from a fictitious object method, and hierarchical clustering. Our results show that the amount of food wasted in different sectors (retail, food, households) is not correlated, and any of the analyzed socioeconomic variables do not influence the ranking of countries by the crucial variable.

The increasing problem of plastic pollution from food packaging created a new market potential for inventing environmental-friendly packaging in the food market including edible food packaging. The main objective of the study was to identify attitudes and perceptions of young people toward edible food packaging. Primary research was conducted via a questionnaire survey. The research sample involved 22 respondents between 19 and 30 years from Slovakia. A questionnaire survey was interconnected with sensory analysis where respondents tested 23 samples of edible food packaging. The results showed that consumers perceive as the most important aspect of food packaging the possibilities of their recycling, followed by the protective function and ecological aspect, while the least important aspect was the design of the packaging. The best rating based on the taste was obtained by sample no. 22 (Mentha × Piperita) while the worst rating was obtained by sample no. 3 (Zingiber officinale). The majority of tested edible food packaging had an indifferent taste.

Sustainability and innovation are key elements of the economic growth and productivity in the contemporary era. The willingness, ability, and capacity to innovate is a strategic tool for the Slovak agro-food companies that want to maintain and/or to improve their market. The aim of this paper is to discuss the selected aspects and determinants of innovative performance of the Slovak agro-food companies and point out key areas and types in innovations, problems influencing their implementation, and assessing their success. The issue of innovation and the “new” role of the agro-food sector have become crucial in the context of transition of the Slovak economy toward more sustainable approaches. Therefore they have become important topics of both scientific research and policy agendas. Using a case study method, a questionnaire survey among 99 agro-food companies in Slovakia was carried out to obtain empirical data about the way how they manage, implement and evaluate the innovations. The study outlined the selected aspects and key determinants which affect the motivation of agro-food companies to innovate as well as selected factors influencing the processes of implementation and management of innovation. The research findings also point out that substantial changes will be required in regulation and support of innovations in the agro-food sector in Slovakia. The study could contribute to help the agro-food companies' managers to improve the innovation activities and competitiveness of their companies, and it would be also helpful for public administration in the development of policies and instruments supporting innovations in the agro-food sector.

The point of purchase is considered to be one of the few communication channels that is not yet saturated, and it has a relatively large potential for the future. A pleasant smell is also part of the shopping atmosphere. How smell affects customer behaviour and purchasing decisions is addressed by a relatively young scientific field, one of the existing kinds of sensory marketing—aroma marketing, otherwise called aromachology. Smell has mainly a subconscious influence; therefore, its examination is appropriate to be carried out using consumer neuroscience tools. This paper examined the perception of the shopping atmosphere in Slovak grocery shops and comprehensive interdisciplinary research on the impact of selected aromatic compounds on the cognitive and affective processes of the consumer, as well as the evaluation of the effectiveness of their implementation in food retail establishments. At the end of the paper, we recommend the possibilities of effective selection and the implementation of aromatisation of different premises, by which the retailer can achieve not only a more positive perception of the shopping atmosphere, but also an increase in retail turnover in individual sales sections.
