Influences of the GAMMA radiation on useful life of strawberry

The present investigation was carried out with the purpose of prolonging the useful life of strawberry (bird variety) by means of gamma radiation, eliminating the causing microorganisms of the deterioration of the fruit partially: aerobic mesophyll, psicrotrophos, molds and yeasts, effect that was controlled by means of the recount of the same ones. In the same way, it was carried out a quantitative analysis of some parameters such organolitics as flavor, color and hardness, to observe the behavior of the strawberry with the different applied treatments. The irradiation process was made with a source of Co-60, provided by the INEA with an activity of 82 kilo curios. The used radiation doses were 0, 1.0, 1.5, 2.0, 2.5 and 3.0 kGy, which were quantified by means of chemical dosimeter : Sulfate cupric ferrous-sulfate. Strawberries were storage under refrigeration with controlled conditions of temperature between 1 and 2 C and relative humidity of 85-90, and periodically, samples were removed for different analyses
