    Fruit by-products have a low economic value and have proven biological activities, such as antioxidant capacity due to the presence of active compounds. The main objective of this study was to obtain and determine the antioxidant capacity, through DPPH radical assay and β-carotene bleaching assay, of three food grade extracts from apple, lemon, and orange industrial by-products. Furthermore, the extracts were characterized by ultra-high performance liquid chromatography coupled to mass spectrometry (UHPLC-MS/MS). LC with diode array detector (LC-DAD) was used for the quantification of the main polyphenols. Lemon extract presented the highest inhibition percentage of DPPH radical (51.7%) and the highest total phenolics content (43.4 mg GAE/g) from the by-products studied. Orange by-product was that with the higher number of polyphenols while lemon extract was that with the highest content of individual phenolics. The by-product obtained from the lemon was that with higher amounts of hydroxycinnamic acids (407 µg/g of by-product), mainly chlorogenic acid (386.7 µg/g), followed by the apple by-product (128.0 µg/g of by-product), which showed higher amounts of rosmarinic and chlorogenic acids. These industrial by-products have great potential as a source of natural antioxidants to be used directly as food additives or to be incorporated in packaging to produce active food packaging.

  • Evaluation Report of the Sustainable Capacity Building Programme (European Health Information Training Programme - EHITP): Final Report
    Publication . Garcia, Ana Cristina; Sousa Uva, Mafalda; Roquette, Rita; Gómez, Verónica; Matias Dias, Carlos
    The InfAct (Information for Action) project is a Joint Action of the European Commission's 3rd Health Programme, which includes 28 EU Member States and Associated Countries. The main goal of InfAct is to build an infrastructure of a health information system for a stronger European Union and to strengthen its core elements. Its vision is to improve the use of health data and information for a healthier Europe. Portugal co-leads the Work Package 6 (WP6) of this project, through a team of professionals from the Directorate-General of Health (who coordinates), the Institute of Hygiene and Tropical Medicine - NOVA University of Lisbon and the National Institute of Health Doctor Ricardo Jorge. WP6 includes, among other tasks, the development of a Flagship Capacity Building Programme and its evaluation. The proposal of the programme was presented through the document “InfAct - Sustainable Capacity Building Programme (European Health Information Training Programme - EHITP), Task 6.2 – February 2020”.
