The goal of the research in the Ciftci Lab is green processing of lipids to produce novel food products with improved function and efficacy. Specific research areas include: Particle Formation: Development of green technologies based on supercritical fluid technology to manufacture novel micro- and nanoparticles of bioactive compounds and lipids for improved bioavailability, functionality, and stability. Green Extraction: Extraction of bioactive compounds and lipids from various feedstcoks, including by-products/wastes of agri-food industry, using green methods based on supercritical carbon dioxide and subcritical water. Biorefining: Development of a green biorefinery based on supercritical fluid technology for value-added processing of renewable feedstocks to develop integrated extraction, fractionation, reaction and particle formation of lipids and nutraceuticals as well as investigating the fundamentals. Biocatalytic Conversions: Enzymatic production of structured lipids and industrial products in supercritical fluids. 3D Food Printing: Development of personalized foods via 3D food printing
