Encapsulation of olive leaf (Olea europaea) extract using solution-enhanced dispersion by supercritical fluids (SEDS) technique
Olive leaves are considered a byproduct or agroindustry waste, although they contain several bioactive compounds. The objective of this work was to encapsulate olive leaf extract in poly(3-hydroxybutyrate-co-3-hydroxyvalerate) PHBV using the SEDS technique using supercritical CO2 as an antisolvent. The materials were characterized by DSC, SEM, and FTIR, and the stability (antioxidant activity, total phenolic, and total flavonoid) was monitored over time. The highest encapsulation efficiency (EE) was 86.0%. The mean particle size changed from 0.30 to 0.71 µm depending on the experimental condition. The generated particles remained stable about the residual contents of total phenolic and flavonoids in the encapsulated extract, with values greater than 70% on the 210th day. SEDS proved to be an efficient and reliable technique for the encapsulation of active olive leaf compounds in PHBV.
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.
