- Embalagens no setor do Azeite: Desafios Atuais e InovaçõesPublication . Rodrigues, Nuno; Ferreiro, Nuno; Pereira, José Alberto; Peres, António M.;O azeite virgem, produto obtido exclusivamente por processos mecânicos, é a principal fonte de gordura da dieta mediterrânica, devido à sua composição, mas principalmente pelas suas caraterísticas sensoriais. É um alimento de elevado valor nutricional utilizado na culinária, rico em ácidos gordos monoinsaturados e outros compostos minoritários de grande importância, como os polifenóis, tocoferóis, carotenóides, esteróis e clorofilas. Como todos os alimentos, e em especial os que contêm elevado teor em gordura (no azeite ronda os 99%) está sujeito a processos de degradação, onde a luz, temperatura e oxigénio desempenham um papel fundamental nesse processo e podem afetar negativamente a sua qualidade. A degradação da qualidade é principalmente acelerada quando o azeite é armazenado a temperaturas elevadas, exposto à luz e com disponibilidade de oxigénio, ocorrendo a oxidação do azeite (oxidação lipídica).
- Food Consumption Practices and Implications for Mycotoxin Exposure Risk: A Cross-sectional Study in Inhambane and Gaza Provinces, MozambiquePublication . Ribeiro, Maria Isabel; Mussalama, Edson; Manhiça, Agnaldo; Cabo, Paula; Venâncio, Armando; Rodrigues, Paula; Macuamule, CustódiaDiet is considered the main route of exposure to the risk of mycotoxin poisoning. Consequently, given the prevalence of mycotoxins in Mozambique, there is a need to develop studies on the population's consumption habits to implement control and mitigation strategies in a sustainable way. This quantitative and cross-sectional study aimed to report the dietary habits of the population in two provinces of Mozambique and to investigate whether province, place of residence, gender, and age were differentiating factors in dietary habits. Primary data were collected using a food frequency questionnaire adapted from a validated version for Portugal, which was modified to include foods commonly consumed in Mozambique. The data, collected by agricultural technicians between October and November 2022, refer to 300 individuals from 55 households. According to the results, 58.4% of the products consumed by families were of local origin, 40.2% were of national origin, and only 1.4% were imported. Foods such as milk, oil, fresh fish, eggs, rice, bread, sugar, onions, water, mango, and bananas are part of the daily diet of these households. In addition, it was found that the province, environment, and gender of the participants acted as differentiators of eating habits. That is, a greater quantity of foods from all food groups was consumed in the urban environment compared to the rural one. Considering the province, the consumption of fats, bread, and cereals is higher in Gaza, while, in Inhambane, dairy products, fats, fruits, and beverages are consumed in greater quantities. Finally, considering gender, it was found that women consume a greater quantity of dairy products. These results are crucial for the development of sampling strategies that assess fungal and mycotoxin contamination and estimate the risk of exposure to the studied population.
- Pastagens e forragemPublication . Pires, Jaime; Aguiar, Carlos; Moreira, NunoEste trabalho principia com uma contextualização do empreendimento do Complexo Agro-Industrial do Cachão, destacando-se a atualidade das ações e soluções técnicas então preconizadas, com destaque para a introdução de forragens em rotação com culturas herbáceas e sob coberto de espécies frutícolas. Em seguida e feito um contraponto entre o passado e o presente relativamente ao conhecimento técnico e científico disponível e a disponibilidade comercial de espécies e cultivares pratenses e forrageiras, e analisa-se a evolução do uso do solo, dos efetivos pecuários e dos encabeçamentos em Trás-os-Montes e em Portugal Continental desde 1870 a 2019. Com base nestes dados e perante os baixos efetivos pecuários e encabeçamentos atuais, similares aos ocorridos no final do seculo XIX, apontam-se linhas estratégicas e ações a implementar, com base num modelo de ordenamento cultural para Trás-os-Montes, já que a superfície exterior as explorações agrícolas, ocupada por matos e pastagens em 20 15/!9, representa 33 % da superfície territorial da região. São preconizados sistemas agro-pastoris ou agro-silvo-pastoris que integrem a utilização de superfícies exteriores e próprias das explorações agrícolas, destacando-se as principais vantagens destes sistemas. Apresenta-se por último um sistema agro-pastoril como um caso de estudo na Serra do Alvão, atualmente objeto de um projeto "Life".
- Predictors of the Intention to Buy Organic Products: A Quantitative and Cross-sectional Study in TunisiaPublication . Zaidi, Saida; Fernandes, António; Ribeiro, Maria IsabelOrganic farming plays a very important role in promoting sustainable agriculture by preserving ecosystems, enhancing biodiversity, and ensuring the production of healthier food. As the demand for organic products continues to rise globally, understanding the factors driving organic food consumption becomes essential for fostering sustainable consumer behavior. Tunisia, with its deep-rooted agricultural heritage and growing interest in organic and sustainable living, presents a unique case for examining these dynamics. Given the country’s ongoing economic development and urbanization, it is crucial to examine the factors influencing consumer choices regarding organic products. Thus, this study aims to analyze the factors influencing organic food consumption in Tunisia by assessing consumer attitudes, purchasing habits, and barriers to its implementation. Using a quantitative and cross-sectional approach, data were collected through a structured survey targeting a diverse sample of Tunisians that explored socio-demographic characteristics, economic constraints, motivations, and challenges of consuming organic food. Statistical analysis was applied to identify key trends and correlations. Findings reveal that 23% of respondents purchase no organic products, with supermarkets dominating distribution channels and limited availability through direct farmer sales or specialty stores. Consumer knowledge is notably deficient, with over 60% of participants demonstrating limited understanding of organic food. Regression analysis reveals that attitudes toward organic food are the strongest predictor of purchase intention, followed by health awareness, while perceived price has a negative impact on consumption. Interestingly, environmental concerns showed no significant association with purchase intention. These results underscore the need for strategies that foster positive attitudes and address price concerns to promote the implementation of organic food in Tunisia.
