“…Mag is a common medicine used for oral or topical treatment of various diseases, and its safety in humans is high (Sun et al, 2015b;Lin et al, 2021). In addition, CMCS, CMC, PT, SA, and Gl used in the Mag@CMCS@CPSG films are natural products that are often used in food processing (Riahi et al, 2022;Li et al, 2023). This indicates that the Mag@CMCS@CPSG film is a non-toxic or low-toxic agent and an ideal material for the green control of plant diseases.…”

To find a precise, efficient, and safe method to control rice sheath blight disease (caused by Rhizoctonia solani), this study used the natural product magnolol as the fungicide. Based on the characteristics of cell wall-degrading enzymes (CWDEs) released by R. solani during the early stages of infection, a Mag@CMCS@CPSG (magnolol@carboxymethyl chitosan@carboxymethyl cellulose, pectin, sodium alginate, and glycerol) film was constructed to control the release of magnolol in response to CWDEs. The Mag@CMCS@CPSG film increased magnolol toxicity against R. solani, decreased EC50 from 7.33 μg/mL to 4.37 μg/mL, and effectively blocked the invasion of mycelia. Under the stimulation of CWDEs released during R. solani infection, the cumulative release of magnolol by the Mag@CMCS@CPSG film reached 75.62% after 96 h, and the disease index of rice treated with Mag@CMCS@CPSG film significantly decreased. The maximum field control effect of Mag@CMCS@CPSG film on rice sheath blight disease was 72.47%, which was not significantly different from that of the commercial preparation jinggangmycin; however, the holding period was better. The Mag@CMCS@CPSG film reduced the loss of rice yield and quality caused by infection with R. solani and did not cause phytotoxicity or residue. In conclusion, the Mag@CMCS@CPSG film can achieve accurate and green control of rice sheath blight.

The inevitable drawbacks of petrochemical polymer‐based packaging (e.g., extreme loss of fossil resources, excessive products’ carbon footprint, and inordinate environmental pollution resulting from the accumulation of disposed nonbiodegradable plastic‐based packages) have urged scientists to develop novel packaging materials from nature‐inspired biopolymers. Due to their biodegradability, non‐toxicity, film‐forming ability, and barrier properties versus gasses/aroma, polysaccharides have been increasingly valued in developing food packaging materials at the lab or industrial scale. Nonetheless, these valuable biopolymers also suffer from some inherent deficiencies, that is, low resistance to water and poor mechanical attributes. Hitherto, tackling such bottlenecks via the modification of biopolymers through chemical/physical approaches and applying a combination of several biopolymers has been the main focus of numerous recent studies. In this context, the present article, for the first time, provides a comprehensive update on the most recent utilization of common polysaccharides (e.g., starch, chitosan, xanthan gum, gum Arabic, alginate, gellan, pectin, and carrageenan) for food packaging applications.

This study investigates the incorporation of anthocyanin-rich extracts from Mountain Pepper Berry (MPB) and Queen Garnet Plum (QGP) into pectin-based films to develop pH-sensitive indicators. Using glycerol as an extraction solvent, significant differences in anthocyanin composition were identified: MPB extracts contained a diverse range of anthocyanin species, with a total content of 267.13 ± 5.21 mg L⁻¹, compared to the predominantly cyanidin-based QGP extracts, with 222.14 ± 1.61 mg L⁻¹. Differences in anthocyanin structures were elucidated using UPLC-Q-ToF-MS/MS analysis. FTIR and UV-Vis spectroscopy were used to assess the compatibility of the extracts with pectin and the homogeneity of anthocyanins within the film structure. Mechanical testing revealed that MPB films exhibited superior tensile strength (8.53 ± 0.51 MPa), stiffness (2274 ± 158.64 gmm− 1), and energy to failure (141.7 ± 16.23 J m− 3) compared to QGP films, which had lower tensile strength (7.74 ± 0.32 MPa), stiffness (1947 ± 125.82 gmm− 1), and energy to failure (115 ± 18.81 J m− 3). Both film types displayed similar moisture content (MPB: 48.89%, QGP: 48.13%) and water vapour permeability, indicating comparable barrier properties. When exposed to volatile ammonia, QGP films showed a more pronounced colour change, attributed to their anthocyanin profile, with a notable shift from red to brown. This research highlights the potential of glycerol-extracted anthocyanins from Australian native fruits as functional additives in pectin films, offering promising applications for intelligent packaging with enhanced mechanical performance and responsive colour-changing properties.
