“…The FT-IR spectra of CS and CS-phenolic acid derivatives are shown in Figure 2A. CS has a strong absorption band at about 3400 cm -1 attributable to O-H and N-H stretching, with absorption bands at 1658, 1590, and 1323cm -1 , respectively, for C=O stretching of residual N-acetyl groups (amide I), N-H bending (amide II), and C-N stretching (amide III), typical of the amide bond of several peaks, the 1590 cm -1 band corresponds to the N-H bending of the primary amine (Lian et al, 2022). At 1421 cm -1 and 1379 cm -1 can be attributed to CH 2 bending and CH 3 symmetric deformation, respectively.…”

In this study, we incorporated gallic acid (GA) and salicylic acid (SA) onto chitosan (CS) using free radical grafting initiated by hydrogen peroxide/Vitamin C (H 2 O 2 /Vc) redox system. We characterized the structural properties of the GA (CS-GA) and SA (CS-SA) derivatives using UV-vis absorption, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), nuclear magnetic resonance (NMR), and thermal stability analysis. We proved that these phenolic acids were successfully grafted onto the molecular skeleton of CS. We investigated the antioxidant and antibacterial properties of CS-GA and CS-SA and found that they had significantly higher antioxidant and antibacterial properties than native CS. Furthermore, the antioxidant ability increased with the increase in grafting ratios. Finally, in vivo tests showed that CS-GA could maintain the firmness and the content of soluble solids and titratable acids in Saimaiti apricots at cool storage. The storage period was prolonged by inhibiting the respiratory intensity of apricots. Our results suggest that CS-GA can be potentially used as an edible coating material to preserve apricots.

“…The development of biodegradable packaging films is extremely important, given the increasing environmental pollution caused by plastics (Sedayu et al, 2019). The main biopolymers of biodegradable films include polysaccharides, proteins and lipids (Lian et al, 2022;Fernandes et al, 2020), among which polysaccharides have been recognized for their diversity of sources, low cost, and simple process for film formation (Mostafavi, 2019). Agar (AG), a polysaccharide extracted from marine red algae, has strong gelation properties, and can form a gel at concentrations as low as 0.004%.…”

The study aimed to improve polysaccharide-based packaging to extend the shelf life of fresh produce; a composite film with antimicrobial function was developed and tested. The packaging film is a blend of agar, a film-forming substrate; carrageenan, as a reinforcing agent; glycerol, as a plasticizer; and Nisin, an antimicrobial agent. The film was evaluated for its antibacterial, mechanical, and barrier properties at different humidity levels, using fresh-cut watermelon as the test food material. The film effectively inhibited the growth of Staphylococcus aureus and Listeria monocytogenes. Under relative humidity of 20%, 50%, and 90%, the tensile strength of the antibacterial film containing 0.28% Nisin was 23.08 ± 0.65, 16.09 ± 1.73, and 6.52 ± 0.56 MPa, respectively, and the film also had excellent barrier and heat-sealing properties. The packaging test using fresh-cut watermelon sealed in the antibacterial film containing 0.28% Nisin, under controlled atmosphere storage at either 4 °C or 20 °C, effectively inhibited microbial colonization in the melon and slowed the deterioration of the fruit, as indicated by measures of hardness, weight loss, and soluble solids. This method can extend the shelf life of fresh-cut fruit and provide a reference for further research on polysaccharide-based protective film for fresh produce.

“…Active packaging is a new packaging method that added antibacterial agent, antioxidant, deoxidizer and ethylene absorbent to the film matrix. Its purpose is to prolong the shelf life of food and maintain or improve the characteristics of packaged food (Azadbakht et al, 2018;Lian et al, 2022). Plant antibacterial agents are used to improve the antibacterial activity of films because of their safety and strong antibacterial activity.…”

In order to explore the effects of thymol on the antimicrobial activity, structure, physical properties and fresh-keeping application of starch/PBAT composite films, different contents of thymol (0, 1%, 3% and 5%) were used to prepare antimicrobial composite films by extrusion blow molding. The results indicated that tourier transform infrared spectroscopy showed there was intermolecular hydrogen bonding force among starch/PBAT and thymol. The inhibition effect on Botrytis cinerea and the preservation effect of cherry tomato of the composite film were significantly improved, the hardness and nutritional characteristics of cherry tomato were maintained, and the fruit decay rate was reduced. The addition of thymol increased the water vapor permeability of the starch based composite films, but reduced the interaction between the composite film and water. Although thymol reduced the mechanical properties of the composite film, high concentration of thymol further improved the mechanical properties. In conclusion, the high concentration of thymol improved the comprehensive properties of starch composite film, and proved the application prospect of the film as active food packaging material.
