“…Conventionally, food packaging materials (FPMs) are developed using plastics, which account for a sizable amount of petroleum oil consumption. It has been forecasted that by the year 2050, 20% of petroleum oil will be used for the manufacturing of plastics for different applications [ 2 ]. The use of plastics results in the overall carbon emissions of the earth, thereby negatively affecting nature.…”

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.

“…For these types of products, the improvement of the environmental performance of the product can be achieved through the reduction of the packaging impact rather than interventions to improve the efficiency of the beverage production processes [ 21 ]. The use of biobased food packaging materials could meet the objectives required by the U.S Food and Drug Administration (FDA) and the European Union in terms of sustainability [ 22 , 23 ].…”

The aim of the present study is to assess the use of polylactic acid (PLA) bottles as an alternative to polyethylene terephthalate (PET) ones for high-pressure processing (HPP) of apple juice. The treatment of PLA bottles at 600 MPa for 3 min did not cause alterations in the packaging shape and content, confirming the suitability of PLA bottles to withstand HPP conditions as well as PET bottles. Quantification of total mesophilic bacterial and fungal load suggested HPP treatment can be effectively applied as an alternative to pasteurization for apple juice packed in PLA bottles since it guarantees microbial stability during at least 28 days of refrigerated storage. The headspace gas level did not change significantly during 28 days of refrigerated storage, irrespective of the bottle material. Color parameters (L*, a*, and b*) of the HPP-treated juice were similar to those of the fresh juice. Irrespective of the packaging type, the total color variation significantly changed during storage, showing an exponential increase in the first 14 days, followed by a steady state until the end of observations. Overall, PLA bottles proved to offer comparable performances to PET both in terms of mechanical resistance and quality maintenance.

“…Many bioplastics from biopolymers such as starch, cellulose, and proteins, synthetized plastics from biomass (PLA) or produced by microorganisms (PHAs and PHBs) have been extensively studied as alternative materials for food packaging [ 5 , 6 , 7 , 8 ]. Among these, chitosan has been widely used for packaging applications because of its biodegradability, non-toxicity, film-forming properties, chemical stability, and intrinsic antimicrobial and antioxidant properties [ 9 ]. Numerous studies in the applications of engineered chitosan-based films in food packaging, including composite films with other biopolymers and active compounds, have been reported and revised [ 9 , 10 , 11 , 12 ].…”

“…In this respect, chitosan is a widely studied biodegradable polymer derived from chitin that can be obtained from fishing industry residues such as crustaceous exoskeletons, which annually account for over 60,000 tons of waste [ 35 ]. Besides, it presents promising characteristics for food packaging applications because of its antioxidant and antimicrobial activity, biodegradability, non-toxicity, biocompatibility, film-forming capacity, and chemical stability [ 9 ].…”

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

et al. 2021

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.
