- Bee Brood as a Food for Human Consumption: An Integrative Review of Phytochemical and Nutritional CompositionPublication . Guiné, Raquel; Florença, Sofia G.; Barroca, Maria João; Costa, Cristina Amaro daThe utilisation of edible insects for human nutrition is a long-standing practice in many parts of the globe, and is being gradually introduced into countries without an entomophagic tradition as well. These unconventional sources of protein of animal origin have arisen as a sustainable alternative to other animal protein sources, such as meat. This review intends to present the compilation of data in the scientific literature on the chemical composition and nutritional value of the bee brood of A. mellifera species and subspecies as edible foods. For this, a comprehensive search of the scientific literature was carried out using the databases ScienceDirect, Scopus, Pub-Med, BOn, and SciELO. Appropriate keywords were used for the search to reach the research works that addressed the topics of the review. The results showed that bee brood has considerable quantities of protein, fat and carbohydrates. The most abundant amino acids are leucine and lysine (these two being essential amino acids) and aspartic acid, glutamic acid, and proline (these three being non-essential amino acids). As for the fatty acids, bee broods contain approximately equal fractions of saturated and monounsaturated fatty acids, while the polyunsaturated fatty acids are negligible. The dietary minerals present in higher quantities are potassium, phosphorus, and magnesium, and the most abundant vitamins are vitamin C and niacin; choline is also present, although it is not a true vitamin. Although bee brood from A. mellifera has potential for human consumption as a nutrient-rich food, there are still many aspects that need to be further studied in the future, such as safety and hazards linked to possible regular consumption.
- Edible Insects – Exotic Food or Gastronomic Innovation? Study Involving 14 CountriesPublication . de Pinho Ferreira Guiné, Raquel; Elena Bartkiene; Monica Tarcea; Cristina Chuck-Hernández; Ilija Djekic; Marijana Matek Sarić; Nada M. Boustani; Malgorzata Korzeniowska; Dace Klava; Maria Papageorgiou; José Maria Fresno Baro; Maša Cernelic Bizjak; Emel Damarli; Florença, Sofia de Guiné e; Costa, Cristina Amaro da; Correia, Paula; Ferreira, Manuela; Cardoso, Ana Paula; Margarida Campos, Sofia; Anjos, Ofélia; Ferreira, VanessaThis 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.
- The interplay between body mass index, motivation for food consumption, and noncommunicable diseases in the European population: A cross-sectional studyPublication . Marija Ljubičić; Marijana Matek Sarić; Tamara Sorić; Ana Sarić; Ivo Klarin; Boris Dželalija; Alan Medić; Ivo Dilber; Ivana Rumbak; Jasmina Ranilović; Maria Papageorgiou; Viktória Szűcs; Elena Vittadini; Dace Klava; Lucia Frez Muñoz; Małgorzata Korzeniowska; Monica Tarcea; Ilija Djekić; Maša Černelič Bizjak; Guiné, Raquel; Leonardo RoeverIntroduction Consuming unhealthy foods in emotional states can increase body mass index (BMI), contribute to becoming overweight, and lead to the development of chronic diseases. This study aims to investigate the associations between BMI, emotional motivation for food consumption, and health outcomes. Materials and methods “The Motivations for Food Choices” (EATMOT) questionnaire was used to assess the emotional components of food consumption in 9,036 individuals from 12 European countries. The multivariate analysis included linear and logistic regression to examine associations between variables. Results Regression models confirmed associations between BMI, emotional motivation for food consumption (β = 0.13; p < 0.001), obesity (β = 0.35; p < 0.001), diabetes mellitus, and hypertension (β = 0.04; p < 0.001 for both). Using food as a coping mechanism for stress contributed to an increase in BMI [OR = 1.31 (95% CI 1.14–1.51); p < 0.001]. Emotional consolation was associated with a higher likelihood of an increased BMI [OR = 1.22 (95% CI 1.03–1.44); p = 0.020] and obesity [OR = 1.47 (95% CI 1.06–2.06); p = 0.022]. Participants with obesity had a greater likelihood of developing noncommunicable diseases, such as cardiovascular diseases [OR = 2.18 (95% CI 1.45–3.28); p < 0.001], diabetes mellitus [OR = 2.02 (95% CI 1.31–3.12); p = 0.001], hypercholesterolemia [OR = 1.62 (95% CI 1.13–2.32); p = 0.009], hypertension [OR = 1.85 (95% CI 1.36–2.52); p < 0.001], and gastric disorders [OR = 1.81 (95% CI 1.16–2.85); p = 0.010]. Conclusion These results underscore the need for targeted public health interventions that address emotional eating behaviors and promote healthier coping strategies to mitigate the risk of obesity and related health complications.
