Fabrication and characterization of active nanocomposite films loaded with cellulose nanocrystals stabilized Pickering emulsion of clove bud oil.

There is a tremendous increase in the development of alternative food packaging materials which are functional, environment-friendly, and can improve the shelf-life of food products. One such possible approach is to develop biopolymer-based active films loaded with antimicrobial essential oils. In the present study, pearl millet starch (PMS) films reinforced with kudzu cellulose nanocrystals (CNCs) stabilized Pickering emulsions of clove bud oil (CBO) were developed as active and sustainable packaging material.

Pearl millet starch-based nanocomposite films reinforced with Kudzu cellulose nanocrystals and essential oil: Effect on functionality and biodegradability.

This paper documents the preparation of three biopolymer films: 1) pearl millet starch (PMS) films, 2) PMS films reinforced with cellulose nanocrystals (CNCs), and 3) PMS films reinforced with CNCs stabilized Pickering emulsion of clove bud oil (CBO) and a comparison of their mechanical and water barrier properties and biodegradation behavior in soil. Reinforcing PMS films with Kudzu CNCs/CBO significantly increased tensile strength (from 3.9 to 16.

Starch-based bio-nanocomposites films reinforced with cellulosic nanocrystals extracted from Kudzu (Pueraria montana) vine.

In the current study, starch-based active nanocomposite films reinforced with cellulosic nanocrystals (CNCs) of Kudzu were developed as an alternative option to existing biodegradable plastic packaging. Firstly, Kudzu CNCs were prepared by subjecting Kudzu fibers to the processes such as depolymerization followed by bleaching, acid hydrolysis, and mechanical dispersion. Further, nanocomposite films were formulated by blending pearl millet starch (PMS) and glycerol (30%) with different Kudzu CNCs compositions (0-7 wt%) using the solution casting process.
