Pineapple (Ananas comosus) processing generates significant agro-industrial waste, mainly peels, accounting for up to 50% of the fruit [1]. These residues may contain more bioactive compounds than the edible portion [3,4]. This study evaluated the effect of solvent (70% methanol and acetone) and peel condition (fresh and dried) in two pineapple varieties [2,5]. Ultrasound-assisted extraction was applied. Dried peels extracted with acetone showed the highest phenolic content and antioxidant activity in the INDIA variety. IR-ATR analysis confirmed functional groups associated with phenolic structures, highlighting the potential for sustainable valorization of these by-products.
