Researchers from Ewha Womans University’s Department of Food Science and Biotechnology and SuFAB Inc., a company based in South Korea, have developed a 3D printing food ink using Auxenochlorella protothecoides to simulate selected fish texture properties. Rheological measurements, printability tests, and texture profile analysis identified a 36% biomass concentration as the only formulation achieving stable extrusion and dimensional accuracy. The study, published in the LWT journal, examines how material composition and printing parameters define a narrow processing window for successful 3D printing. Global seafood consumption has been increasing at nearly twice the rate of population growth, according to the UN Food and Agriculture Organization (FAO), contributing to overfishing, biodive
