Advances between e-beams and sup(60)Co applications in soybeam grains

Abstract

Soybean is the most important oleaginous cultivated in the whole world and generates income of billions of dollar, direct and indirectly and its nutrients become basic for the feeding human being, beyond its byproducts, that offer great diversities of products for the nourishing industry. Between the main factors that limit the attainment of high incomes, are the illnesses caused by microrganism like fungi, bacteria, and viruses that, in general, are difficult to control and cause damages of billions of dollar every year. An alternative to minimize the losses is preserving the grains through the irradiation and then, the use of electron accelerator is indicated, therefore its advantage for exporting industria of grains in relation to the irradiators for 60Co is basic. This work aims to compare the effects of the radiation through viscosimetry, DNA Comet Assay and Cooking time techniques in soybean grains at doses 0, 2.0, 4.0, 6.0kGy irradiated at e-beam accelerator - Radiation Dynamics (Radiation Dinamics Co. model JOB, New York, USA), 1.5 MeV-25mA with the lower energy and in a 60Co source, Gammacell 220 (A.E.C. Ltda) in ambient temperature.
