Carocho, Márcio; Antonio, Amilcar L.; Barreira, João C.M.; Rafalski, Andrzej; Bento, Albino; Ferreira, Isabel C.F.R.Chestnuts are widely consumed around the world, especially in China, which is the major producer. Portugal is the fifth biggest producer, reaching and income of 17 M€, with particular relevance for Trás-os-Montes region, which is responsible for 81% of Portuguese production. During postharvest storage, a number of pests tend to attack chestnuts, contributing to high economic losses. Since 2010, the most effecti...
Application of gamma and electron beam irradiation for chestnuts conservation
Carocho, Márcio; Antonio, Amilcar L.; Barreira, João C.M.; Barros, Lillian; Rafalski, Andrzej; Botelho, M. Luísa; Oliveira, M.B.P.P.; Bento, AlbinoDue to the distribution of low quality products, adulteration, counterfeit on the Ukrainian market, the widening of export-import supplies, it is too important to develop criteria and methods for the identification domestic and exported food products, detection of adulteration, techniques and methods assessing quality and early spoilage screening of food products using modern express methods of analysis. Such m...
Gamma and electron beam irradiation as an alternative for postharvest treatment...
Carocho, Márcio; Antonio, Amilcar L.; Barreira, João C.M.; Barros, Lillian; Rafalski, Andrzej; Bento, Albino; Ferreira, Isabel C.F.R.Chestnut fruits are an important food commodity in the Northeast region of "Trás-osMontes", representing an income of approximately 17 M€ and being Porn1gal one of the: world's biggest producer. Due to environmental concerns a broad spectrum fumigant, methyl bromide, was banned in 20 I 0 by the European Union. Since then, no adequate postharvest treatment has been implemented, fostering research on suitable alt...
Influence of electron beam irradiation in the organic acids profile of Portugue...
Carocho, Márcio; Antonio, Amilcar L.; Barros, Lillian; Barreira, João C.M.; Bento, Albino; Rafalski, Andrzej; Ferreira, Isabel C.F.R.Organic acids are primary metabolites that play important roles in plant metabolism and confer distinct flavors in fruits. Their consumption is beneficial for humans, namely against certain illnesses. The food industry uses them as preservatives and flavor enhancers. In fruits conservation and transport, organic acids should be preserved at all costs in order to maintain physical quality and pleasant flavors un...
Influence of e-beam postharvest irradiation in the colour of four European ches...
Antonio, Amilcar L.; Carocho, Márcio; Bento, Albino; Rafalski, Andrzej; Quintana, BegoñaIn this study we characterized the physical dimensions of four European chestnut varieties of Castanea sativa, 3 from Portugal (Cota, Longal and Judia) and 1 from Italy (Palummina). The typical physical dimensions of the different chestnut fruit varieties could be used to optimize the process in an irradiation preservation treatment. The chestnut fruits were submitted to an irradiation preservation treatmen wit...
Tocopherols profile of three Castanea sativa varieties submitted to electron be...
Carocho, Márcio; Antonio, Amilcar L.; Rafalski, Andrzej; Bento, Albino; Ferreira, Isabel C.F.R.Chestnuts are widely appreciated fruits all over the world, being China the biggest producer and Portugal standing in fourth place. The Trás-os-Montes region is responsible for 82% of our nation's production [1). Electron beam irradiation has been tested as a postharvest phytosanitary treatment in chestnuts since the main fumigation agent, Methyl Bromide, was banned by the European Union in 2010 due to environm...
