The aims of the current study were to encapsulate Mentha longifolia L. essential oil (MEO; 0.5, 1, and 2%) into carboxymethyl cellulose-gelatin (CMC-GE) nanofibers via electrospinning and to evaluate the effects of fabricated nanofibrous films on improving the shelf-life of peeled freshwater prawns during refrigerated storage for 14 days. CMC-GE-MEO 0.5%, CMC-GE-MEO 1%, and CMC-GE-MEO 2% nanofibrous films showed significantly lower force (21.74-25.33 N), tensile strength (6.52-8.56 MPa), water vapor permeability (7.25-9.34 x 10(-4) g mm/m(2) h Pa), and swelling index (20.14-27.45%) compared to the neat CMC-GE (p < 0.05). The elongation at break significantly increased when MEO was incorporated into the CMC-GE (p < 0.05). The neat CMC-GE had the highest blue-yellow index (b = 1.02 +/- 0.01) and the lowest green-red index (a = 0.12 +/- 0.01) and lightness (L = 95.92 +/- 0.07). CMC-GE-MEO 1% and CMC-GE-MEO 2% nanofibrous films successfully improved the microbial population and chemical property of peeled prawns for 12 and 14 days, respectively. Prawns packaged with CMC-GE-MEO 2% nanofibrous film had significantly the highest sensory scores in terms of odor, color, texture, taste, and total acceptance throughout the study period (p < 0.05).
