Physicochemical Characterization and Antioxidant Activity of Semi-Refined Carrageenan Extracted from Kappaphycus alvarezii

Semi-refined carrageenan (SRC) is a lower-processing alternative to refined carrageenan that retains part of the native seaweed matrix. This study characterized SRC extracted from Kappaphycus alvarezii using alkaline pretreatment followed by ultrasound-assisted extraction (UAE). Extraction temperature was varied from...
