TI  - Effects of Various Polymeric Films on the Pericarp Microstructure and Storability 
      of Longan (cv. Shixia) Fruit Treated with Propyl Disulfide Essential Oil from the 
      Neem (Azadirachta indica) Plant.

AB  - Plant extracts represent a rich repository of metabolites with antioxidant and 
      antimicrobial properties. Neem (Azadirachta indica) is a medicinal plant 
      considered the tree of the 21st century. In this study, we investigated the 
      antioxidant and antimicrobial effects of propyl disulfide (PD), a major volatile 
      compound in neem seed, against the pericarp browning (BI), microbial decay 
      incidence (DI), and water loss of longan fruit. Fresh longan cv. Shixia samples 
      were packaged in oriented polypropylene (OPP) and polyethene (PE) packages of 
      different thicknesses (20, 40, and 60 microm). Sterile gauze was fixed inside the 
      packages and 500 uL of PD was placed on them to avoid the direct contact of PD 
      with fruit samples. Packages were sealed immediately to minimize vaporization and 
      stored at 12 +/- 1  degrees C for 18 days. Fruit samples packaged in open net packages 
      served as controls. The results showed that fruit treated with PD in OPP and PE 
      packages significantly prevented losses of water, DI, and BI compared to control 
      treatment. PD also maintained the color, TSS values, TA values, pH values, high 
      peel firmness, high TPC content, and high TFC content, and reduced the activity 
      levels of PPO and POD. Scanning electron microscope (SEM) analysis indicated that 
      the exocarp, mesocarp, and endocarp of longan peel were smooth, uniform, and 
      compact with no free space compared to control, where crakes, a damaged and loose 
      structure, and a lot of fungal mycelia were found. The shortest shelf life of 9 
      days was observed in control as compared to 18 days in OPP-20 and OPP-40; 15 days 
      in OPP-60, PE-20, and PE-40; and 12 days in PE-60 packaging films. Therefore, PD 
      as a natural antioxidant and antimicrobial agent, in combination with OPP-20 and 
      OPP-40 polymeric films, could successfully be applied commercially to extend the 
      postharvest shelf life of longan.