- Validity and reliability of the Turkish version of The Eating Motivations Scale (EATMOT)Publication . Emre Bayraktaroğlu; Fatmanur Özyürek Arpa; Merve Pehlivan; Guiné, RaquelThis study aims to adapt “The Eating Motivations Scale (EATMOT)” scale into Turkish and conduct a validity and reliability study of the scale for the Turkish population. Approval was received from the developer of the EATMOT scale to conduct this study. The scale was first translated into Turkish from English by five experts in their fields and one professional trans - lator fluent in both languages. The scale was then administered to 940 participants whose native language was Turkish and whose ages ranged from 18 to 65. Translation, exploratory factor analysis, and confirmatory factor analysis were applied to evaluate the scale’s validity. In evaluating its reliability, inter-item correlations, the first 27%-last 27% discrimination, and Cronbach’s alpha coefficient were assessed in total-item correlations. Factor analysis showed that item scores were higher than 0.70. The Cronbach’s alpha coefficient of the scale was calculated as 0.82, indicating that the scale is reliable. Cron - bach’s alpha internal consistency coefficients of the subgroups in the scale were found to be varying in the range of 0.6–0.9. It was concluded that the Turkish version of the EATMOT questionnaire is a reliable and valid tool that can be used in field studies to examine the motivations that affect people’s food choices and eating behaviors.
- Comparison of milk consumption habits across two European countries: Pilot study in Portugal and FrancePublication . Guiné, Raquel P. F.; Florença, Sofia de Guiné e; Bréjon, M.; Gonçalves, João Carlos; Ferreira, Manuela; Barroca, Maria João; Fragata, AnabelaHumans have been consuming milk obtained from domesticated animals since ancient times. Milk is a very complete food with important nutrients that can sup- port life. However, the patterns of consumption of milk have been shifting. On one hand, due to the increase in the number of people with intolerances (to lactose, for example), and on the other hand, due to some trend to avoid foods from animal origin owing to speci fi c convic- tion (like animal welfare, for example). In this context, this study focused on the milk consumption patterns in two di ff erent European Countries and the evaluation of pos- sible di ff erences. The object of study was milk obtained from animal sources, namely, cows, and no other derived fermented dairy products were included. For the develop- ment of the study, a questionnaire survey was applied to a sample of 542 participants from both countries using the Internet. The results showed that a high percentage of participants in both countries consume milk regularly, and the usual amount varies between 125 and 250 mL per day. For those who do not consume milk, the most relevant reason pointed out in both countries was because they do not feel the need to consume it. While in France, a high percentage also do not consume because they do not like milk, and in Portugal, a high percentage do not consume milk due to lactose intolerance. The most con- sumed is semi-skimmed milk, and preferences are towards consuming plain milk or consuming it with chocolate. Signi fi cant di ff erences were found in the consumption of white brands, which are preferred in France, while in Portugal, consumers prefer commercial brands, as well as the preferred package, tetra packs for the Portuguese, while the French prefer plastic bottles. In conclusion, although the results showed some similar trends among the participants from both countries, some di ff erences were also identi fi ed that can be used to better plan public policies in both countries.
- Characterization of Sustainable Food Initiatives: Preliminary Study.Publication . Florença, Sofia de Guiné e; Amaral, Ana Luísa; Costa, Filipa; Guiné, Raquel; Amaro da Costa, Cristina IsabelAbstract: A sustainable food system can be described as a system that ensures economic, social, and environmental sustainability to secure food and nutrition for current and future generations. The present research aimed to identify and characterize sustainable food initiatives to understand the governance framework, the motivations, the reasons for success, the typology of actors involved, and future prospects. Semi-structured interviews were conducted for seven initiatives between June and August 2024. The interviews were performed online, recorded, transcribed, and analyzed. The results showed that the main drivers of the initiatives relate to food, sustainability, and economic and social dimensions. Moreover, one of the reasons for the success of the initiatives is the availability and commitment of the people involved. These initiatives were created to meet local needs and promote sustainability as well as to encourage economic circularity, knowledge sharing, rural and local valorization, and waste management.
