Fish skin is in collagen (80-90%). However, catfish (Pangasius sp.) skin has a high lipid content which can reduce the quality of collagen. Therefore, treatment is needed to remove the lipid using ultrasonic assisted extraction (UAE) with ethanol. Hence, the aim of present study was to remove lipid content from catfish skin as a raw material of collagen by using UAE with different concentrations of ethanol (25, 50, 75%). The research was conducted in three stages: removing impurities, collagen extraction and characterization of collagen. The result exhibited that UAE-ethanol treatment was capable to remove up to 85.6% of lipid content and the produced collagen was potential to be utilized as an alternative source of collagen based on its properties. © 2024 Faculty of Fisheries and Marine Universitas Airlangga.
