On December 20, 2023, Senior Research Fellow of the laboratory «Chemistry and Marine Bioresources Technology», Associate Professor of MAU Department of Chemistry, Nikolay Voronko was granted academic degree of Advanced Doctor of Chemical Sciences.
His thesis on the topic «Hydrogels based on of gelatin-polysaccharide complexes and their role in the creation of innovative food products» was completed with the guidance of Svetlana Derkach, Advanced Doctor of Chemical Sciences. Nikolay Voronko defended his thesis in MIREA — Russian Technological University in Moscow on June 29, 2023.
As Nikolay said, the goal of his work was to research the properties of supramolecular gelatin-polysaccharide complexes of different chemical structure that are used in creating sustainable high concentrated emulsions and hydrogels with the required physical and chemical features.
«The demand for protein-polysaccharide systems based hydrogels used in food production processes, as well as new artificial forms, is high and requires development of fundamental knowledge in this sphere that would ensure technological safety,» noted Nikolay Voronko. «Another goal of the research is expansion of raw material base in food industry that uses bioresources of Russian Arctic. The use of gelatin and polysaccharides obtained from aquatic organisms and their recycling byproducts helps develop biological resources.»
In the thesis, Nikolay suggested a way of advancing fish oils encapsulation technology using enduring and fast in structure formation gelatin-polysaccharide hydrogels. The scientist also gave recommendations for the use of gelatin as a component of gelling additive based on an essence of alginate-containing brown algae Fucus vesiculosus in food containing fish proteins. Within the concept of sound use of marine bioresources of the Russian Arctic, the chemist developed methods of using cold-water fish skin gelatin as alternative to mammalian gelatin.
