    • Bulk optical of potato flesh in the 500 – 1900 nm range 

      López-Maestresalas, Ainara Upna; Aernouts, Ben; Beers, Robbe van; Arazuri Garín, Silvia Upna; Jarén Ceballos, Carmen Upna; Baerdemaeker, Josse de; Saeys, Wouter (Springer US, 2015)   Artículo / Artikulua  OpenAccess
      In this study, the optical properties of potato flesh tissue were estimated using double-integrating sphere (DIS) measurements combined with an inverse adding-doubling (IAD) light propagation model. Total reflectance, ...
    • Evaluation of mechanical tomato harvesting using wireless sensors 

      Arazuri Garín, Silvia Upna; Arana Navarro, Ignacio Upna; Jarén Ceballos, Carmen Upna (MDPI, 2010)   Artículo / Artikulua  OpenAccess
      The harvesting of processing tomatoes is fully mechanised and it is well known that during harvest, fruits are subjected to mechanical stress causing physical injuries, including skin punctures, pulp and cell rupture. Some ...
    • Evaluation of risk factors in fatal accidents in agriculture 

      Arana Navarro, Ignacio Upna; Mangado Ederra, Jesús; Arnal Atarés, Pedro Upna; Arazuri Garín, Silvia Upna; Alfaro López, José Ramón Upna; Jarén Ceballos, Carmen Upna (Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2010)   Artículo / Artikulua  OpenAccess
      En el ámbito agrario se producen anualmente muchos accidentes mortales, no siendo todos ellos registrados oficialmente como accidentes laborales. El objetivo de esta investigación es comparar los datos reales y oficiales ...
    • Mathematical models to describe the volumetric shrinkage rate of red beans during drying 

      Correa, P. C.; Resende, O.; Arazuri Garín, Silvia Upna; Jarén Ceballos, Carmen Upna; Oliveira, Gabriel H. H. de (Associação Brasileira de Engenharia Agrícola, 2011)   Artículo / Artikulua  OpenAccess
      The present study aimed to determine the volumetric shrinkage rate of bean (Phaseolus vulgaris L.) seeds during air-drying under different conditions of air, temperature and relative humidity, and to adjust several ...
    • A multi-year analysis of traffic accidents involving agricultural tractors 

      Arnal Atarés, Pedro Upna; López-Maestresalas, Ainara Upna; Arazuri Garín, Silvia Upna; Mangado Ederra, Jesús; Jarén Ceballos, Carmen Upna (AIDIC, 2017)   Artículo / Artikulua  OpenAccess
      The agricultural sector in Spain is responsible for a high rate of accidents every year, and many of them are traffic accidents. Tractors are a relatively rare sight on roads, meaning that the incidence of accidents involving ...
    • Non-destructive detection of blackspot in potatoes by Vis-NIR and SWIR hyperspectral imaging 

      López-Maestresalas, Ainara Upna; Keresztes, Janos C.; Goodarzi, Mohammad; Arazuri Garín, Silvia Upna; Jarén Ceballos, Carmen Upna; Saeys, Wouter (Elsevier, 2016)   Artículo / Artikulua  OpenAccess
      Blackspot is a subsurface potato damage resulting from impacts during harvesting. This type of bruising represents substantial economic losses every year. As the tubers do not show external symptoms, bruise detection in ...
    • Phytochemicals determination and classification in purple and red fleshed potato tubers by analytical methods and near infrared spectroscopy 

      Tierno, Roberto; López-Maestresalas, Ainara Upna; Riga, Patrick; Arazuri Garín, Silvia Upna; Jarén Ceballos, Carmen Upna; Ruiz de Galarreta, José Ignacio Upna (Wiley, 2016)   Artículo / Artikulua
      BACKGROUND: Over the last two decades, the attractive colours and shapes of pigmented tubers and the increasing concern about the relationship between nutrition and health have contributed to the expansion of their ...
    • Prediction of main potato compounds by NIRS 

      López-Maestresalas, Ainara Upna; Pérez Roncal, Claudia; Tierno, Roberto; Arazuri Garín, Silvia Upna; Ruiz de Galarreta, José Ignacio Upna; Jarén Ceballos, Carmen Upna (AIDIC, 2017)   Artículo / Artikulua  OpenAccess
      Potato (Solanum tuberosum, L) compounds are generally determined by analytical methods including gasliquid chromatography (GLC), HPLC and UV-VIS spectrophotometry. These methods require a lot of time and are destructive. ...
    • A review of the application of near-infrared spectroscopy for the analysis of potatoes 

      López-Maestresalas, Ainara Upna; Arazuri Garín, Silvia Upna; García Ruiz, Ignacio; Mangado Ederra, Jesús; Jarén Ceballos, Carmen Upna (American Chemical Society, 2013)   Artículo / Artikulua  OpenAccess
      Potato (Solanum tuberosum L.) is one of the most important crops in the world being considered as a staple food in many developing countries. The potato industry like other vegetable and fruit industries is subject to the ...
