Avances en la aplicación de luz ultravioleta de onda corta (UVC) en frutas y vegetales enteros y mínimamente procesados: revisión

Juan Pablo Pablo Quintero Cerón, Yanneth Bohorquez Pérez, Claudia Valenzuela Real, José Fernando Solanilla Duque

Resumen


En vista del impacto que conlleva la carga microbiana contaminante sobre la superficie de los productos hortofrutícolas, los investigadores y la industria han centrado su interés en el estudio y aplicaciones de la radiación ultravioleta de onda corta por su efecto deletéreo sobre fitopatógenos, relativo bajo costo, versatilidad y nula residualidad. Recientes hallazgos han dado a conocer que esta radiación no ionizante actúa como un elicitor que a bajas dosis estimula la expresión de genes involucrados con respuestas fotomorfogénicas encargadas de promover la resiliencia del tejido. Teniendo en cuenta lo manifestado, el presente artículo recoge variados y recientes estudios donde se analizan las respuestas de diversos productos hortofrutícolas frescos y mínimamente procesados a tratamientos fotoquímicos (UVC), sus limitaciones, beneficios y efectos adversos.
