“…Additionally, the modified chitosan-based composite possessed significant antibacterial and antioxidant ctivity compared to basic chitosan [ 196 ]. Polyethylene (PE) and polypropylene (PP) two-layer functional coated films were developed for the active packaging using macromolecular chitosan solution for first, while the second (upper) layer contained catechin and pomegranate extracts (polyphenols) incorporated in chitosan nanoparticles with the aim to provide an antioxidant and antimicrobial properties of food packaging [ 197 ]. Ag nanoparticles/chitosan/PVA electrospun fibrous composite nano-layers were successfully used as packaging material for meat with improved bio-activity and extended meat shelf life [ 198 ].…”

Background: Bionanotechnology, as a tool for incorporation of biological molecules into nanoartifacts, is gaining more and more importance in the field of food packaging. It offers an advanced expectation of food packaging that can ensure longer shelf life of products and safer packaging with improved food quality and traceability. Scope and approach: This review recent focuses on advances in food nanopackaging, including bio-based, improved, active, and smart packaging. Special emphasis is placed on bio-based packaging, including biodegradable packaging and biocompatible packaging, which presents an alternative to most commonly used non-degradable polymer materials. Safety and environmental concerns of (bio)nanotechnology implementation in food packaging were also discussed including new EU directives. Conclusions: The use of nanoparticles and nanocomposites in food packaging increases the mechanical strength and properties of the water and oxygen barrier of packaging and may provide other benefits such as antimicrobial activity and light-blocking properties. Concerns about the migration of nanoparticles from packaging to food have been expressed, but migration tests and risk assessment are unclear. Presumed toxicity, lack of additional data from clinical trials and risk assessment studies limit the use of nanomaterials in the food packaging sector. Therefore, an assessment of benefits and risks must be defined.

“…2 Chitosan (CS) is the second most abundant polysaccharide after cellulose, which has good biocompatibility, high oxygen resistance and film-forming properties. CS is a cationic linear polymer, which is composed of poly poly(β- [1][2][3][4]-N-acetyl-D-glucosamine) obtained by partial deacetylation of chitin. Chitin is widely distributed in the crustacean shells of shrimp, crab, insect and the cell walls of fungi.…”

“…Chitin is widely distributed in the crustacean shells of shrimp, crab, insect and the cell walls of fungi. 3 Moreover, CS is easy to inhibit the growth and reproduction of bacteria and fungi by electrostatic action because of its hydroxyl group. 4 Therefore, it is an ideal choice for active food packaging applications.…”

In order to solve the problems of traditional plastic packaging materials like poor degradability and insufficient active packaging function, this study successfully designs and synthesizes tannic acid (TA)-titanium (Ti) dual network coated hydrotalcite-like layered clay (LDHs@TA-Ti) and catechol grafted chitosan (C-CS) based on the principle of mussel bionics. And a novel idea is first put forward to fabricate LDHs@TA-Ti/C-CS/polyvinyl alcohol (PVA) nanocomposite films by solution casting method. The result of infrared and thermal analysis indicate that strong interfacial interaction is formed in the nanocomposites, which leads to the limitation of molecular chain movement and the increase of glass transition temperature. Although the addition of LDHs@TA-Ti significantly increases the crystallization temperature, the crystallinity does not change significantly. The water resistance, UV barrier, tensile strength and antibacterial properties of the final nanocomposite films are improved significantly, and all the films show good transparency in the visible range. Especially when the addition amount of LDHs@TA-Ti reaches 1 wt%, compared with C-CS/PVA composite film, the UV (at 300 nm) barrier property and tensile strength are increased by 36.3% and 45.1% respectively. Therefore, LDHs@TA-Ti/C-CS/PVA nanocomposite films show great potential as environmentally friendly active packaging films or coatings in extending the shelf life of food products.

The aim of the recent study was to assess the extent of catechin hydrate release from newly synthesized bioflavanol-loaded chitosan-based particles. The biopolymer particles were prepared by a modified ion gelation method. The synthesized biopolymer particles were divided into two series: Series 1 -washed with ethanol and stored in 70% EtOH at 4 o C, and Series 2 -washed with EtOH, dried and stored at -18 o C. Both particle series were stable after 72 h storage. The desorption experiments were conducted by agitation of determined mass of catechin-loaded particles in PBS for 48 h. The maximum efficiency of catechin desorption from series 1 particles in PBS was 91% in simulated intestinal medium after 48 h. Series 2 catechin-loaded particles exhibited slightly higher desorption extend in PBS. It has to be outlined that the size of series 1 particles significantly decreased, while the dried particles were completely degraded at the end of the experiment.
