Extraction of degraded proteins from red and green macroalgae using ultrasonic-assisted extraction and Fenton's reagent in combination.

ABSTRACT: This study utilized two common macroalgae species from Taiwanese waters, green algae Ulva lactuca (Ulva) and red algae Sarcodia suae (Sarcodia), to evaluate the feasibility and efficacy of a novel cell wall disruption technique combining Fenton reagent and ultrasound-assisted extraction (UAE). The study analyzed protein characteristics, polysaccharide changes, and texture properties after pretreatment. Following cell wall disruption, the combined treatment of Fenton reagent and ultrasound significantly enhanced protein extraction yields, reaching 13.34 ± 0.50 % for Ulva and 3.96 ± 0.28 % for Sarcodia. In addition to increased yields, SDS-PAGE analysis and elevated free amino acid concentrations confirmed extensive protein degradation into low-molec
