ABSTRACT

El aceite esencial de eneldo tiene propiedades antimicrobianas y antifungicas, por lo que puede ser utilizado para evitar el deterioro de los alimentos. En esta investigación se evaluó la capacidad inhibitoria del aceite esencial de eneldo sobre Staphylococcus aureus, coliformes y hongos presentes en la carne de trucha (Oncorhynchus mykiss), utilizando 50 y 100 pL de aceite esencial. Se evaluaron diferentes condiciones de extracción del aceite esencial mediante el método de hidrodestilación y se logró un rendimiento máximo en base seca de 1,32% utilizando una relación 1:5 de agua y material vegetal durante 90 minutos. Al evaluar la capacidad antimicrobiana, el mayor efecto inhibitorio se obtuvo al aplicar 100 pL de aceite esencial de eneldo en cultivos de Staphylococcus aureus, coliformes fecales, coliformes totales y hongos, evidenciándose un mayor halo de inhibición para coliformes totales.


Dill essential oil has antimicrobial and antifungal properties; therefore it can be used in food to avoid deterioration. In this research, the inhibitory capacity of dill essential oil on Staphylococcus aureus, coliforms and fungi present in trout meat (Oncorhynchus mykiss) was evaluated by using 50 and 100 pL of essential oil. In addition, the different conditions of essential oil extraction were evaluated by the hydrodistillation method, yielding a maximum dry basis yield ofl.32%, using a water-plant ratio of 1:5, during 90 minutes. Antimicrobial capacity was evaluated obtaining greater inhibitory effect when applying 100 pL of dill essential oil in cultures of Staphylococcus aureus, fecal coliforms, total coliforms and fungi, evidencing a greater halo of inhibition for total coliforms.
