“…The intense peaks at 1742 and 1643 cm −1 due to stretching vibration of methylated and non-methylated carboxylic groups, respectively, indicate the high methoxylation of pectin. The peak at 1141 cm −1 denoted the stretching vibration of C–O–C (glycosidic bond) belonging to the saccharide structure 10 , 53 . Increasing the amount of CNC in PC/CNC composite films resulted in an increased intensity and width of the O–H peak and a shift to a higher wavenumber (Fig.…”

“…Pectin properties are influenced by the degree of methyl esterification, which varies according to plant origin and processing conditions 9 . Pectin’s biodegradability, biocompatibility, gelation properties, and non-toxicity highly favor its suitability as a food packaging material 10 ; however, its moderate barrier, thermal and mechanical properties besides its high hydrophilic nature, may limit its applicability 11 . Recently, biopolymer-based active packaging systems have attracted the interest of both academia and industrial sectors for the purpose of maintaining food safety and quality.…”

Novel pectin-based films reinforced with crystalline nanocellulose (CNC) and activated with zinc oxide nanoparticles (ZnO NPs) were prepared by solvent-casting method. Film ingredients enhanced UV-blocking, thermal, and antibacterial properties of active films against well-known foodborne pathogens. Optimal active films exhibited higher mechanical, water vapor barrier properties compared to pristine pectin films. SEM confirmed the even distribution of CNC and ZnO NPs in pectin matrix and their interactions were proven using FTIR. Wrapping hard cheese samples artificially contaminated with Staphylococcus aureus and Salmonella enterica with the ternary nanocomposite film at 7 °C for 5 days significantly reduced the total population counts by at least 1.02 log CFU/g. Zn2+ migrating to wrapped cheese samples was below the specific limit (5 mg/kg), confirming their safety for food contact. Overall, ZnO/CNC/pectin nanocomposite films represent promising candidates for active food packaging as safe, eco-friendly alternatives for synthetic packaging materials.

“…Khalil [ 58 ] collected three bioactive ingredients from citrus peels; i.e., grapefruit peel methanolic extract (GFPE), grapefruit pectin (GFPec), and lemon peel extracts (LPE). First, LPE was encapsulated by maltodextrin (MD-LPE); second, active films named GFPec-GFPE/MD-LPE were prepared using MD-LPE, GFPec, and GFPE.…”

At a time when food safety awareness is increasing, attention is paid not only to food and additives but also to packaging materials. Most current food packaging is usually made of traditional petroleum-based polymeric materials, which are not biodegradable and have adverse effects on the environment and health. In this context, the development of new non-toxic and biodegradable materials for extending the best-before date of food is receiving increasing attention. In addition, additives in packaging materials may migrate outward, resulting in contact with food. For this reason, additives are also seen as a transition from synthetic additives to natural extracts. Active extracts from animals and plants having good antioxidant and antibacterial properties are also beneficial for human health. It is indisputable that active extracts are ideal substitutes for synthetic additives. Polymer packaging materials combined with active extracts not only maintain their original mechanical and optical properties and thermal stability but also endow polymers with new functions to extend the shelf life of food. This review paper provides an overview of this promising natural extract-containing polymer-based active packaging, with a focus on plant essential oils (containing phenolics, monoterpenes, terpene alcohols, terpene ketones, and aldehydes), pigments (procyanidins), vitamins (vitamin B), and peptides (nisin). In particular, this paper covers the research progress of such active extracts, in single or compound forms, combined with diverse polymers (mostly biopolymers) for food packaging applications with particular focus on the antioxidant and antibacterial properties of packaging materials.

“…It possessed gel-forming properties and good film-forming capabilities [17]. Reports indicated that pectin extracted from grapefruit peel exhibited superior thermal stability and physicochemical properties compared to commercially available citrus pectin, especially in terms of its methoxylation degree, anhydrous uronic acid, and moisture content [18]. IDF, such as cellulose, hemicellulose, lignin, and other types of IDF, were insoluble in water, and they could be prepared into nano cellulose [19] as a filler to improve the mechanical capabilities, barrier properties, and other characteristics of edible packaging films [20].…”

The packaging problem with petroleum-based synthetic polymers prompts the development of edible packaging films. The high value-added reuse of navel orange peel pomace, which is rich in bioactive compounds, merited more considerations. Herein, nanocellulose (ONCC) and soluble dietary fiber (OSDF) from navel orange peel pomace are firstly used to prepare dietary fiber-based edible packaging films using a simple physical blend method, and the impact of ONCC on the film’s properties is analyzed. Adopting three methods in a step-by-step approach to find the best formula for edible packaging films. The results show that dietary-fiber-based edible packaging films with 4 wt.% ONCC form a network structure, and their crystallinity, maximum pyrolysis temperature, and melting temperature are improved. What’s more, dietary-fiber-based edible packaging films have a wide range of potential uses in edible packaging.
