Supercritical fluid extraction of coumarins and flavonoids from citrus peel
The production manufacture of juices generates a large amount of waste consisting mainly of fruit peels. The peels are source of molecules such as coumarins and flavonoids. In this study, the peels of Citrus limonia, Citrus deliciosa, Citrus latifolia and Citrus sinensis were the raw material for supercritical fluid extraction. The Box-Behnken design was used to optimize the global yield in function of process variables. The chemical analysis of the extract was carried out by LC-MS and GC-MS. CFD was applied to the mass and momentum conservation equations in the study of supercritical extraction using citrus peels, which allowed the determination of unknown parameters of the bidimensional mathematical model. The flavonoids, nobiletin, sinensetin and tangeretin, as well as the coumarin, citropten, were identified in all species investigated. The maximum global yield obtained were 3.93 % for Citrus limonia, 4.18 % for Citrus deliciosa, 3.48 % for Citrus latifolia and 5.32 % for Citrus sinensis.
期刊介绍:
The Journal of Supercritical Fluids is an international journal devoted to the fundamental and applied aspects of supercritical fluids and processes. Its aim is to provide a focused platform for academic and industrial researchers to report their findings and to have ready access to the advances in this rapidly growing field. Its coverage is multidisciplinary and includes both basic and applied topics.
Thermodynamics and phase equilibria, reaction kinetics and rate processes, thermal and transport properties, and all topics related to processing such as separations (extraction, fractionation, purification, chromatography) nucleation and impregnation are within the scope. Accounts of specific engineering applications such as those encountered in food, fuel, natural products, minerals, pharmaceuticals and polymer industries are included. Topics related to high pressure equipment design, analytical techniques, sensors, and process control methodologies are also within the scope of the journal.
