Preparation and performance of composite films based on 2-(2-aminoethoxy) ethyl chitosan and cellulose

Abstract

Bioactive films exhibiting antioxidant activity were synthesized from a novel chitosan derivative (AECs) and cellulose under an environmentally friendly process.

Cellulose-Pulp-Based Stretchable Composite Film with Hydroxyethyl Cellulose and Turmeric Powder for Packaging Applications

“…Similar results were observed for microcrystalline cellulose/ agar, microcrystalline/chitosan, bagasse pulp with hemicellulose, bagasse pulp/lignin, and lignin/cellulose/woodbased composites. 3,6,9,10,16,25 Color and UV Spectra. The thickness of the prepared CP composite films was in the range of 0.02−0.04 mm.…”

“…NMMO is a technically feasible solvent, recyclable, and widely used in many different applications. 25 The preparation of polymer blends is an important strategy for converting cellulose into functional materials. 26,27 Hydroxyethylcellulose (HEC) is a common nonionic cellulose derivative; it is biodegradable and biocompatible and has a wide spectrum of applications.…”

“…Further, cellulose is widely used in the medicine and gastronomy fields; it is also used in the manufacturing of household goods. , Cellulose films exhibit good mechanical strength, thermal stability, and stiffness; however, these films exhibit brittle behavior, which limits their application in the packaging industry. Cellulose is an intransigent macromolecule and does not dissolve in common organic solvents and melts; − nevertheless, cellulose dissolves in conventional solvent systems such as NaOH/urea and LiCl/DMA. − However, pretreatment of cellulose is required to attain complete solubility. In our study, we used N -methyl morpholine N -oxide (NMMO) ionic liquids to dissolve CP.…”

“…A cellulose hydrogel with high porosity was obtained using this solvent system; it was physically cross-linked and exhibited high mechanical strength. NMMO is a technically feasible solvent, recyclable, and widely used in many different applications …”

Physical, antioxidant and antimicrobial properties of modified peanut protein isolate based films incorporating thymol

“…7 Because of the requirements of consumers regarding the quality, safety and preservative-free nature of food, active compounds, like antioxidants and/or antimicrobial agents, have been added to edible and biodegradable lms. [8][9][10][11] Some studies have demonstrated that some essential oils and their components, which are extracted from various aromatic plants, have strong antioxidant and antimicrobial properties. [12][13][14] Therefore, they have been incorporated into edible lms to act against foodborne pathogens and increase the shelf-life of food.…”
