Supramolecular solvent extraction of bioactive compounds from tamarillo (Solanum betaceum) byproducts

Abstract

Purpose: This study used the eco-friendly SUPRAS extraction technique to recover total phenolic compounds (TPC) and carotenoids from tamarillo byproducts, overcoming the limitations of traditional solvent extraction. Methods: In situ extraction with SUPRAS was conducted using two amphiphiles (decanoic acid DA and octanoic acid OA), ethanol, and water. SUPRAS composition was optimized considering the TPC and AA. Results: TP exhibited higher TPC, carotenoids, and AA compared to the seed and pulp. The optimal conditions for SUPRAS were: 7.7% DA, 33% ethanol, and 59.3% water, and 8.8% OA, 22% ethanol, and 69.2% water. At these synthesis conditions, TPC were 0.14 and 0.19 gGAE/100 g; 73 and 72% for DPPH scavenging, and 151 and 147 μM TEAC for decanoic acid and octanoic acid-based SUPRAS respectively. The OA increased TPC extraction slightly, while the AA showed the opposite effect. Conclusion: SUPRAS demonstrated higher extraction of TPC and AA compared to organic solvents. SUPRAS shows high potential for the extraction of bioactive compounds.
