Item The determinants of export behaviour: a study of food processing industry in India(Inderscience Publishers, 2022) Gr, G.R.; Bhat, S.The study examines the factors that determine the export behaviour of food processing firms operating in India based on data from the Centre for Monitoring Indian Economy (CMIE) Prowess Database for 2011–2016. It examines the effect of three technological variables on the export behaviour of firms: information and communication technology (ICT) investment, in-house research and development (R&D), and the import of embodied technologies. Further, it tries to understand if the technological activities of affiliated firms have any effect on their export performance. Using the Heckman two-step sample selection analysis, it reveals that technology investments are important determinants for the export behaviour of firms. Other control variables like firm size, firm age, and the capital–labour ratio were also found to be important in determining the export behaviour of food processing firms. The study gives policy suggestions for improving the global competitiveness of firms in this industry. © © 2022 Inderscience Enterprises Ltd.Item Development of hybrid chitosan/zinc oxide/graphene oxide nanocomposites for potential food packaging application(Sustainable Building Research Center, 2023) Kanted, D.; Soman, V.; Sahota, S.; Poddar, M.K.Novel food packaging materials are becoming increasingly necessary and extensive research is underway worldwide towards developing environmentally friendly and bio-based polymers. Among various biopolymers, chitosan is the noticeable and industrially viable food packaging material and is the second most naturally available biopolymer after cellulose. This study is based on the reinforcing hybrid nanomaterials of zinc and graphene oxides into the chitosan matrix to produce a bio-based food packaging material with improved antimicrobial properties, high water resistance and thermally stable hybrid chitosan/ZnO/GO nanocomposites. Various characterization techniques such as Raman, FTIR, XRD and FE-SEM confirmed the preparation of nanofillers and their successful encapsulation into the chitosan matrix. The thermal analysis results confirmed a marked rise of 46.5 and 62.1°C at T25% and T50% respectively of hybrid nanocomposites as compared to neat chitosan. Further, the DTG analysis showed there was a significant rise of 19°C in the maximum degradation temperature for hybrid chitosan/ZnO/GO nanocomposites as compared to neat chitosan. The water vapor permeability of hybrid nanocomposites was reported at a minimum of 1.04 g.mm/m2.h.kPa against the neat chitosan of 2.22 g.mm/m2.h.kPa which confirmed the nanocomposites with improved water resistance. The antimicrobial property tested in presence of Bacillus subtilis (gram-positive bacterium) was reported maximum for hybrid chitosan/ZnO/GO nanocomposites with the highest inhibition zone of 12 mm as compared to the inhibition zone of neat chitosan, chitosan/GO, and chitosan/ZnO of 5 and 10 mm respectively. The increase in the above properties of the hybrid nanocomposites is attributed to the combined effect of hybrid nanofillers as compared to the nanocomposites with the use of single nanofillers. © International Journal of Sustainable Building Technology and Urban Development.
