Research

The research studies carried out in our group are both experimental and computational. The experimental side involves the utilization of (bio)polymers in food nanotechnology applications, especially in packaging and filtration. On the computational side, we perform multi-scale modeling and molecular dynamics simulations of polymeric, bio-molecular and colloidal systems with an emphasis on poorly absorbed lipophilic nutraceuticals.

  • Multiscale modeling and molecular dynamics simulations of polymeric, bio molecular and colloidal systems

Our current efforts are towards expanding the knowledge about the structural properties of duodenal mixed micelles under different physiological conditions and the factors modulating the solubilization of bioactive lipophilic molecules in them via multi-scale molecular dynamics simulations. The structural changes taking place in the dietary mixed micelles upon solubilization of bioactive compounds such as beta-carotene and curcumin, and their interactions with the micelle constituents are among the focuses of our studies. Our motive is that acquisition of such knowledge will facilitate the development of a reverse engineering approach to design more effective delivery systems for lipophilic bioactive components.

Additionally, we comparatively investigate the aqueous behavior of certain monosaccharides through molecular dynamics simulations with a focus on inter- and intra-molecular H-bonding interactions.

  • Food Biopolymers and Nanotechnology Applications
Our group conducts experimental research on multi-layered edible nano-coatings and surface-modified food packaging films. We use layer-by-layer (LbL) assembly to help maintain or extend the shelf life of fresh products. Other interests include encapsulating natural colorants or bioactive compounds. We also fabricate colorimetric pH indicator nanofiber mats by electrospinning for intelligent food packaging applications.
 
Recently, we have shifted our research focus toward investigating biocatalytic electrospun nanofibrous membranes specifically designed for the clarification of juices, exploring their mechanisms and potential benefits in this application. Looking ahead, we aim to explore further applications of these membranes in food processing technologies.
