Research Areas

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 feedstocks, 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
