A beterraba vermelha (variedade hortícola, cultivar Early Wonder) foi cultivada na área experimental do Departamento de Fitotecnia do Instituto de Agronomia da Universidade Federal Rural do Rio de Janeiro. Após a colheita, as raízes foram minimamente processadas, embaladas e submetidas a diferentes doses de radiação gama (0; 0,5; 1,0; e 1,5 kGy), sendo em seguida armazenadas, por 20 dias, a 8 °C. Durante o período de armazenamento, aos: 1, 9, 13 e 20 dias, foram realizados testes sensoriais, nos quais 12 avaliadores julgaram a aparência e o aroma segundo uma escala hedônica. Os resultados indicaram que as amostras irradiadas com doses de 1,0 e 1,5 kGy mantiveram-se dentro dos padrões de aceitabilidade por 20 dias. Alem disso, foi também observado que a avaliação do aroma permitiu uma melhor discriminação, dos efeitos das diferentes doses de radiação sobre a aceitação do produto. Palavras-chave: processamento mínimo; irradiação de alimentos; extensão da vida útil; qualidade sensorial; aroma. AbstractRed beet (Early Wonder) was cultivated in an experimental area of the Department of Fitotecnia at the Institute of Agronomy at the Rural Federal University of Rio de Janeiro (UFRRJ). After harvest, the roots were minimally processed; packed; exposed to different doses of gamma radiation (0; 0.5; 1.0 and 1.5 kGy) and stored for 20 days at 8.0 °C. Sensory evaluations were performed 1; 9; 13 and 20 days after irradiation by 12 testers who rated the overall appearance and aroma on a hedonic scale. The results indicated that the irradiated samples remained within the limit of acceptance for 20 days. In addition, the aroma was found to be a more sensitive indicator of the effect of different doses of radiation to the acceptance of the product.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
