AI Article Synopsis
- Deep eutectic solvents (DES) are effective for extracting bioactive compounds, specifically anthocyanins, from jaboticaba peels using pressurized liquid extraction (PLE) techniques.
- The optimization process for the extraction involved specific conditions, including a DES concentration of 47%, a temperature of 90 °C, and a flow rate of 5.3 mL/min, resulting in yield improvements up to 50% compared to conventional solvents.
- Analysis indicates that DES solutions yield extracts with better stability and biological activities, making them a promising environmentally friendly method for recovering valuable compounds from plant materials.
Article Abstract
Deep eutectic solvents (DES) are emergent solvents with high extractability of bioactive compounds. Therefore, anthocyanin rich-fractions were recovered from jaboticaba peels by combining aqueous solutions of DES and pressurized liquid extraction (PLE). The extraction occurred at 10 MPa, 12 min, with conditions optimized through response surface methodology: 47% DES concentration, 90 °C, and 5.3 mL/min flow rate. PLE with different DES (choline chloride combined with propylene glycol or malic acid) solutions were compared to conventional solvents (water and acidified water) concerning yield, thermostability, antioxidant, anti-diabetic, and anti-obesity activities. DES solutions presented anthocyanin yields up to 50% higher than conventional solvents. ChCl:Ma, with the highest anthocyanin stability ( = 77.5 kJ.mol), was a promising solvent concerning color, anti-diabetic and anti-obesity potential. Environmental analysis by and indicated PLE with DES solutions is a green and efficient approach to recover anthocyanin from jaboticaba peel, providing useful extracts.
