Extracción de clorofilas a partir de subproductos de Solanum lycopersicum var. cerasiforme

Abstract

La industria alimentaria tiene un gran interés en el uso de residuos y subproductos para el desarrollo de colorantes naturales con propriedades bioactivas. Como pigmentos naturales más abundantes en las plantas, las clorofilas tienen un gran potencial de aplicación en este sector. En el presente estudio, se realizaron dos tipos de extracción a partir de las partes aéreas de tomate, con el fin de maximizar el rendimiento de extracción de las clorofilas. Para esto, se variaron los parámetros involucrados en cada método de extracción: en la maceración, el tiempo de extracción y el solvente, y en la extracción asistida por ultrasonidos, la potencia y el solvente. Por otro lado, para priorizar los procesos amigables con el medio ambiente, se utilizaron los solventes verdes etanol y hexano. La identificación y cuantificación de los compuestos clorofílicos se efectuó por HPLC-DAD/ESI-MS. En general, las partes aéreas de tomate revelaron concentraciones considerables de clorofilas y derivados, hasta 211,6±0,3 μg/g. La técnica de ultrasonidos fue más eficaz que la maceración y en comparación con el hexano, el etanol permitió un rendimiento de extracción 100 veces mayor. Este estudio puede servir de base para futuras investigaciones en la extracción de clorofilas con alta capacidad colorante.
