Ultrasound-assisted extraction of active compounds of Beta vulgaris
Deep eutectic solvents (DES) are emerging as green and sustainable solvents for the efficient extraction of bioactive compounds and with that have increasingly attracted attention as environmentally friendly alternatives of traditional organic solvents. In this study, aimed to investigate the application of ultrasound in the extraction of betanin from beets (Beta vulgaris) with DES.
Steps to reproduce
The optimization of extraction was performed using the response surface methodology. The time variable was relevant in the performance of the extractions. In this work, three DES Choline chloride: urea (CC:U), Choline chloride: glycerol (CC:G) and Choline chloride: Citric acid (CC: Ac) and were studied.
