Summary: Modified Atmosphere Packaging (MAP) is a dynamic system that modifies the atmosphere inside the package by the natural interplay between respiration of the product and permeability of the packaging film. Scientists have made tremendous efforts in developing equilibrium MAP solutions for fresh produce, and its commercial adoption has expanded to fresh-cut produce. This review critically summarizes the scientific progress in the last two decades in implementing MAP and understanding moisture condensation dynamics in the horticultural supply chain.

Summary: This study used selected-ion flow-tube mass spectrometry (SIFT-MS) to monitor the quality of volatile organic compounds (VOCs) and identify spoilage indicators for fresh pork stored under different packaging atmospheres at 4 degrees C. Different compounds were identified as markers for specific storage conditions. SIFT-MS showed promise in improving analytical efficiency and ensuring reliability in monitoring VOC profiles in various storage scenarios.

Summary: The demand for fresh-cut products, including eggplants, has increased. Combination treatments involving storage temperature, ascorbic acid concentration, and modified atmosphere packaging have been studied to inhibit browning and extend shelf life. A concentration of 2 g/L ascorbic acid combined with MAP-2 was found to effectively inhibit browning in fresh-cut eggplants over a period of four days.

Summary: This study investigated the effect of different treatments (edible coating, modified atmosphere packaging, and a combination of both) on the quality of fresh-cut pineapples during storage at 4 degrees C. The results showed that the combination treatment (edible coating + modified atmosphere packaging) was the most effective in maintaining quality and extending shelf life. This treatment inhibited water loss, respiratory rate and enzyme activity, and improved appearance, acid content, and antioxidant capacity of the pineapples.

Summary: This study investigated the effects of lemon and lemongrass essential oils (EOs) on Botrytis cinerea using enzymatic and proteomic analyses. Both EOs showed scavenging activity and increased levels of malondialdehyde and superoxide dismutase in B. cinerea mycelia. Lemon EO contained d-limonene as a major constituent (71%), while lemongrass EO contained α-citral (50.1%). Proteomics analysis identified 42 proteins, including 13 unique proteins found only in lemon and lemongrass EO-treated B. cinerea.

Summary: The application of vacuum ultraviolet (VUV) photolysis modular reactor for fruit storage was investigated in this study. The first experiment compared the effectiveness of VUV photolysis reactor with potassium permanganate (KMnO4) on ethylene removal in mixed-fruit storage, while the second study evaluated the impact of direct VUV radiation on apple quality attributes. Results showed that VUV modular reactor significantly reduced ethylene production in mixed-fruit storage compared to potassium permanganate, but direct exposure to VUV radiation damaged the skin of apples. This study demonstrated the potential of VUV photolysis as an innovative technique for ethylene removal in storage facilities.

Summary: Postharvest diseases are a major concern for table grapes, causing significant economic losses worldwide. Traditional methods for disease detection have limitations in accurately identifying asymptomatic diseases, while proteomics offers instantaneous results for early detection. This review provides an overview of postharvest disease pathogens and symptoms in table grapes, and discusses the potential of biochemical assays and proteomics for early disease management strategies. Continued development of conventional tools and integration with novel approaches is emphasized for improved early disease diagnosis.

Summary: This paper presents an analytical expression for the effectiveness factor of photocatalytic reactors accounting for external mass transfer limitations, using Robin boundary conditions and the Sherwood number as a parameter for these limitations. The study identifies regions of free diffusion, diffusion limitations, and external mass transfer limitations based on the Thiele modulus and Sherwood number. At low Sherwood number values, external mass transfer limitations surpass internal diffusion and reaction rate limitations. The cutoff value for the Sherwood number below which external mass transfer limitations cannot be ignored is 0.55. The model evaluation shows convergence with literature models under Dirichlet boundary conditions and considers a broader range of limitations associated with immobilized photocatalytic films.
