Extraction and Characterization of Gelatin Derived from Acetic Acid-Treated Black Soldier Fly Larvae

•Investigated the potential of black soldier fly larvae (BSFL) as a source of gelatin.•Examined the extraction process of BSFL gelatin with acetic acid pretreatment.•Characterized the physicochemical properties of BSFL gelatin and compared it with commercial porcine gelatin.•Found that BSFL gelatin is heat-stable and has a high melting temperature, rough microstructure, and low foaming properties.•Demonstrated that BSFL gelatin can be used as a novel techno-functional ingredient in the food industry due to its high nutritional value and low cost.
