Optimization of Ultrasound-Assisted Extraction and Encapsulation of Antioxidants from Orange Peels in Alginate-Chitosan Microparticles.

The recovery of bioactive compounds from waste and modification of their properties by encapsulation are the main challenges today. In this study, the ultrasound-assisted extraction of antioxidants from orange peels was optimized using a central composite design. Ethanol (50%, /) was the solvent of choice for their extraction.

Optimization of Ultrasound-Assisted Extraction of Phenolic Compounds from Black Locust () Flowers and Comparison with Conventional Methods.

The aim of this study was to optimize the ultrasound-assisted extraction of phenolic compounds from black locust () flowers using central composite design. The ethanol concentration (33-67%), extraction temperature (33-67 °C), and extraction time (17-33 min) were analyzed as the factors that impact the total phenolic content. The liquid-to-solid ratio of 10 cm g was the same during extractions.
