Special Issue Information

Dear Colleagues,

The advancement of environmentally sustainable coatings to prolong the shelf-life of food products has become essential. With consumers showing a growing preference for healthier and more natural food options, there is an increasing focus among researchers in the food industry on employing eco-friendly technologies to extend the shelf-life of foods. In this regard, paper-based packaging materials have emerged as viable solutions, simultaneously aiding in the preservation of food products. Unlike traditional plastic coatings, which present considerable environmental challenges owing to their non-biodegradable nature, eco-friendly paper packaging coatings prioritize the utilization of renewable resources and aim to minimize adverse environmental impacts across their lifecycle.

This Special Issue aims to delve into the most recent advancements and uses of eco-friendly paper packaging coatings in the context of sustainability and food preservation. It seeks to showcase research that addresses key challenges and opportunities in this emerging field, with a particular emphasis on innovative coating materials, coating techniques, and their effectiveness in maintaining food quality and safety. Furthermore, the functionalization of these novel packages to serve as carriers for bioactive compounds will also be discussed.

Researchers are invited to contribute original research articles, reviews, and case studies that shed light on various aspects of eco-friendly paper packaging coatings. Topics of interest include, but are not limited to, the following:

  • Novel materials
  • Coatings creation and design
  • Functional packaging
  • Bioactive incorporation
  • Packaging properties

Over the last decades, a significant rise in fruit consumption has been noticed as they contain numerous nutritional components, which has led to the rise in fruit production globally. However, fruits are highly liable to spoilage in nature and remain vulnerable to losses during the storage and preservation stages. Therefore, it is crucial to enhance the storage life and safeness of fruits for the consumers. To keep up the grade and prolong storage duration, various techniques are employed in the food sector. Among these, biopolymer coatings have gained widespread acceptance due to their improved characteristics and ideal substitution for synthetic polymer coatings. As there is concern regarding the safety of the consumers and sustainability, edible coatings have become a selective substitution for nurturing fruit quality and preventing decay. The application of polysaccharide-based edible coatings offers a versatile solution to prevent the passage of moisture, gases, and pathogens, which are considered major threats to fruit deterioration. Different polysaccharide substances such as chitin, pectin, carrageenan, cellulose, starch, etc., are extensively used for preparing edible coatings for a wide array of fruits. The implementation of coatings provides better preservation of the fruits such as mango, strawberry, pineapple, apple, etc. Furthermore, the inclusion of functional ingredients, including polyphenols, natural antioxidants, antimicrobials, and bio-nanomaterials, into the edible coating solution matrix adds to the nutritional, functional, and sensory attributes of the fruits. The blending of essential oil and active agents in polysaccharide-based coatings prevents the growth of food-borne pathogens and enhances the storage life of the pineapple, also improving the preservation of strawberries and mangoes. This paper aims to provide collective data regarding the utilization of polysaccharide-based edible coatings concerning their characteristics and advancements for fruit preservation. Full article
