Edible film based on corn zein containing dill extract and essential oil/β‐cyclodextrin inclusion complex: Shelf life enhancement of common carp fillet

Abstract

Due to its high nutritional value, abundance, growth rate, and pleasant taste, the common carp (Cyprinus carpio) is known as one of the main edible freshwater fish species. High pH value, polyunsaturated fatty acids, and nonprotein nitrogen (NPN) compounds followed by fast microbial growth, oxidation, and autolytic reactions have decreased the shelf life of this desirable product (Moosavi-Nasab et al., 2016). Active edible films and coatings with natural origin are the new approach for the shelf life enhancement of foods that have

Comparison of green and synthetic silver nanoparticles in zein‐based edible films: Shelf‐life study of cold‐stored turkey breasts

“…They concluded that this effect can be related to the antibacterial effects of the designated coating in the studied chicken meat during storage time (Barkhordari & Bazargani‐Gilani, 2021 ). Zolfaghari et al ( 2023 ) observed the significant ( p ≤ .05) antibacterial activity of the zein edible film containing encapsulated dill essential oil and extract in the refrigerated common carp fillets. They reported that the designated zein edible film could significantly ( p ≤ .05) control the pH changes of the studied samples compared to the unwrapped fillets during 12 days of the storage period.…”

“…In other words, potent antimicrobial effects of Ag nanoparticles caused the low bacterial population, followed by the low TVB‐N value in the cold‐stored turkey breast meat. Zolfaghari et al ( 2023 ) designed an edible film based on corn zein containing encapsulated dill essential oil for the shelf‐life enhancement of the common carp fillets under refrigeration conditions. They concluded that the produced activated zein film had significant ( p ≤ .05) antibacterial activity and therefore could prevent the increase in the TVB‐N value in the common carp fillets during storage period.…”

“…The films were produced by the casting method so that the required amount of the prepared solutions was poured into the sterile Petri plates; then, the mold was gently shaken to distribute the solution evenly. Finally, to desiccate the film, the molds were kept on a flat surface at room temperature for 24 h. Upon complete drying, the films were slowly removed from the mold (Zolfaghari et al, 2023 ).…”

“…Biopolymers are the main basis for the production of the natural packaging. Among different biopolymers, Zein is known as an ideal substance given its properties, such as excellent plasticity, biodegradability, and harmlessness (Zolfaghari et al, 2023 ). Zein is a hydrophobic protein in corn endosperm and a byproduct of corn milling.…”
