- An insight into the level of information about sustainability of edible insects in a traditionally non-insect-eating country: exploratory studyPublication . Guiné, Raquel P.F.; Florença, Sofia G.; Anjos, O.; Correia, Paula M.R.; Ferreira, Bruno M.; Costa, Cristina A.Insects have been reported as a possible alternative solution to help feed the growing world population with less stress on the planet, thus contributing to the preservation of the environment and natural ecosystems. However, the consumption of edible insects (EIs), although culturally accepted for some communities, is not readily accepted for others. Hence this work explores the level of information that people in a traditionally non-insect-eating country have about the sustainability issues related with EIs, and also some possible reasons that could motivate their consumption. The study was based on a questionnaire survey and the results were explored by descriptive statistic tools, tree classification analysis, factor analysis and cluster analysis. The results showed that the level of information is still low in general, with most people not manifesting an opinion. However, some aspects are relatively familiar to the participants (88.9% know that the ecological footprint of insects is smaller than other meats and 86.9% know that they efficiently convert organic matter into protein). Factor and cluster analysis showed three classes: cluster 1—people not informed about the facts disclosed through the true statements and also not able to distinguish the false information; cluster 2—people not informed about the facts disclosed through the true statements but who were able to distinguish the false information; and cluster 3—people well informed about the facts disclosed through the true statements but who were marginally unable to distinguish the false information. It was also found that education, sex and professional area are the most relevant sociodemographic factors associated with the level of information, and the highest motivations to consume EIs are their contribution to preserve the environment and natural resources followed by being a more sustainable option (for 64.7% and 53.4% of participants, respectively). Hence it was concluded that, although some work still needs to be done to better inform people about EIs, there is already some conscientiousness that they constitute a good and more sustainable alternative to other types of mea
- Are consumers aware of sustainability aspects related to edible insects? Results from a study involving 14 countriesPublication . Guiné, Raquel P.F.; Florença, Sofia G.; Anjos, O.; Boustani, Nada M.; Chuck-Hernández, Cristina; Sarić, Marijana Matek; Ferreira, Manuela; Costa, Cristina A.; Bartkiene, Elena; Cardoso, Ana Paula; Tarcea, Monica; Correia, Paula M.R.; Campos, Sofia; Papageorgiou, Maria; Abarquero Camino, Daniel; Korzeniowska, Malgorzata; Černelič-Bizjak, Maša; Kruma, Zanda; Damarli, Emel; Ferreira, Vanessa; Djekic, IlijaIn recent years, edible insects have been suggested as an alternative food that is more sustainable compared with other sources of animal protein. However, knowledge about the sustainability aspects associated with this source of food may play a role in convincing consumers to adopt insects as part of their diet. In this context, the present study investigated the level of knowledge about the sustainability of edible insects in a group of people originating from 14 countries, with some naturally entomophagous and others not. To measure the knowledge, 11 items were selected and the scores obtained were tested with statistical tools (t-test for independent samples, analysis of variance—ANOVA) to search for differences according to sociodemographic and socioeconomic characteristics, geographical origin, and consumption habits of edible insects. The obtained results showed that, in general, knowledge is moderate, with the values of the average scores for the 11 items investigated ranging from 0.23 ± 0.99 to 0.66 ± 1.02, on a scale ranging from −2 (=very low knowledge) to 2 (=very high knowledge). The highest scores were found for items relating to the lower use of animal feed and lower emission of greenhouse gases required for the production of insects compared with beef. When investigating the differences between groups of participants, significant differences were generally found, revealing a trend for higher knowledge among males and young adults, for participants residing in urban areas and in countries such as Spain, Mexico, and Poland, and for participants with higher education levels and higher incomes. When testing the influence of consumption variables on the level of knowledge, the results showed a higher knowledge for participants who had already consumed insects or are willing to consume them. Finally, it was observed that higher knowledge was found for participants whose motivation to consume insects related to curiosity, a wish to preserve the planet, the gastronomic characteristics of insects, and their nutritional value. In conclusion, these results clearly indicate a very marked influence of a number of variables on the knowledge about the sustainability of edible insects, and this may be helpful to delineate strategies to effectively raise knowledge and eventually increase the willingness to consider insects as a more sustainable alternative to partially replace other protein foods, even in countries where this is a not a traditional practice.
