Research Interests
Bioresource engineering including biomass processing, bioprocess engineering, postharvest, sustainable bioenergy systems, and sustainable biometerials.
Research focus on developing efficient and environmentally sensitive methods of producing functional foods, bio-based products and bioenergy from agriculture, agro-process and industrial residues based on green engineering and green chemistry approaches. The specific research areas include:
Biomass processing – biorefineryapproach:
– Advanced lignocellulose fractionation methods for selective extraction of cellulose, hemicelluloses and lignin
– Tailor made fractionation methods to selectively isolate bioproducts and co-products with applications in feed and food processes to improve health and functional properties
– Development of integrated process for production of nano-celluloses and nano-hydrogels from agricultural and industrial wastes
– Synthesis of bioproducts with new functionalities from fractionation products
– Development of new biomass process configurations
– Physical and biochemical modification of structural and functionalities of biomaterials
– Production of soluble and insoluble fibres for functional and health foods.
– Co-production of bioenergy and high value products
Bioprocess engineering:
– Enzyme production and application in biopolymers
– Biomaterial modification and application as additives, entrapment matrices, slow release devices, flour replacers in baking and prebiotics
Sustainable bioenergy systems:
– Systems approach in integrated food and bioenergy systems
– Integration of renewable energy in postharvest technologies, thus, food processing and preservation technologies
– Systems dynamics for tracking and assessing sustainability of flow of bio-resources from agriculture and forestry
