The application of petroleum polymers and plastics in food packaging is exhibiting an increasing trend, due to low price and desirable characteristics. Nevertheless, these polymers are nonbiodegradable, nonrenewable, and require landfills. Edible polymers are suitable alternative for synthetic polymers, which can be consumed by animals or human beings without health risk. Edible packaging can protect the foodstuff from microbial and chemical deterioration during storage and distribution, which can lead to extend the quality and safety of packaged food. The plant gums as natural polymers are able to form films and coatings with good barrier properties against the transfer of gases such as oxygen, carbon dioxide, and moisture. This review summarized the production and characteristics of novel edible films and coatings based on plant gums such as tree exudate, seed, and tubers. K E Y W O R D Sedible films and coating, physico-mechanical properties, seed gum, tree exudates, tubers gums | INTRODUCTIONOver recent decades, the increasing application of synthetic polymers for food packaging caused some health and environmental concerns. 1 Polyethylene (PE), polyethylene terephthalate (PET), polypropylene (PP), polystyrene (PS), and polyvinyl chloride (PVC) are plastics used widely in food packaging due to their low cost, excellent resistance, and superior water barrier and protective features. Nevertheless, plastics are nondegradable and some of them are not recyclable and cause environmental consequences. To overcome these obstacles, the convincing solution is the application of biodegradable polymers. 2 Biodegradable polymers are substances that decompose into water, carbon dioxide, methane, mineral compounds, and biomass in nature. 3 Some of the polymers including polycaprolactone (PCL), polyglycolide (PGA), and polybutylene succinate adipate (PBSA) are biodegradable, but they are synthetic and produced from fossil sourced chemicals that are nonrenewable. 2 Biopolymers, promising alternatives for synthetic polymers, are classified into three groups according to their sources including biopolymers derived from biomass (eg, polysaccharides, proteins, and lipids), biopolymers synthesized from bio-derived monomers (eg, polylactic acid), and biopolymers provided by microorganisms (eg, gellan and pullulan). 3 The new approach in food packaging is the application of films and edible coatings based on biopolymers to extend the shelf-life and maintain food quality. 1,4 The edible coating is a thin layer of biopolymers applied directly in liquid form on the surface of foods by immersing or spraying method, whereas a film is prepared separately as a solid sheet, then applied as a wrapping on or between food products, as illustrated in Figure 1. 5,6 Films and coatings have been used to prevent dehydration and add shin to fruits and vegetables since the 20th century. In addition to their selective gas and moisture barrier properties, they can act as a carrier of coloration, flavoring, sweetener, antimicrobial, and antioxidant agen...

“…The term ‘bioactive films’ is mostly used by the scientific community to describe edible films loaded with bioactive compounds capable of promoting beneficial effects for health [ 7 , 41 , 42 , 43 ]. However, some studies have used this terminology to describe active films that have beneficial effects on food, such as antimicrobial and antioxidant activities [ 44 , 45 , 46 , 47 , 48 ].…”

Edible packaging has been developed as a biodegradable and non-toxic alternative to traditional petroleum-based food packaging. Biopolymeric edible films, in addition to their passive protective function, may also play a bioactive role as vehicles for bioactive compounds of importance to human health. In recent years, a new generation of edible food packaging has been developed to incorporate ingredients with functional potential that have beneficial effects on consumer health. Curcumin, a bioactive compound widely used as a natural dye obtained from turmeric rhizomes (Curcuma longa L.), has a broad spectrum of beneficial properties for human health, such as anti-inflammatory, anti-hypertensive, antioxidant, anti-cancer, and other activities. To demonstrate these properties, curcumin has been explored as a bioactive agent for the development of bioactive packaging, which can be referred to as functional packaging and used in food. The aim of this review was to describe the current and potential research on the development of functional-edible-films incorporating curcumin for applications such as food packaging.

“…Oliveira-Alcântara et al ( 90 ) developed synbiotic edible films based on bacterial cellulose/cashew gum containing 2% fructooligosaccharide (FOS) and Bacillus coagulans . It was pointed out that the addition of probiotics decreased the film strength and increased elongation explained by plasticizing effect and reducing intermolecular bonds between neighbor polymer chains resulting in increasing film flexibility and decreasing strength.…”

Edible films and coatings have gained significant consideration in recent years due to their low cost and decreasing environmental pollution. Several bioactive compounds can be incorporated into films and coatings, including antioxidants, antimicrobials, flavoring agents, colors, probiotics and prebiotics. The addition of probiotics to edible films and coatings is an alternative approach for direct application in food matrices that enhances their stability and functional properties. Also, it has been noted that the influence of probiotics on the film properties was dependent on the composition, biopolymer structure, and intermolecular interactions. Recently, the incorporation of probiotics along with prebiotic compounds such as inulin, starch, fructooligosaccharide, polydextrose and wheat dextrin has emerged as new bioactive packaging. The simultaneous application of probiotics and prebiotics improved the viability of probiotic strains and elevated their colonization in the intestinal tract and provided health benefits to humans. Moreover, prebiotics created a uniform and compact structure by filling the spaces within the polymer matrix and increased opacity of edible films. The effects of prebiotics on mechanical and barrier properties of edible films was dependent on the nature of prebiotic compounds. This review aims to discuss the concept of edible films and coatings, synbiotic, recent research on synbiotic edible films and coatings as well as their application in food products.
