- The EATMOT Project: Preliminary Results of the study about motivations for food choices in 16 countriesPublication . Guiné, Raquel; Ferreira, Manuela; Correia, Paula; Cardoso, Ana Paula; Ferrão, Ana Cristina; Mendes, Mateus; Duarte, João; Bartkiene, Elena; Tarcea, Monica; Djekic, IlijaEating is not only determined by physiology, but also by many other factors that interact in a complex way to shape individual eating habits. Hence, the aim of this project is to undertake a study about the different psychic and social motivations that determine people’s eating patterns, either in relation to their choices or eating habits. To do this, factors linked to food choices will be evaluated in the following main areas: health motivations; economic factors; emotional aspects; cultural influences; marketing and commercials or environmental concerns. The study is based on a questionnaire that was prepared purposely for the project, and therefore adequate to evaluate the aspects that determine the objectives highlighted. The study is coordinated by the principal researcher Raquel Guiné from CI&DETS Research Centre and the range is multinational, including different countries so as to gather information on a trans-frontier scale. The countries involved are: Argentina, Brazil, Croatia, Egypt, Greece, Hungary, Italy, Latvia, Lithuania, Netherlands, Poland, Portugal (Coordinator), Serbia, Slovenia, Romania and United States of America. This particular study investigated the influence of sociodemographic factors on the six types of eating motivations previously referred. This is a longitudinal observational study carried out on a non-probabilistic sample with 11960 participants residing in the 16 countries afore mentioned. Analysis of the data was performed using t-test for independent samples or ANOVA with Post-Hoc Tukey HSD. Neural network models were also created, to determine the relative influence of each input on each output variable. The results showed that factors such as age, marital status, country, living environment, level of education or professional area significantly influenced all of the studied types of eating motivations. The modelling through neural networks indicated a considerable variability in the food choices, but still it was possible to identify some trends, like for example that the strongest positive factor determining health motivations was age, while for emotional motivations was living environment, and for economic & availability motivations was gender. On the other hand, country revealed a high positive influence for the social & cultural as well as for environmental & political and also for marketing & commercial motivations.
- ValNuts - Valuation of hard shell nuts (FSCR)Publication . Correia, Paula; Guiné, Raquel; Ferrão, Ana Cristina; Elsa, Ramalhosa; Ribeiro, Carlos; Silva, Carlos; Droga, Rui; Ferreira, Nuno; Araújo, JoanaThe hard-shell nuts sector (FSCR) plays a fundamental role in the sustainability of the economies of the rural regions in Portugal. The characterization of varieties, as well as the identification of factors and possible preventive activities could avoid the appearance of defects in these fruits (e.g. bitterness), and also value these fruits for different purposes, such as cooking, cosmetics and pharmaceutical industry. The lack of knowledge by producers as to the best processes for the conservation of nuts can lead to considerable economic losses, leading to significant defects (e.g. rancid). Also, industrial producers face serious problems when they export FSCRs to tropical countries (which are important customers) as they have to deal with environments with high humidity, high temperatures, and long transport times. Hence, this project aims to enhance the production of hard-shell nuts in Portugal, with a view to boosting its production, increasing its economic value and promoting the export capacity of FSCR producers. The project was desigedn to study almonds, hazelnuts and walnuts, and it is divided in three stages: promotion and characterization of nuts varieties existent in Portugal, post-harvest technologies - process and product innovation, and transfer of knowledge and dissemination of results. the first stage intends to determine the most important varieties commercialize in Portugal using a survey applied to producers. after the identification, these varieties are characterized considering the physicochemical, biological and sensorial properties. establishment of good practices to be followed by FSCR producers and their effect on fruit quality are also other tasks, following some producers through the creation of working groups. The second stage is constituted by five activities: (1) Characterization of the storage and distribution conditions that FSCRs in shell (walnut), kernel (hazelnut and almond) and laminates (almond) are subject during national and European commercialization and determination of the main problems; (2) Characterization of fluvial transport conditions to which kernel and almond laminates are subjected when exported to tropical countries; (3) Characterization of the main physical, chemical, biological and sensorial agents responsible for the losses of quality of the almond exported to tropical countries; (4) Evaluation of the behavior and adaptability to the environmental conditions of transport to tropical countries of several varieties of almond; (5) Implementation of effective post-harvest technologies to promote the export of FSCRs to Europe and tropical countries. The last stage wants to create some focal groups, a webpage of the project, as well as to develop of informative brochures, seminars and publications. The obtained results will be most valuable to produce relevant technical and scientific outputs as well as directives that could be used by the producers and industrials to improve the hard-shell nuts’ sector.
