EOs are an excellent choice to replace petroleum-derived additives in food packaging materials due to their abundance in nature, eco-friendliness, and superior antimicrobial and antioxidant attributes. Thus far, EOs have been used in cellulose-, starch-, chitosan-, and protein-based food packaging materials. Biopolymer-based materials have lower antioxidant and antibacterial properties in comparison with their counterparts, and are not suitable for food packaging applications. Various synthetic-based compounds are being used to improve the antimicrobial and antioxidant properties of biopolymers. However, natural essential oils are sustainable and non-harmful alternatives to synthetic antimicrobial and antioxidant agents for use in biopolymer-derived food packaging materials. The incorporation of EOs into the polymeric matrix affects their physicochemical prop...

Various biopolymers such as alginate, starch, cellulose, chitosan lignin, polylactic acid, and polycaprolactone are elaborately discussed to illustrate the formulation challenges, along with a comprehensive study of their intrinsic properties, processing parameters, and product specifications. It also highlights the formation of tailor-made structures for targeted application in the food industry, consumer products, biomedical field, and aerospace applications. Finally, the chapter presents future perspectives and provides a way to overcome the challenges associated with the 3D printing of biopolymers.

In addition, their use in food packaging applications serve as antioxidants and antimicrobial additive carriers and improve the preservation of food as they can lengthen the shelf life. This chapter focuses primarily on chitin and chitosan-derived composites, and their barrier, mechanical, and thermal properties. Furthermore, the chapter provides the recent advances on chitin and chitosan-derived materials in the food packaging applications. We have also stated our viewpoint about the future of chitin and chitosan-based composites for food packaging applications.

In pharmaceutical industry, the importance of nanocarriers is highly significant. The challenge for targeted delivery is to administer active molecules through different biological barriers, reaching specific targets in an efficient and nontoxic way to release these active substances in a controlled manner. A particular challenge is to develop renewable, biocompatible, and nontoxic nanomaterial, which can effectively incorporate high amounts of drug and its sustained release at the targeted site. Amphiphilic polymeric materials have been extensively exploited as nanocarriers for effective and site-specific targeted delivery. Lipids are generally biodegradable, biocompatible, nontoxic, and nonallergic. Utilization of lipid-derived amphiphiles, which can self-assemble into nanostructures, has shown great potential to solubilize drug in lipid excipients thus giving increased absorption and enhanced bioavailability. This chapter mainly focused on nanoscale amphiphilic polymeric materials and lipid-derived drug delivery systems, their formulations, and applications in the field of biomedical and food industry.

Four different catalysts were screened to carry out rapid reaction at low-temperature in short time span (50 °C and 30 min) and the study demonstrated significant improvements in turnover numbers (TONs) to 92,000 and 78,080 for CO esters and UCO esters respectively, indicating the possibility of convenient scale-up without the requirement for extensive purification of catalysts and starting substrates. A novel renewable lipidic source of spent hen for ethenolysis is exploited for the first time and maximum turnover numbers of 21,820 was achieved through optimization of catalyst/feedstock system.

The block copolymer was synthesized via RAFT polymerization under microwave irradiations. Firstly, the homopolymer of N,N-dimethylacrylamide (DMA) was prepared and used as a macro-CTA to copolymerize with modified stearic acid monomer (SAM). The characterization of copolymer p-DMA-b-SAM was done by (1)H NMR, ATR-FTIR and GPC. The block copolymer was allowed to self-assemble and the entrapment of carbamazepine (CBZ) into hydrophobic core of polymeric micelles was investigated in aqueous media. A high drug entrapment efficiency (69%) was observed for block copolymer micelles. The spherical appearance of micelles in the size range of 20-70nm was determined with transmission electron microscopy (TEM). An effort was also made to investigate the in vitro release profile of CBZ from micelles. A sustained drug release rate was observed, showing complete release of drug within 70h.
