Played an important role in development and evaluation of solar-operated Fruit and vegetable vending van suitable for retail sale and short distance transportation of fresh fruits and vegetables; Evaporative cooled rooms (ECRs) for extending the storability of fresh fruits and beverages and Arka High Humidity storage boxes for green leafies and other vegetables for quality parameters. Isolated, screened and developed microbial isolates capable of producing functionally active multi-component cellulases and hemicellulases in significant concentrations and multi-stress tolerant microbial strains which play a significant role in bioconversion and bioprocessing. Optimized processes for production of value added products such as nutraceutical beverage, face care systems, candies and enzymes from Kinnow by-products. Instrumental in development of value-added products, such as Kokum Amla (rich in malic acid, hydroxycitric acid, anthocyanins, vitamin C) and osmo-dried guava slices. Appraised antioxidant potential for various fruit and vegetable residues and also established a commercial use for such residues. Played an important role in optimizing the process for production of xylo-oligosaccharides from agro-residues using thermostable enzymes from thermophilic fungal strain and separation of such compounds through nanofiltration. Designed and developed biomass extruder, integrated pilot plant combining pretreatment, hydrolysis and fermentation and also hydrolysis assembly for production of sugars from crop residues and processing by-products. Instrumental in design, development and establishment of the pilot plant for processing of red and green chillies at ICAR-CIPHET. Ludhiana.
