Resumo IPEN-doc 17452 E-beam irradiation of "in Natura" Palm: texture and color evaluation2009 - SILVA, P.V.; NUNES, T.C.; FURGERI, C.; VILLAVICENCIO, A.L.C.H.Artigo IPEN-doc 15149 Microbiological analysis of peach palm in natura submitted to sup(60)CO radiation2009 - SILVA, PRISCILA V.; ARAUJO, MICHEL M.; NUNES, THAISE C.F.; COSTA, HELBERT S.F.; HOJEIJE, KHALIL Y.; VILLAVICENCIO, ANNA L.C.H.The palm tree (Bactris gasipaes Kunth) is a species with high potential benefits, because of the nutritional value of its fruits that could be used both in human and animals feeding and mainly for peach palm extraction. It represents a great source of dietary fiber and a moderate source of magnesium and iron. Food irradiation is a worldwide technology that aims to improve the product quality, in order to eliminate diverse microorganisms that can spoil the food. Radiation processing, in the recommended doses, causes very few chemical alterations and nutritional losses in foods, being considered insignificant and/or similar to other food treatments. The objective of this study was to evaluate the effect of irradiation on microbiological counts of mesophilic aerobic in the peach palm in natura. Samples were irradiated with 1.0 and 1.5kGy using a 60Co multipurpose irradiator. Radiation treatment appeared to be a useful alternative to reduce microbial contamination in the samples analyzed.Artigo IPEN-doc 12686 Effects of electron beam treatment in soybean grains artificially inoculated by Phakopsora pachyrhizi2007 - FANARO, G.B.; SILVA, P.V.; NUNES, T.C.F.; ROGOVSCHI, V.D.; AQUINO, S.; VILLAVICENCIO, A.L.C.H.Interactions between plants and pathogenic fungi have always been of extreme interest to humanity, since the worldwide economy is built around the purchase and sale of species vegetables among countries, who can suffer serious damages by pathogenic organisms contamination. Soybean is the most important culture of grains in Brazil, which is the second biggest exporter of this grain and suffers from the attack of the fungi Phakopsora pachyrhizi that causes the Asian Soybean Rust. The infection for P. pachyrhizi causes fast blackout and the premature fall of leaves, hindering the full formation of them. The technology of irradiation processing for nutritive purposes is a process that is safe and effective for reducing the microbial load, insect infestation, and extending the shelf life of perishable products. This study aims to verify the artificially inoculated soybeans behavior when treated by electron beam from a linear accelerator at different radiation doses while observing whether the fungi population was reduced or not. The grains of soybean were irradiated at IPEN-CNEN/SP in an electron accelerator of Radiation Dynamics Inc. USA, 1.5 MeV-25mA at doses 0; 1.0; 2.5; 5.0; 7.5 and 10.0 kGy.
