11/9/2023 0 Comments Gse usesEven though plenty of research has already been published on GSE-added packaging films and coatings, there is no comprehensive review on this topic. GSE-added packaging was highly effective in preserving fresh and processed food. Some of the reported functional films were used for real-time packaging of bread, fruits, or fish, and in most cases, it has been reported that the presence of GSE significantly improves the shelf life of packed food. GSE has been added to the varieties type of polymer matrices, such as alginate, agar, polylactic acid, carrageenan, gelatin, etc., to manufacture functional packaging film or coating. Due to its strong functional properties, recently, there is growing interest in GSE-added film and coatings. Nevertheless, it has also been reported that the pure ethanolic extract of GSE showed potent antimicrobial activity toward foodborne pathogens. The strong antimicrobial activity of GSE has become a topic of debate, since it has been shown that commercial GSE includes some chemical csompounds, such as benzalkonium and benzethonium compounds, which shows antimicrobial activity. The strong functional properties of GSE have recently been used in combination with xylitol as a nasal spray to cure COVID-19 patients. GSE is citrus-derived functional material containing different bioactive components like flavonoids, polyphenols, organic acid, etc., which are believed to be responsible for the strong antimicrobial and antioxidant activity. GSE has been used in many applications such as wound healing, antioxidant, antibacterial, antidiabetic, preservative, food packaging, etc.īiological properties and food applications of GSE. The application of GSE in health and food is represented in Figure 1, which clearly illustrates the potential of GSE. Among the various types of natural functional materials, grapefruit seed extract (GSE) is well known and broadly used in the food and pharmaceutical sector. To this end, essential oils and plant extracts have increased significantly recently due to their strong antibacterial and antioxidant activity and safety. Since chemical preservatives are toxic, natural, or naturally derived, functional compounds are gaining popularity among consumers. Even in the food packaging sector, many chemical compounds, like benzoic acid, propionic acid, sorbic acid, etc., are frequently used. Commercially, countless chemical compounds are used as food preservatives. In functional packaging, the antimicrobial and antioxidant compounds are infused into the packaging matrix. Recently, functional food packaging is emerging as a hot topic to strengthen the safety and security of food. Food packaging films or coatings can improve the food shelf life and ensure food safety by limiting the growth of foodborne microbes. Foodborne pathogens and food spoilage are generally controlled by employing food preservatives during food packaging. In this regard, food packaging or using food preservatives directly in the food or as a packaging matrix are traditionally used. Thus, reducing the risk associated with foodborne pathogens is very important. Interestingly, pathogen proliferation sometimes occurs without changing the foods’ physical characteristics (color, flavor, and odor). Food poisoning is often caused due to the growth of unwanted foodborne pathogenic microbes during food storage. Recently, food safety and security have been seriously recognized due to the growing problem of foodborne diseases worldwide. Lastly, the opportunities, challenges, and perspectives in the GSE-added packaging film/coating are also debated. This review also provides the food preservation application of GSE-incorporated film and coating. Various physical and functional properties of GSE-added film were also discussed. This review discusses GSE, its extraction methods, and their use in manufacturing food packaging film/coatings. A lot of recent work reports the use of GSE in food packaging applications to ensure food quality and safety therefore, this work intended to provide an up-to-date review of GSE-based packaging. GSE is a very commonly used antimicrobial in food lately, it has also been found very effective as a coating material or in edible packaging films. Several bioactive compounds have originated from natural sources, and among them, grapefruit seed extract (GSE) is widely accepted and generally safe to use in food. Recently, consumers have been increasingly inclined towards natural antimicrobials and antioxidants in food processing and packaging.
