    (Elsevier, 2023) Koirala, Pankaj; Nirmal, Nilesh Prakash; Woraprayote, Weerapong; Visessanguan, Wonnop; Bhandari, Yash; Karim, Nurul Ulfah; Saricaoglu, Furkan Turker
    Seafood is a high-value market product well known for its nutrition and easily digestible protein. However, they are highly vulnerable to postharvest storage such as microbial deterioration and oxidation process (protein and lipid oxidation). Hence, various strategies have been employed to preserve the quality of seafood products, including chemical additives, natural preservatives, packaging, and coatings. This review discusses the recent advancement of nanotechnology in edible films and coatings for the shelf-life extension of seafood products. Firstly, quality changes in seafood products and biopolymers used in edible films and coatings have been summarized. A brief discussion has been provided on the various nanotechnology approaches to formulate nano -engineered edible films and coatings. Additionally, the quality and shelf-life extension of seafood products in terms of antioxidant and antimicrobial control using nano-engineered edible films and coatings have been dis-cussed. Finally, safety, regulatory issues, and future prospectus on nano-engineered edible films and coatings are reported.

    Natural colorant incorporated biopolymers-based pH-sensing films for indicating the food product quality and safety
    (Elsevier Ltd, 2024) Parlak, Mahmut Ekrem; Irmak Sahin, Oya; Dundar, Ayşe Neslihan; Sarıcaoğlu, Furkan Turker; Smaoui, Slim; Gökşen, Gülden; Koirala, Pankaj
    The current synthetic plastic-based packaging creates environmental hazards that impact climate change. Hence, the topic of the current research in food packaging is biodegradable packaging and its development. In addition, new smart packaging solutions are being developed to monitor the quality of packaged foods, with dual functions as food preservation and quality indicators. In the creation of intelligent and active food packaging, many natural colorants have been employed effectively as pH indicators and active substances, respectively. This review provides an overview of biodegradable polymers and natural colorants that are being extensively studied for pH-indicating packaging. A comprehensive discussion has been provided on the current status of the development of intelligent packaging systems for food, different incorporation techniques, and technical challenges in the development of such green packaging. Finally, the food industry and environmental protection might be revolutionized by pH-sensing biodegradable packaging enabling real-time detection of food product quality and safety. © 2023 Elsevier Ltd
