Abstract
The peach palm can be obtained from several species of palms, but the peach palm has attracted great interest by producers, as has characteristics of precocity, rusticity and tillering, producing a palm-quality differentiating it from other palmettos for their sweet flavor and yellowish . The food irradiation has been used as a treatment to ensure microbiological food safety of products to avoid infection. Its use combined with minimal processing could increase the safety and quality of minimally processed vegetables. We aimed at evaluating the effect of gamma radiation and electron beams to control bacteria; assess the physical characteristics through analysis of color and texture in peach palm in natura minimally processed and subjected to ionizing radiation stored at 8 deg C as well as evaluating the sensory characteristics. The results in the microbiological analysis showed that ionizing radiation promotes reduction of microbial load in both treatments. In the analysis of color we can conclude that among all the treatments the sample irradiated with 1.5 kGy showed more differences when compared with the other samples. Observing texture characteristics we could conclude that irradiation changed the texture of the palm, unlike the treatment by electron beams that showed no difference between samples.

For the sensory analysis, the gamma radiation with dose of 1.5 kGy, induced changes in sensory properties to the attributes and overall appearance. The dose of 1 kGy caused no significant difference, so a recommended dose for the irradiation of the studied product. (author)}
