This study investigates the ultrasound-assisted extraction of bioactive compounds, particularly tannins, from potato peel, a widely available agricultural by-product. The optimization of extraction parameters, including solvent type (water, methanol, ethanol, acetone) and extraction time (10 and 15 minutes), was carried out to maximize the yield of phenolic compounds and tannins. The results showed that water was the most effective solvent for both phenolic and tannin extraction, with the highest yields obtained at 15 minutes. Specifically, 219.5 ± 75.4 mg of phenolic compounds and 142.83 ± 9.50 mg of tannins per 100g of dry potato peel were recovered using water. The optimization of these extraction parameters was confirmed through statistical analysis, including ANOVA, which revealed significant effects of both solvent type and extraction time on the extraction efficiency (P<0.01). The ultrasound-assisted extraction method proved to be an efficient, sustainable, and cost-effective technique, demonstrating its potential for industrial-scale applications, particularly in the food, pharmaceutical, and cosmetic industries. This study offers a promising approach to valorize potato peel waste, contributing to both waste reduction and the production of valuable bioactive compounds.
