Influencia del encerado en la calidad de la mandarina Clemenules procedentes de Sistemas de Producción Integrada Jose Ma. Martínez Jávega I. Cáceres J. Cuquerella M. A. Río del P. Navarro Agrociencias madurez cítricos postcosecha deórdenes fisiológicos desórdenes patológicos En la Post-cosecha de frutas el uso de ceras puede considerarse una buena alternativa para controlar las pérdidasde calidad, desórdenes fisiológicos y patológicos. En el presente trabajo se estudia el comportamiento de frutasde mandarina «Clemenules» de «Sistema de Producción Integrada» tratadas con ceras de polietileno, abeja,candelilla, carnauba y estas formulaciones más goma laca. Las frutas se almacenaron a bajas temperaturasdurante 2 semanas más 1 semana a 20 °C. Se determinaron los cambios de los parámetros de calidad de lasfrutas (peso, firmeza, índice de madurez, brillo, volátiles en jugo, sabor y comestibilidad y alteraciones fisiológicas).Los resultados muestran que el encerado reduce la transpiración de las frutas durante el almacenamiento ycomercialización (20°C). El contenido de etanol y acetaldehído se incrementó, aunque no se produjeron malossabores con ninguna de las ceras aplicadas. En ningún caso se detectaron alteraciones fisiológicas y pudriciones.El índice de madurez se mantuvo estable en todos los tratamientos. Las formulaciones de ceras naturales (abeja,candelilla y carnauba) con 2% de goma laca resultaron tan eficaces para el mantenimiento de la calidad como laconvencional de polietileno más goma laca. Las frutas de «Producción Integrada», las cuales tienen normativaso limitaciones en cuanto a la utilización de productos químicos manifestaron buena calidad durante la postcosecha 2003 artículo científico 1665-0204 https://www.redalyc.org/articulo.oa?id=81350207 es http://www.redalyc.org/revista.oa?id=813 Revista Iberoamericana de Tecnología Postcosecha application/pdf Asociación Iberoamericana de Tecnología Postcosecha, S.C.
