- Chapter four - Edible Insects: Perceptions of Marketing, Economic, and Social Aspects among Citizens of Different CountriesPublication . Guiné, Raquel; Florença, Sofia de Guiné e; Costa, Cristina Amaro da; Gonçalves Oliveira Valente da Cruz-Lopes, Luísa Paula; Esteves, Bruno; Ferreira, Manuela; Fragata, Anabela; Cardoso, Ana Paula; Margarida Campos, Sofia; Anjos, Ofélia; Bartkiene, E; Djekic, I; Matran, IM; Culin, J; Klava, D; Chuck-Hernández, C; Korzeniowska, M; Boustani, NM; Papageorgiou, M; Gutiérrez, BP; Cernelic-Bizjak, M; Damarli, E; Ferreira, Vanessa; Guiné, RPFBecause edible insects (EI) have been, in recent years, recommended as a nutritious animal protein food with enormous environmental advantages over other sources of animal protein for human consumption, studies aimed at investigating the consumer perspective have become more prominent. Hence, this study intended to examine the perceptions of participants from different countries about the commercialization and economic and social impacts of edible insects. The study was made using a questionnaire survey, and data were collected in Brazil, Croatia, Greece, Latvia, Lebanon, Lithuania, Mexico, Poland, Portugal, Romania, Serbia, Slovenia, Spain, and Turkey. The final number of received answers was 7222 participants. For the treatment of the results, different statistical techniques were used: factor analysis, internal reliability by Cronbach’s alpha, cluster analysis, ANOVA to test differences between groups, and Chi-square tests. The results obtained confirmed the validity of the scale, constituted by 12 out of the 14 items initially considered, distributed by 4 factors: the first related to the economic impact of EIs, the second related to the motivation for consumption of EIs, the third related to the places of purchase of EIs, and the fourth corresponding to a question presented to the participants as a false statement. A cluster analysis allowed identifying three clusters, with significant differences between them according to all the sociodemographic variables tested. Also, it was found that the participants expressed an exceptionally high level of agreement with aspects such as the difficulty in finding EIs on sale, knowledge acting as a strong motivator for EI consumption, and the role of personalities and influencers in increasing the will to consume EIs. Finally, practically all sociodemographic variables were found to be significantly associated with perceptions (country, sex, education, living environment, and income), but not age. In conclusion, the perceptions about EI commercialization were investigated and revealed differences among samples originating from different countries. Moreover, the sociodemographic characteristics of the participants were found to be strongly associated with their perceptions
- Determinants of Emotional Eating: A Study Involving Different CountriesPublication . de Pinho Ferreira Guiné, Raquel; Florença, Sofia de Guiné e; Ferreira, Manuela; Margarida Campos, Sofia; Cardoso, Ana Paula
- Consumer Perspectives Towards Edible Insects in a Western CountryPublication . de Pinho Ferreira Guiné, Raquel; Florença, Sofia de Guiné e; Ferreira, Manuela; Margarida Campos, Sofia; Paula Pereira de Oliveira Cardoso, Ana; Justin A. DanielsThis book includes eight chapters that detail recent advancements in environmental research. In Chapter 1, a bibliometric analysis of scholarly works published from 2014 to 2024 examines the relationship between sustainability and organizational justice in Asian higher education. In Chapter 2, the authors examine how seaweed promotes sustainable development and the blue economy and discuss how seaweed helps with food scarcity and environmental degradation. Chapter 3 focuses on the relationship between the microbiome and human health, pathologies and therapeutics of microbes, their contribution towards the environment, their role in modern agriculture and food security, advancements in technologies to study, and ethical and biosafety concerns regarding the handling of microbes. The study in Chapter 4 addresses the urgent issue of wastewater treatment and public water supply in relation to antibiotic resistance. The cost of producing biodiesel from waste vegetable oils was conducted in Chapter 5, along with an evaluation of the economic gains achievable through blending biodiesel with conventional diesel. Chapter 6 addresses issues related to the environment and sustainability and presents and discusses the findings of a study conducted in Portugal as part of the Edible Insects as Sustainable Food (EISuFood) initiative. In chapter 7, the authors address the three levels of grey water management implementation—decentralized, semi-centralized, and centralized—at the individual household, cluster, and village levels, as well as case studies. In the final chapter, the author investigates the vertical wind variability in the vicinity of tropopause.
- Cancer Prevention and Management Trough Phenolic CompoundsPublication . Guiné, Raquel P. F.; Florença, S. G.; Ferreira, Manuela; Campos, Sofia; Okpala, C.; Korzeniowska, M.The chemical molecules included in the class of phenolic compounds encompass a very large variety of structures, constituting numerous families of compounds, such as, for example, the phenolic acids or the flavonoids, of which are particularly relevant the anthocyanins. These molecules, due to their chemical structures with aromatic rings, have a high antioxidant capacity which have proven to be quite beneficial for many health conditions. Among their many health benefits, polyphenols also have been described as providing important tools to prevent or help in the treatment of diverse types of cancer, namely though the regulation of cell signal transduction and gene expression, which allows controlling the development of cancer cells. In this context the present chapter highlights some scientific evidence corroborating the role of polyphenols in the prevention and treatment of cancer.