- Biostimulants in organic vegetable nurseries: Study case in lettucePublication . Simões, Joana; Marmota, Carolina; Moreira, Lisa; Costa, Daniela V.T.A.; Correia, Helena E.; Pinto, António; Wessel, Dulcineia; Delgado, F.M.G.; Carneiro, J.P.; Monteiro, M.C.H.; Bahcevandziev, Kiril; Vidal, Maria M.B.; Filipe, Olga M.S.; Costa, Cristina A.In order to create better conditions to achieve food safety and sovereignty, agroecology, as a science, looks for solutions for several steps of the technical itineraries of the crops. Crop nutrition and protection are two main crop itinerary components that have been in the center of farmers challenges and consumers concerns, and biopreparations, which have been prepared using natural substances, have been used in agroecological systems, most times based on farmers empirical knowledge. Six biopreparations—purslane vinegar, prickly pear vinegar, orange fermented fruit juice, garlic extract, nettle infusion, and horsetail decoction—were used in this study, for physicochemical analyses and field tests in two different locations (Viseu and Castelo Branco, Portugal) in nurseries of Lactuca sativa L. (lettuce), and aimed to validate its results and uses. The nettle infusion presented the best stimulating results for the length of aerial part and the garlic extract presented the best results for the length of root, though there weren’t significant differences and effects when compared with the control. The results indicate that the biopreparations used did not exert a biostimulant action in relation to the application of water in lettuce nurseries and that more research is needed to confirm the results observed by farmers.
- Development of a questionnaire to assess knowledge about and perceptions of edible insectsPublication . Guiné, Raquel P.F.; Florença, Sofia G.; Costa, Cristina A.; Correia, Paula M.R.; Ferreira, Manuela; Duarte, João; Cardoso, Ana Paula; Campos, Sofia; Anjos, O.Edible insects (EI) have been consumed as traditional foods in many parts of the globe, but in other regions, they are not readily accepted, particularly in Western countries. However, because EI are suggested to constitute a more sustainable protein food as compared with other sources of animal protein, they can be considered a future food that could help mitigate hunger and malnutrition. Additionally, new gastronomic trends are already targeting this area for exploring new potentialities. The objective of this work was to develop and validate a questionnaire to assess consumers’ perceptions and knowledge about EI in seven different domains: D1. Culture and Tradition, D2. Gastronomic Innovation and Gourmet Kitchen, D3. Environment and Sustainability, D4. Economic and Social Aspects, D5. Commercialization and Marketing, D6. Nutritional Aspects and D7. Health Effects. The 64 items were subjected to item analysis and reliability analysis for validation, and factor analysis was also conducted to identify a grouping structure. The results validated all the items of the seven subscales with high values of Cronbach’s alpha (α = 0.732 for D1, α = 0.795 for D2, α = 0.882 for D3, α = 0.742 for D4, α = 0.675 for D5, α = 0.799 for D6 and α = 0.788 for D7). However, by eliminating 17 items, the final values of the alpha increased in all subscales. Factor analysis with extraction by principal component analysis with varimax rotation extracted 14 factors that explained, in total, 65% of the variance, although the first two factors were the most important (35.7% variance explained). In conclusion, the confirmed usefulness of the questionnaire has been hereby validated for assessing consumer perceptions of and knowledge about EI.

- Edible insects – exotic food or gastronomic innovation? Study involving 14 countriesPublication . Guiné, Raquel P.F.; Florença, Sofia G.; Bartkiene, Elena; Tarcea, Monica; Chuck-Hernández, Cristina; Djekic, Ilija; Sarić, MarijanavMatek; Boustani, Nada M.; Korzeniowska, Malgorzata; Klava, Dace; Papageorgiou, Maria; Fresno Baro, José Maria; Černelič-Bizjak, Maša; Damarli, Emel; Ferreira, Vanessa; Costa, Cristina A.; Correia, Paula M.R.; Ferreira, Manuela; Cardoso, Ana Paula; Campos, Sofia; Anjos, O.This study explores the perceptions about edible insects and their usage in modern gastronomy. Data were collected through questionnaire survey in 14 countries, and 7222 responses were obtained. ANOVA and factor analysis were used, respectively to evaluate differences between groups and to analyze the scale items. The results showed that participants showed higher agreement toward insects being considered exotic foods and being associated with taboos and neophobia. Some sociodemographic factors (country, age class, education level and income) were proven to significantly influence with the perceptions. while sex and living environment did not. Factor analysis extracted three factors, one associated with the uses of insects in gastronomy, another associated with insects as foods and a third about insects not being proper for human consumption. In conclusion, the work revealed differences between countries in the perceptions about edible insects, and that these perceptions were also significantly influenced according to other sociodemographic variables.
