“…The low molecular weight terpenes and terpenoids are the primary constituents responsible for the antimicrobial activity of the EOs. The composition of the EOs is analyzed mainly by chromatographic techniques such as gas chromatography, and ultra-high-performance liquid chromatography [43]. The EOs appear as colorless liquids.…”

Essential Oil-Containing Polysaccharide-Based Edible Films and Coatings for Food Security Applications

2021

The wastage of food products is a major challenge for the food industry. In this regard, the use of edible films and coatings have gained much attention due to their ability to prevent the spoilage of the food products during handling, transport, and storage. This has effectively helped in extending the shelf-life of the food products. Among the various polymers, polysaccharides have been explored to develop edible films and coatings in the last decade. Such polymeric systems have shown great promise in microbial food safety applications. The inclusion of essential oils (EOs) within the polysaccharide matrices has further improved the functional properties of the edible films and coatings. The current review will discuss the different types of polysaccharides, EOs, methods of preparing edible films and coatings, and the characterization methods for the EO-loaded polysaccharide films. The mechanism of the antimicrobial activity of the EOs has also been discussed in brief.

“…However, to meet market demands the use of industrial scale technologies adapting available equipment for synthetic materials, such as extrusion or compression molding is required [ 11 ]. In these cases, it would be necessary to protect the active agents because of their thermolability, encapsulation being a viable alternative for this purpose [ 3 ]. New technologies such as the formulation of nanoemulsions and the encapsulation of active principles could be useful for this purpose, though further studies are needed in this regard.…”

“…Because of their low cost and density plastic materials are most frequently used for packaging applications. Approximately 42% of the global plastic production is consumed by the packaging sector, being generally disposable items that contribute to the generation of large volumes of waste [ 3 ]. Even though the amount of post-consumer plastic waste sent to recycling has more than doubled in the last 15 years (32.5%), almost 25% was still sent to landfill in 2018 [ 4 ].…”

“…Synthetic chemical preservatives commonly used in antimicrobial food packaging include organic acids and their salts, sulfites, chlorides, phosphates, epoxides, hydrogen peroxide, antibiotics, and bacteriocins [ 3 ]. However, the use of plant extracts and essential oils (EOs) as additives for active food packaging have been studied and reviewed aiming to replace synthetic preservatives because of their antioxidant and antimicrobial properties and Generally Recognized as Safe (GRAS) character [ 36 , 37 ].…”

“…However, the use of plant extracts and essential oils (EOs) as additives for active food packaging have been studied and reviewed aiming to replace synthetic preservatives because of their antioxidant and antimicrobial properties and Generally Recognized as Safe (GRAS) character [ 36 , 37 ]. Agroindustrial by-products, particularly from fruit and vegetables processing, contain vitamins, minerals, antioxidants, and antimicrobial compounds for food preservation, though are often discarded or used for animal feed [ 3 ]. Thus, the use of these active compounds from agricultural by-products not only contribute to the recovery of these compounds with specific activities but also generate added value to them.…”

Bio-Packaging Material Impact on Blueberries Quality Attributes under Transport and Marketing Conditions

Blueberries are highly appreciated for their high antioxidant content but are also particularly susceptible to fungal deterioration. In this work, corn starch and chitosan, byproducts of the fishing industry, as well as active compounds obtained from citrus processing waste were used to obtain active biodegradable film packaging. Blueberries were packed in corn starch–chitosan (CS:CH) films and in active films containing lemon essential oil (LEO) or grapefruit seed extract (GSE). The effects of film packaging on the quality parameters of berries and the fungal incidence of disease during storage were studied and compared to benchmark materials. A conservation assay simulating transport and commercialization conditions was conducted. Blueberries packed in CS:CH films showed antioxidant capacity values closer to those packed in commercial PET containers (Clamshells), preserving 84.8% of the initial antioxidants content. Fruit packed in LEO films exhibited the greatest weight loss and rot incidence, and poor surface color. CS:CH and GSE films controlled the fruit respiration rate and weight loss, therefore they are materials with adequate barrier properties for blueberries conservation. Bags formulated with GSE showed adequate barrier properties to maintain fruit quality attributes without the incidence of rottenness, being an interesting option for blueberries exportation.
