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 15145 Effects of gama-radiation on white tea volatiles2009 - FANARO, GUSTAVO B.; SILVEIRA, ANA P.M.; NUNES, THAISE C.F.; COSTA, HELBERT S.F.; PURGATTO, EDUARDO; VILLAVICENCIO, ANNA L.C.H.Tea is the second most widely consumed beverages in the world and is processed from two and a bud of Camellia sinensis (L.). Depending on the processing may give rise to four mainly teas (green, black, oolong and white tea). The white tea is the one that has recently awakened interest in scientific community due the fact that this tea has more antioxidant property and activity than green tea. A further industrialization and commercialization of these plants become a problem of public health. The presence of potentially toxigenic fungi can be found in these products, indicating a great potential for the presence of mycotoxins that can cause acute and chronic effects in different organs and systems of the human body. Ionizing radiation is one of the most effective means disinfecting dry food ingredients. This treatment can inhibit cellular life division, like microorganisms, promoting a molecular structural modification. The aim of this study was evaluate the effects of radiation on volatile formation in white tea. Samples were irradiated in room temperature at 60Co source Gammacell 220 (A.E.C. Ltda) at doses of 0, 5, 10, 15 and 20kGy. The volatiles organic compound was extracted by hydrodestilation and the extract was separated and identified by gas chromatography–mass spectrometry (GC–MS) analysis. The results show that the quantities of volatiles formations are directly proportional to the increase of radiation dose. About 37.86% of the compounds were stable at all radiation doses and 47.53% of new compounds were identified after irradiation.Artigo IPEN-doc 15144 Use of electron beam on aflatoxins degradation in coconut agar2009 - ROGOVSCHI, VLADIMIR D.; AQUINO, SIMONE; NUNES, THAISE C.F.; GONCALEZ, EDLAYNE; CORREA, BENEDITO; VILLAVICENCIO, ANNA L.C.H.Artigo IPEN-doc 15143 sup(60)Co Irradiation effect on color in minimally processed cauliflower (Brassica spp)2009 - NUNES, THAISE C.F.; ROGOVSCHI, VLADIMIR D.; SANTILLO, AMANDA G.; MICHELS, ROBERT; PITOMBO, RONALDO N.M.; VILLAVICENCIO, ANNA L.C.H.Artigo IPEN-doc 17046 Effect of ionizing radiation on the texture of minimally processed apples for a fruit salad2011 - FABBRI, ADRIANA D.T.; SAGRETTI, JULIANA M.; ROGOVSCHI, VLADIMIR D.; NUNES, THAISE C.F.; SABATO, SUSY F.
