Nowadays, the need to reduce the dependence on fuel products and to achieve a sustainable development is of special importance due to environmental concerns. Therefore, new alternatives must be sought. In this work, extruded fibers from poly (lactic acid) (PLA) and poly (butylene adipate-co-terephthalate) (PBAT) added with cinnamon essential oil (CEO) were prepared and characterized, and the hydrolytic degradation was assessed. A two-phase system was observed with spherical particles of PBAT embedded in the PLA matrix. The thermal analysis showed partial miscibility between PLA and PBAT. Mechanically, Young’s modulus decreased and the elongation at break increased with the incorporation of PBAT and CEO into the blends. The variation in weight loss for the fibers was below 5% during the period of hydrolytic degradation studied with the most important changes at 37 °C and pH 8.50. From microscopy, the formation of cracks in the fiber surface was evidenced, especially for PLA fibers in alkaline medium at 37 °C. This study shows the importance of the variables that influence the performance of polyester-cinnamon essential oil-based fibers in agro-industrial applications for horticultural product preservation.

Se desarrollaron modelos matemáticos del crecimiento y germinación in vitro de Alternaria alternata en presencia de aceites esenciales. Mediante el análisis de componentes principales, se encontraron similitudes entre ellos considerando su composición volátil. El crecimiento micelial y germinación de conidios de A. alternata se evaluó en PDA con aceites de canela, epazote y limón (0.25, 0.5, 1.0 µL mL-1). Los aceites se obtuvieron por hidrodestilación y comercialmente. Se caracterizaron por cromatografía de gases acoplada a espectrometría de masas. Para ajustar los datos experimentales y predecir su comportamiento se emplearon las ecuaciones de Baranyi y Roberts y logística. Por su composición química los aceites se agruparon en: 1) canela (comercial y no-comercial), en el que predominó el cis-Cinamaldehído, 2) limón comercial (D-Limoneno), y epazote (comercial y no-comercial), con Ascaridol y ρ-Cimeno y 3) limón no-comercial. El aceite de canela (0.5 y 1.0 µL∙ mL-1) inhibió el crecimiento micelial de A. alternata, mientras que, la germinación se inhibió 100 % con la presencia de aceites de limón y epazote (0.25 y 0.5 µL∙ mL-1). Los modelos matemáticos y el análisis de componente principales, son herramientas eficaces para entender el efecto de los aceites esenciales en A. alternata.
