Development of a nanofiber sheet containing methyl jasmonate produced by electrospinning technique for delaying senescence in perishable crops was studied. Nanofibers contain highly porous mesh with their large surface-to-volume ratio which has much advantage for improving performance for many applications. This research aims to develop the nanofiber sheet containing methy jasmonate. The first study was to produce the proper nanofiber sheet by varying the combination of three polymers as chitosan, cellulose and gelatin for nanofiber sheet. Nanofiber sheets of various proportions of chitosan, cellulose and gelatin as 40:10:50, 40:20:40, 40:30:30 (chitosan: cellulose:gelatin) were produced by using an electrospinning machine. The distance of polymer shooting, flow rate of polymer injection and potential difference of electricity supply was varied to find the suitable condition for producing the carried nanofiber sheet. The result revealed that the 40:30:30 (chitosan:cellulose:gelatin) with 10 cm of polymer shooting distance, 11.67 μL min-1of polymer flow rate and 23 kV of potential difference was the best condition for producing the nanofiber sheet. Afterward, this condition was chosen to the further experiment. Various concentrations of methyl jasmonate were added into the polymer solution prior to shooting the nanofiber by electrospinning machine. The results suggested that 5 mM methyl jasmonate electrospun nanofibers revealed the proper morphology with the smallest size of fiber diameter without any droplet of bead, easy to crack. This treatment could potentially be used for delaying senescence of postharvest fruit and vegetable. © 2022 International Society for Horticultural Science. All rights reserved.
