Chitosan is an attractive biopolymer with great potential to be applied in biomaterial and food packaging fields. However, this natural polymer is only soluble in acidic condition at which the chitosan is highly hydrophilic in nature, thus limiting its widespread application. Here, we report a...

Collagen films have weak wet mechanical properties due to poor water resistance. Herein, two mineralization processes were designed to improve the mechanical properties of collagen fibers under wet conditions for use as packaging materials. One scheme (S1) involved preparing carboxymethyl chitosan...

In line with the growing demand for green alternatives to conventional petroleum-derived plastic packaging, fully bio-based and biodegradable biocomposites were developed for this work, for the purpose of packaging dry foods, following the principles of circular economy. Solutions of plasticized ...

Preventing the precipitation of collagen peptide-fruit juice drinks during production and storage is a current challenge. This study investigated the efficiency and mechanism of β-glucan, low methoxyl pectin, and chitosan (a neutral, anionic, and cationic polysaccharide, respectively) for enhancing ...

Nowadays, food hydrogels are widely applied in food processing and can be utilized to deliver various functional components. Mesona chinensis Benth polysaccharides (MCBP), the major compounds of Mesona chinensis Benth, have been successfully developed as stabilizers, coagulants and binders in the...

Maximizing the waste valorization of renewable resources to develop biocomposite materials is highly desirable regarding environmental sustainability and food chain security. Herein, lignin nanoparticles (LNPs) obtained using deep eutectic solvent (DES) by anti-solvent strategy were employed as...

An amyloid fiber-ferulic acid/chitosan-ferulic acid (AF-FA/CS-FA) double network hydrogel (DN) was synthesized in two steps after prefabricating micronetworks. Ferulic acid (FA) and laccase were used to form protein and polysaccharide micronetworks, respectively. Then, AF-FA and CS-FA were induced...

The aim of this study was to develop intelligent/active packaging by using chitosan/esterified chitin nanofibers (CN) film matrix and anthocyanins from eggplant peel extract (EE) to monitor the freshness of pork. Fourier transform infrared spectroscopy, X-ray diffraction and zeta potential results...

High salt intake is one of the reasons causing dietary risk for death from noncommunicable diseases. In this study, citric acid-crosslinked chitosan (CsC) was prepared using chitosan and citric acid under radio frequency (RF) assisted method, which was considered to absorb Cl- in NaCl and further...

Chitosan based bioactive films incorporated with catechin (CH), quercetin (QDH) and luteolin (LU) at 1, 3, 5 and 10% (w/w of chitosan) were prepared and their biological properties were evaluated. Additionally, the ability of the composite films to improve the shelf life and quality of beef was...
