Resumo
Ionizing radiation applied to agriculture has mainly benefited food production, as it reduces
natural losses caused by physiological processes, as well as eliminating or reducing
microorganisms, parasites and pests. In addition, this technique also allows the production of
mutants with characteristics of greater productivity, precocity, smaller size, greater resistance
to diseases and pests. These mutants are used to obtain new varieties of species of agronomic
interest. The objective of this study was to evaluate the physic-chemical quality of the oil
extracted from seeds of G. max (soybean) obtained from irradiated seeds with different doses
of gamma radiation (0, 25, 50, 75 and 100 Gy of a Cobalt-60 source, type Gammacell-220
installed in CENA-USP). The physic-chemical analyzes included: AOCS Cd-3d-63, AOCS
Cd-3-25 and AOCS Cd-1-25, Acids Index (I.A), Saponification Index (IS), Iodide Index (II),
respectively. All analytical determinations were performed at least in triplicates. The values
found for I.A., for I.S. and for I.I., did not differ from the oil sample obtained from soybean
seeds from control subjects (without irradiation) regardless of the concentration and dose of
radiation applied to the seeds. The oil analyzed did not show physical-chemical variation in
comparison with the oil obtained from non-irradiated seeds, thus suggesting the absence of
modifications in these parameters after the genetic improvement induced by the radiation.
