- Evaluation of potential of gamma radiation as a conservation treatment for blackberry fruitsPublication . Oliveira, Marina; Pinto, Maria PaulaBlackberries consumption has been associated with health benefits; however, these fruits are quite perishable. The objective of this study consists in analyse the potentiality of gamma radiation as a decontamination method for blackberry fruits. Fresh blackberries were irradiated in a 60Co at different doses (0.7 kGy up to 2.6 kGy) and microbiological, physicals, chemicals and sensorial parameters were assessed immediately after irradiation and at after two, and three and seven days of storage time at 4ºC, for first and second sampling, respectively. The microbial inactivation efficiency on blackberries ranged between 48% and 99% for gamma radiation doses ≥ 1 kGy. Moreover, the applied irradiation doses do not result in a major impact on the physical, chemical and sensory attributes of blackberries. This work shows that treatment with gamma radiation has a high potential to be evaluated as a treatment for conservation of blackberries.
