ROORKEE: Polymer scientists at IIT-Roorkee have claimed to have developed an indigenous know-how to develop “bio-based” packaging (color) supplies. They mentioned with using their know-how, making counterfeit packaging of any product can be extremely troublesome.
A peer-reviewed scientific journal — ACS Applied Nano Materials — has revealed their examine in its latest concern. To fulfill their goal of a bio-based know-how, researchers used bagasse (agro-waste sugarcane) and natural acids (OAs) like citric, malic and tartaric acids, and many others, after extracting from orange, apple and tamarind.
“Till now, the provision of barcodes is being made available by the packaging industry of any product to stop the counterfeit practices. However, barcodes can also be counterfeited. But our technology is secured from counterfeit as our packaging sensors (colour materials) are transparent in nature and can only be detected after use of UV light. A market-available UV torchlight will be helpful in detecting the colour (as a code) on a strip pasted on the packaging wrappers,” mentioned Pradip Ok Maji, principal investigator of the undertaking.
The different researchers related to the undertaking have been Chhavi Verma, Saurabh Ok Kardam, Monika Chhajed and Upendranath Nandi. According to Chhavi Verma, they obtained cellulose nanocrystal (CNC) movies from bagasse and added layers of various OAs underneath many phases of laboratory course of. By this they acquired versatile and clear movies that displayed good visible colour-sensing properties with average anti-bacterial exercise for Escherichia coli micro organism. “This process is divided into stages of bleaching raw fibre and acid hydrolysis of cellulose pulp under standardized conditions. The final CNC suspension is then concentrated to make it behave as a liquid crystal material showing birefringence (splitting of light) properties,” she added.
The CNC of bagasse has an inherent high quality of colors however that can not be seen with a unadorned eye. Researchers obtained the specified color by way of “modification techniques” of biopolymers after including OAs in layer by layer meeting.
