A Microporous Breathable Packaging System for the Postharvest Preservation of Figs (Ficus carica L.) in E-Commerce Logistics

concentration within the package, as the gas exchange rate through the packaging film is insufficient to compensate for the high respiration rate of figs. To explore the effectiveness of packaging in indirectly reducing ethylene accumulation during E-commerce logistics, this study optimized parameters of laser microporous-modified atmosphere packaging (LMMAP) and investigated the effects of LMMAP on the shelf life of figs. Results showed that LMMAP (20 micropores, 300-314 μm in diameter; 30 micropores, 260-270 μm in diameter) effectively regulated the rate of gas exchange across the packaging film under high temperature and vibration stress during transportation. Four days after storage, LMMAP significantly reduced the respiration rate and decay incidence, delayed ethylene release, and maintained the firmness, color and sensory qualities in figs under the same stress conditions. Moreover, LMMAP significantly inhibited the decrease in total soluble solids and titratable acidity content in figs. It also maintains a high antioxidant capacity and reduces the damage to the cell membrane caused by reactive oxygen species. In summary, LMMAP maintains the quality and extends the shelf life of figs during E-commerce logistics.
