- Evaluation of Textural Properties in Apples of Regional VarietiesPublication . Raquel, Guiné; Andrade, S.Regional varieties of apples present an endogenous patrimony that should be preserved and promoted as a means of guarantying biodiversity of genetic resources. In the present work Texture Profile Analysis (TPA) was performed to apples of twenty different regional varieties, having in consideration the spatial geometry of the fruits, and the textural parameters: hardness, adhesiveness, springiness, cohesiveness, and chewiness were assessed. The samples to perform the TPA’s were obtained from different locations inside the fruit - external and internal - and considering axial and radial orientations. The results of the analysis performed allowed us to conclude that the apples from regional varieties show different textural properties among themselves. The varieties Durázio, Lila, Malápio de Gouveia and Malápio TF are the harder ones, whereas Focinho de Burro and Pipo de Basto are the softer. As to the influence of orientation and position in the fruit, it was generally observed that hardness does not vary much according to the internal or external location of the sample inside the apple, but varies quite significantly according to the orientation, being generally higher in the axial measurements. From the present work was possible to conclude that among the Portuguese regional apples studied important differences were encountered in terms of textural properties.
- Projecto industrial de uma adega e centro de aproveitamento de subprodutosPublication . Teixeira, L.; Andrade, S.; Guiné, RaquelEste trabalho, realizado no âmbito da disciplina de Seminário de Projecto da Licenciatura em Engenharia das Indústrias Agro-Alimentares, consistiu na elaboração de um projecto para a instalação de uma Adega e de um Centro de Aproveitamento de Subprodutos da Vinificação. Foram analisadas várias questões relacionadas com a instalação dos edifícios, características das estruturas, aquisição e instalação dos equipamentos, circuitos de produção, balanços de materiais, entre outros, culminando com uma breve análise económica. Dos resultados obtidos foi possível concluir que ambas as unidades têm viabilidade económica.
