Nature Nano-Barrier: HPMC/MD-Based <i>Lactobacillus plantarum</i> Pickering Emulsion to Extend Cherry Tomato Shelf Life
To improve the postharvest preservation of cherry tomatoes and combat pathogenic, both bacterial and fungal contamination (particularly <i>Alternaria alternata</i>), a novel biodegradable coating was developed based on a water-in-water (W/W) Pickering emulsion system. The emulsion was st...

| description | To improve the postharvest preservation of cherry tomatoes and combat pathogenic, both bacterial and fungal contamination (particularly <i>Alternaria alternata</i>), a novel biodegradable coating was developed based on a water-in-water (W/W) Pickering emulsion system. The emulsion was stabilized by <i>L. plantarum</i> (<i>Lactobacillus plantarum</i>), with maltodextrin (MD) as the dispersed phase and hydroxypropyl methylcellulose (HPMC) as the continuous phase. Characterization of emulsions at varying concentrations revealed that the optimized W/W-PL^8 film exhibited superior stability, smooth morphology, and low water vapor permeability (WVP = 220.437 g/(m<sup>2</sup>·24 h)), making it a promising candidate for fruit and vegetable preservation. Furthermore, the coating demonstrated strong antioxidant activity, with scavenging rates of 58.99% (ABTS) and 94.23% (DPPH), along with potent antimicrobial effects, showing inhibition rates of 12.8% against <i>Escherichia coli</i> and 23.7% against <i>Staphylococcus aureus</i>. Applied to cherry tomatoes, the W/W-PL^8 coating significantly reduced respiration rates, minimized decay incidence, and maintained nutritional quality during storage. Remarkably, the coating successfully controlled <i>Alternaria alternata</i> contamination, enhancing the storage duration of cherry tomatoes. These findings highlight the potential of W/W-PL^8 as an eco-friendly and functional packaging material for fresh produce preservation. |
