Fabrication and characterization of gelatin/carboxymethyl chitosan composite film incorporated with carvacrol and its preservation efficacy in Chinese mitten crab (Eriocheir sinensis)

The demand for active food packaging to enhance the shelf-life of food products is increasing globally. Hence, composite films were fabricated with gelatin (GL) and carboxymethyl chitosan (CC) at different carvacrol (CA) proportions (0, 1, 2, and 3 %). The physical and chemical properties, morpholog...

Description
Summary:The demand for active food packaging to enhance the shelf-life of food products is increasing globally. Hence, composite films were fabricated with gelatin (GL) and carboxymethyl chitosan (CC) at different carvacrol (CA) proportions (0, 1, 2, and 3 %). The physical and chemical properties, morphology, molecular characteristics, and bioactivities were investigated. CA markedly improved the thickness, tensile strength, elongation-at-break, and opacity of the films, ranging from 0.12 to 0.17 mm, 26.92–47.46 MPa, 29.15–32.67%, and 1.73–3.88 mm in GL/CC/CA-0 and 3%, respectively (p
