Electrospun carboxymethyl cellulose-gelatin nanofibrous films encapsulated with Mentha longifolia L. essential oil for active packaging of peeled giant freshwater prawn

Abstract 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 × 10‾4 g mm/m2 h Pa), and swelling index (20.14–27.45%) compared to the neat CMC-GE (p
