Methodologies for the replacement/reduction of sulfur dioxide use during winemaking
Cláudia Nunes is Researcher in CICECO – Institute of Materials of Aveiro at University of Aveiro. She graduated in Chemistry in 1999, completed the Master’s in Food Chemistry in 2002, and the PhD in Biochemistry was concluded in 2008 at University of Aveiro (UA). Motivated by the interest in food chemistry, she has a postdoc supported by FCT on preservative strategies for wine avoiding the use of sulfites. One of the main achievements was the development of active chitosan films and their application in wine preservation to replace sulfur dioxide, published in Green Chem (IF=8.506), as an outcome of an international patent, 13 papers, 2 PhD and 6 MSc thesis, and 4 awards (3 best poster/oral presentation in Congresses and 1 as Entrepreneurship idea). In 2015, C. Nunes enlarge the interests to materials science, integrating CICECO on the development of functional bionanocomposites based on polysaccharides, enhancing their functionality (e.g electrical conductivity), broading the fields of applications to biomedical and food packaging. Since the beginning of the career (2006), were published 1 patent, 4 book chapters, and 54 papers in international peer reviewed journals with 731 citations (h=18), excluding self-citations, being the main subject areas Chemistry (48%), Agric. Biol. Sci. (38%), and Materials Sci. (31%). C. Nunes supervised with success 1 PhD, 21 MSc, and 23 BSc students, as well as 7 research fellows, and have more than 100 communications in national and international congresses, including 20 oral communications (3 as invited, Keynote and Plenary Speaker). At the moment, C. Nunes research team is constituted by 4 PhD students, 3 MSc students, and 1 research fellow.
Francisco Antunes was born in Lisbon. He graduated in University of Évora in Agricultural Engineering and holds a degree in Enology from the Institute of Oenology in Bordeaux. With a long history in the vineyard sector, he worked in Quinta de S. Francisco (casa da família), Adega Cooperativa de Pegões, Caves Borlido, Estação Vitivinícola da Beira Litoral. He lectured at Escola de Viticultura da Bairrada. He is, since 1993, winemaker of Aliança Vinhos de Portugal (ex-Caves Aliança), where he is responsible for the Oenology Department.
Over the years, he has developed several research projects, he is a permanent member of Câmara de Provadores da CV Bairrada, and wine taster in several international competitions. He worked with Pascal Chatonnet and Michael Rolland, two of the most prestigious French winemakers. Along the way, he received numerous prizes and distinctions for its wines in the most diverse contests and prestigious publications of the national and international sector (Wine Spectator, Decanter, Wine Enthusiast), as well as the distinction of “Best Winemaker” by the Essência do Vinho (2006).
