“…The quality of packaging films decides the shelf life of the encapsulated food [ 7 , 8 ]. A variety of biodegradable polymers are used in the food packaging industry, which include polylactic acid (PLA), polyimide (PI) [ 9 , 10 ], and natural polymers such as gelatin [ 11 , 12 ] and fruit extracts [ 13 , 14 , 15 ]. Most of these polymers have good film formability but possess poor barrier characteristics against the diffusion of moisture and oxygen.…”

Sustainable and Eco-Friendly Packaging Films Based on Poly (Vinyl Alcohol) and Glass Flakes

The majority of food packaging materials are petroleum-based polymers, which are neither easily recyclable nor ecologically friendly. Packaging films should preferably be transparent, light in weight, and easy to process, as well as mechanically flexible, and they should meet the criteria for food encapsulation. In this study, poly (vinyl alcohol) (PVA)-based films were developed by incorporating glass flakes into the films. The selection of PVA was based on its well-known biodegradability, whereas the selection of glass flakes was based on their natural impermeability to oxygen and moisture. The films were processed using the blade coating method and were characterized in terms of transparency, oxygen transmission rate, mechanical strength, and flexibility. We observed that the incorporation of glass flakes into the PVA matrix did not significantly change the transparency of the PVA films, and they exhibited a total transmittance of around 87% (at 550 nm). When the glass flakes were added to the PVA, a significant reduction in moisture permeation was observed. This reduction was also supported and proven by Bhardwaj’s permeability model. In addition, even after the addition of glass flakes to the PVA, the films remained flexible and showed no degradation in terms of the water vapor transmission rate (WVTR), even after bending cycles of 23,000. The PVA film with glass flakes had decent tensile characteristics, i.e., around >50 MPa. Increasing the concentration of glass flakes also increased the hardness of the films. Finally, a piece of bread was packaged in a well-characterized composite film. We observed that the bread packaged in the PVA film with glass flakes did not show any degradation at all, even after 10 days, whereas the bread piece packaged in a commercial polyethylene bag degraded completely. Based on these results, the developed packaging films are the perfect solution to replace commercial non-biodegradable films.

“…To this end, essential oils and plant extracts have increased significantly recently due to their strong antibacterial and antioxidant activity and safety [ 4 , 9 , 10 , 11 , 12 ]. Among the various types of natural functional materials, grapefruit seed extract (GSE) is well known and broadly used in the food and pharmaceutical sector [ 1 , 13 ]. The application of GSE in health and food is represented in Figure 1 , which clearly illustrates the potential of GSE [ 14 ].…”

Grapefruit Seed Extract-Added Functional Films and Coating for Active Packaging Applications: A Review

et al. 2023

View full text Add to dashboard Cite

Recently, consumers have been increasingly inclined towards natural antimicrobials and antioxidants in food processing and packaging. 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. 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. 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. This review discusses GSE, its extraction methods, and their use in manufacturing food packaging film/coatings. Various physical and functional properties of GSE-added film were also discussed. This review also provides the food preservation application of GSE-incorporated film and coating. Lastly, the opportunities, challenges, and perspectives in the GSE-added packaging film/coating are also debated.

The food packaging sector is focused on developing innovative materials to enhance food safety and quality while reducing environmental impact. Accordingly, this study aimed to develop packaging based on bovine gelatin (G) blended with crude sweet orange juice pomace pectin (SOPP) at different ratios (G/SOPP = 85/15, 65/35, 50/50, w/w). The obtained crude SOPP was highly methylated and exhibited antioxidant and antibacterial properties due to the presence of galacturonic acid (<70%) and phenolic compounds (58.2 ± 0.8 mg/g SOPP). High‐performance liquid chromatography with diode array detection analysis revealed the presence of hesperidin, catechin, and naringin as major phenolic compounds in SOPP. Further, the incorporation of this latter improved gelatin‐based packaging structural homogeneity, opacity, water vapour barrier features, glass transition temperature and tensile strength. G‐SOPP (50/50) film showed efficient antibacterial activity against Escherichia coli and Bacillus subtilis and high antioxidant potential reaching values of 0.7, 48.7%, 76.7% and 68.9% for reducing power, β‐carotene bleaching inhibition, DPPH (2,2‐diphenyl‐1‐picrylhydrazyl) and ABTS+ (2,2′‐azinobis‐[3‐ethylbenzothiazoline‐6‐sulphonic acid]) radicals scavenging activities, respectively. Another interesting finding is that the combination of G and SOPP reduced the oil solubility of G‐SOPP films suggesting great physical integrity of the film over 63 days. The polyphenol content released from G‐SOPP blend film in a fatty simulant increased as SOPP content of films was increased. G‐SOPP (50/50) film, designed as a pouch, delays the photooxidation process of virgin olive oil over 63 days of storage time, without altering its organoleptic properties. Overall, these outstanding results highlighted the potential use of gelatin–pectin blend films for active packaging of oils and lipid‐based foods.