- Greenhouse Gas Emissions and Ryegrass Yield after Application of Solid-Liquid Pig Slurry and Biochar to an Agricultural SoilPublication . Pereira, José Luís da Silva; Perdigão, Adelaide; Bonifácio, Gabriel; Figueiredo, Vitor; Marques, Francisco; Trindade, Henrique; Ferreira Wessel, DulcineiaBackground: The application of animal slurry to the soil improves its quality, as manure contains many nutrients for plants. However, this could negatively impact the environment. Objective: This field study investigated the effects of the addition of biochar after the mechanical separation of Whole pig Slurry (WS) into Solid (SF) and Liquid Fractions (LF) on Greenhouse Gases (GHG) emissions (N2O, CO2, and CH4) and ryegrass (Lolium multiflorum Lam. cv magnum) yield. Methods: Biochar (1.0 kg m-2) was applied in plots alone or together with each of the three slurries (80 kg N ha-1) in a total of eight treatments with three replications, including just soil with and without biochar as controls. Soil properties, Greenhouse Gas (GHG) fluxes, and yield were measured during theautumn/winter growing season. Results: The results showed that the addition of biochar to these three slurries significantly increased the soil pH and showed no impact on the other physicochemical properties. The GHG emissions were not significantly different between treatments with and without biochar. The N use efficiency increased significantly in SF > WS > LF, whereas no differences were observed among these three slurries with and without biochar. Conclusion: It can be concluded that the addition of biochar combined with WS or SF/LF to sandy-loam soil appears to have no impact on GHG emissions and ryegrass yield during the autumn/winter season. Overall, this finding suggests that amounts higher than 1.0 kg m-2 of biochar combined with SF may need to be applied to soil to reduce GHG emissions and nitrate leaching and increase N use efficiency and crop yield
- Production and characterization of powder from drone brood of honeybees (Apis mellifera)Publication . Goncalves, J. C.; Vouga, Beatriz; Costa, Cristina Amaro Da; Gonçalves, Fernando Jorge; Coelho, Catarina; Guiné, Raquel; Correia, PaulaDrone bee brood are a natural source of food with potential for human nutrition. This work aims to investigate the production and extraction of the drone bee brood (larvae and pupae), as well as the production of powder from this insect for food applications. To produce the drone brood (DB), in some hives of the colony appropriate empty frames were placed. Some measurements were done in the hive to monitor the global wellbeing of the colony, namely, temperature, relative humidity, and weight. After approximately one month, the frames were removed from the hives and frozen. The yield of DB by frame was 38%. For the extraction of the drone brood, different methods were tested, being the best ones the cold room extraction (∼ 6.5 °C), on a cold surface extraction (∼ 11 °C), and in boiling water extraction (100 °C). The results show that the extraction efficiencies were 74.3% (336.3 s), 62.5% (246.8 s) and 84.9% (332.0 s), for extraction in a cold room, on a cold surface, and in boiling water, respectively. After extraction, two drying processes were tested: evaporation and freeze-drying, being the last one the recommended, preserving in a better way the appearance and composition of the DB. DB powders presented different colour characteristics according to the extraction method used. The powder obtained by boiling extraction was darker than the one produced with cold extraction. Powders are rich in protein, fat and carbohydrates, being the fat content quite high for DB powders produced by boiling extraction method.
- Reference dietary patterns in Portugal: Mediterranean diet vs Atlantic dietPublication . Guiné, Raquel; Florença, Sofia De Guiné E; Amaral, Ana Luisa; Costa, Cristina Amaro DaPortugal is influenced by the Atlantic Ocean to the west and the Mediterranean Sea to the south. Thus, the dietary patterns in Portugal include both the Mediterranean diet (MD) and the Atlantic diet (AD). This review examines the characteristics of both diets, highlighting their commonalities and unique features. This descriptive literature review analyses scientific articles on the MD and AD. It addresses the health effects of both diets based on published evidence. It includes a review of 15 studies specifically focused on the Portuguese population. Most of the studies were conducted with younger people (children or adolescents) or older people, and some were made with patients suffering from a specific pathology, like heart disease, AIDS, or macular degeneration. Both diets emphasize natural, local, and seasonal foods prepared using traditional methods. They consist of foods rich in macronutrients, micronutrients, and bioactive compounds that offer health benefits. Both the MD and the AD are recommended as healthy diets, associated with physical activity as fundamental elements of a healthy lifestyle promoting general well-being. While the health effects of the MD have been extensively studied, the AD remains under-researched.
- Towards the Valorization of Elderberry By-Product: Recovery and Use of Natural Ingredients for Sorbet FormulationsPublication . Neves, Cláudia M. B.; Fogeiro, Élia; Cardoso, Susana M.; Gonçalves, Fernando Jorge; Pinto, António; Ferreira Wessel, DulcineiaOne of the food industry’s greatest challenges is to find natural ingredients capable of conferring antioxidant and color properties. In addition, the agri-food industry generates by-products that are often treated as waste, despite their abundance of phytochemicals that can be recovered and used as food ingredients. This study explores the potential of elderberry pomace, an industrial by-product of juice processing rich in anthocyanins and polyphenols, as a natural food additive in blueberry sorbet. Elderberry pomace was incorporated into the sorbet formulation in powder form or as aqueous extracts at two different concentrations. The analysis of the pomace extract by UHPLC-DAD-MS showed the presence of four anthocyanins: cyanidin-3,5-O-diglucoside, cyanidin-3-O sambubioside-5-O-glucoside, cyanidin-3-O-sambubioside, and cyanidin-3-O-glucoside. The physicochemical properties of the sorbets such as pH, ◦Brix, overrun, melting rate, and color were evaluated, as well as their levels of total phenolic compounds, total monomeric anthocyanins, and in vitro antioxidant activity. The potential of sorbets to stimulate the growth of probiotic bacteria was evaluated and a sensory analysis was conducted to assess consumer acceptance. Results indicated that the sorbet containing the more concentrated extract presented higher overrun, faster melting rate, higher contents of phenolic compounds and anthocyanins, and higher antioxidant activity compared to the control. Additionally, this formulation showed a darker hue (lower L* value) and a tendency to stimulate probiotic bacteria. Moreover, the sorbets with pomace in their composition had good consumer acceptability. These findings highlight the potential of elderberry pomace to be used as a natural, sustainable ingredient in the ice cream industry, aligning with growing consumer trends towards healthier and eco-friendly products.
