Abstract

The burgeoning interest in anthocyanins, fueled by their recognized nutraceutical benefits, faces challenges due to the intricate and time-consuming nature of the extraction and purification processes. This study addresses this hurdle by introducing a pioneering method for the simultaneous extraction and purification of anthocyanins from jabuticaba byproducts (Plinia cauliflora). Utilizing a Box-Behnken experimental design, the investigation fine-tuned maceration extraction conditions, pinpointing the optimal combination of time (30 min), temperature (60 degrees C), and solvent composition (50% MeOH v/v), resulting in a yield of 14.43 +/- 0.09 mg g(-1) of anthocyanins. After optimizing extraction conditions, a simultaneous purification step was integrated into the in situ process. The biosorbent from jabuticaba byproducts demonstrated anthocyanin purification from the extract exceeding 90%, outperforming the commercial adsorbent (PoraPak (TM) Rxn) tested. The study unveils an eco-friendly method for anthocyanin extraction with an impressive Ecoscale rating of 86 (maximum of 100). This novel one-step extraction and purification method emphasizes significant anthocyanin recovery while aligning with circular economy principles. It offers notable time and cost savings, enhancing overall production efficiency. (AU)