- Edible insects: A survey about perceptions regarding possible beneficial health effects and safety concerns among adult citizens from Portugal and RomaniaPublication . Guiné, Raquel P. F.; Florença, Sofia G.; Costa, Cristina A.; Correia, Paula M.R.; Ferreira, Manuela; Cardoso, Ana Paula; Campos, Sofia; Anjos, Ofélia; Bacarea, Vladimir; Bacarea, Anca; Buicu, Gabriela; Szasz, Simona; Martin-Hadmas, Roxana; Tarcea, MonicaAlthough edible insects (EI) have been consumed for ages in many countries around the world, in most European countries, this is not a traditional practice. Still, it has been encouraged as a sustainable source of animal protein besides other nutrients. The Food and Agricultural Organization and the United Nations, recommend consuming EI as a way to contribute to the sustainable development goals. Hence, this research investigated how participants from Portugal and Romania perceive EI, and how these can be useful as a source of nutrients and other benefits for human health, as well as possible risks. For that, it was undertaken a questionnaire survey, with data collected online in the two countries. For the analysis of data, basis statistics and chi-square tests were used. Results showed significant differences between Portuguese and Romanian participants in six out of ten questions, namely regarding safety (p < 0.001), use in traditional medicine (p < 0.001), possible infection with parasites (p = 0.021), of pesticides (p = 0.031), their usage as therapeutics (p = 0.001) and being potential sources of allergens (p < 0.001) and aflatoxins (p < 0.001). Also, differences were tested for other sociodemographic variables. The results showed significant differences according to age for only three questions, gender for only two questions, and Education for most of the questions, i.e., six out of the ten. These results highlighted the greater influence of variables like country of origin and education in the perception of the effects of EI in human health.
- Edible insects: Consumption, perceptions, culture and tradition among adult citizens from 14 countriesPublication . Raquel P. F. Guiné; Sofia G. Florença; Costa, Cristina A.; Correia, Paula M. R.; Lopes, Luísa Cruz; Esteves, Bruno; Ferreira, Manuela; Fragata, Anabela; Cardoso, Ana P.; Campos, Sofia; Anjos, O.; Boustani, Nada M.; Bartkiene, Elena; Chuck-Hernández, Cristina; Djekic, Ilija; Tarcea, Monica; Sarić, Marijana Matek; Kruma, Zanda; Korzeniowska, Malgorzata; Papageorgiou, Maria; González Árias, Leticia; Černelič-Bizjak, Maša; Damarli, Emel; Ferreira, Vanessa; Bayraktaroğlu, Emre; Arpa, Fatmanur OzyurekAlthough edible insects (EIs) are encouraged as a sustainable source of protein, their consumption is not as generalised as other types of food that are internationally accepted. While in some regions of the world, EIs are part of the gastronomic and cultural traditions, in other regions, people are not so receptive to this type of food, and some people even express some disgust towards it. Hence, this research focused on the habits of the participants regarding the consumption of insects as well as their perceptions about EIs being or not a part of the local culture or gastronomic patrimony. A questionnaire survey was implemented in fourteen countries (Brazil, Croatia, Greece, Latvia, Lebanon, Lithuania, Mexico, Poland, Portugal, Romania, Serbia, Slovenia, Spain, and Turkey), and globally, 7222 adult participants responded to the questionnaire. SPSS software (version 28) was used to process the data and carry out chi-square tests and Factor Analyses (FA). The obtained results showed significant differences between countries for all the questions included in the survey, either those regarding the habits of the participants or their opinions about the facts linked with EI tradition or cultural aspects. It was found that participants from Mexico consume EIs more than in all other countries and that strong motivations that would lead to consumption among those who do not consume include curiosity and food shortage. The solution obtained with FA considering the ten statements of the scale consisted of two factors: F1—Culture and Tradition of EIs (α = 0.675) and F2—Acceptance of EIs (α = 0.614). In conclusion, the consumption of EIs and the perceptions of people are highly variable according to geographic location and cultural environment.
- Edible insects: perceptions of marketing, economic, and social aspects among citizens of different countriesPublication . Guiné, Raquel P.F.; Florença, Sofia G.; Costa, Cristina A.; Correia, Paula M.R.; Lopes, Luísa Cruz; Esteves, Bruno; Ferreira, Manuela; Fragata, Anabela; Cardoso, Ana Paula; Campos, Sofia; Anjos, O.; Bartkiene, Elena; Djekic, Ilija; Matran, Irina M.; Culin, Jelena; Klava, Dace; Chuck-Hernández, Cristina; Korzeniowska, Malgorzata; Boustani, Nada M.; Papageorgiou, Maria; Prieto Gutiérrez, Bernardo; Černelič-Bizjak, Maša; Damarli, Emel; Ferreira, VanessaBecause 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 resultsobtained 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.
