This paper explores the potential of alginate-based food packaging as an environmentally friendly method for food-related issues. Alginate, a naturally occurring polysaccharide extracted from seaweed, has considerable potential as a sustainable packaging material due to its multifaceted properties. These properties enable alginate to encapsulate and preserve a wide range of food products effectively. Alginate food packaging has demonstrated its ability to prolong the shelf life of various food products, including fresh fruits, vegetables, meats, and baked goods. It is beneficial to maintain their moisture content and maintain oxygen levels. Furthermore, it is an effective barrier against microbial growth, while preserving the desired flavor and aroma profiles of the packaged items. Antimicrobial food packaging systems are specifically designed to inhibit microbial growth on surfaces, thus enhancing overall stability and preserving quality during storage periods. However, additional research is necessary to improve performance across various applications within the food industry. Alginate-based edible coatings have attracted significant attention due to their ability to enhance both sensory attributes, such as appearance, and mechanical properties across diverse categories including fruits, vegetables, meat, poultry, seafood, and cheese. These edible films mitigate drying effects on contents by regulating the respiration rate, ensuring optimal conditions for extended freshness and shelf life.</p>","PeriodicalId":101198,"journal":{"name":"Sustainable Food Technology","volume":" 5","pages":" 1246-1265"},"PeriodicalIF":0.0,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/fb/d3fb00216k?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142246628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, there has been a growing interest in the use of biopolymers in food packaging and other applications due to their renewable origin and biodegradable properties, which have a positive environmental benefit. Hemicelluloses are biodegradable heteropolymers, which are associated with lignocellulose cell walls of vegetative and storage tissues of annual and perennial plants. They represent an immense renewable resource of biopolymers. Hemicelluloses are the second most abundant component of lignocellulosic biomass, and they are comparatively underutilized in industrial applications, even though it is a main by-product or residue in the lignocellulosic biomass processing. Therefore, it is important to include hemicellulose valorisation through the biorefinery concept to promote a Sustainable Bioeconomy (SBE), Circular Bioeconomy (CBE), and Circular Economy (CE). Extraction procedures on different plants have enabled the isolation of a diversity of hemicellulose structures with different yields and purities. However, compared to other biopolymers, their commercial uses have been underscored by their low yields, hydrophilicity, and low mechanical strength. While the applications of pure hemicelluloses are limited in the food industry, the use of hemicellulose composites as edible films, coatings, preservatives, fillers, and emulsifiers, is more promising.
