Research Interest

Our research program is at the interface of several areas including enzyme technology, food chemistry and nanotechnology. Our research group has expertise in the synthesis of bioactive molecules, modulation of enzyme properties at molecular level, development of efficient nanobiocatalysts and structural analyses.

Our main goal is the development of innovative biocatalytic approaches for (a) the synthesis of well-defined bioactive molecules for use as functional ingredients and nutraceuticals, (b) the structural modification of existing bioactive molecules into suitable functional ingredients and (c) the biogeneration of highly valuable health-promoting ingredients from abundant unexploited by-products.

Current projects, under-investigation in our laboratory, are listed here below.

  • Development of an innovative enzymatic glycosylation strategy based on levansucrase-catalyzed transfructosylation reactions for the synthesis of hetero-fructooligosaccharides and polyfructosides having enhanced prebiotic effects and other physiological properties.
  • Investigation of the synergetic actions of levansucrase and fructanase for the enrichment of maple products with controlled-molecular-size β-(2-6)-fructooligosaccharides with high colonic persistent prebiotic activity.
  • Exploration of the properties of selected biocatalysts immobilized on nanoparticles in a little-explored transitional region between heterogeneous and homogeneous catalysis.
  • The regioselective acylation of oligosaccharides with phenolic acids by feruloyl esterase using nano-emulsion systems to produce phenolated oligosaccharides.
  • Modulation and optimization of the glycation of selected proteins (lysozyme, Potato Proteins) with mono-, oligo- and polysaccharides to improve their physico-chemical and functional properties.
  • Development of innovative biocatalytic approaches for the biogeneration of polysaccharides, proteins and non-digestible oligosaccharides from potato by-products.

The results of these projects have implications in various fields as biotechnology, food science, industrial processing and pharmaceutical science.
