“…The antioxidant agents result in strong DPPH radical scavenging ability resulting in low lipid oxidation of the packaged food product. The reduced lipid oxidation and microbial growth results in reduced food spoilage, which ultimately leads to prolonged shelf-life of food products and increases the ability of food preservation [ 46 , 47 , 48 ]. Edible films can also be used as delivery systems for the controlled release of bioactive components, nutrients, pharmaceuticals, and food ingredients.…”

“…Tea polyphenols were added to the Gelatin–Sodium alginate film that increased the antioxidant activity of the film [ 43 ]. The addition of Ferulic acid to a Sodium alginate edible film increased the antioxidant capacity of the film by a few folds [ 47 ]. In addition, studies were conducted on Carrageenan films with the incorporation of different levels of olive leaf extract.…”

Food contact materials (FCMs) are materials that come in contact with food products such as food packaging which play a significant role in the food quality and safety. Plastic, which is a major food packaging material, harms the eco-system, wildlife, and the environment. As a result, numerous researches have been in progress on alternative polymers, which has similar properties as plastic but is also environmentally friendly (biodegradable). In recent years, the utilization of seaweed polysaccharides has piqued interest due to its biodegradability, non-toxicity, antioxidant capabilities, and excellent film formation ability. However, it has a number of drawbacks such as low tensile strength, water solubility, and moderate antibacterial characteristics, among others. The addition of other biopolymers, nanoparticles, or natural active agents improves these features. In this review article, we have summarized the current state of seaweed polysaccharide research in active packaging, intelligent packaging, edible films, and coatings. It also highlights the physical, thermal, antioxidant, and other properties of these materials. Finally, the article discusses the relevant legislation as well as the field’s future prospects. Research shows that seaweeds polysaccharide looks promising as a sustainable food contact material, but there is always a potential for development to make it market feasible.

“…Sodium alginate (SA) is an algal carbohydrate macromolecule with potential film-forming properties. It is an anionic copolymer of alginic acid including (1–4)-β-d-mannuronate and α-l-guluronate residues covalently linked together in different sequences [ 14 ]. SA is non-toxic, renewable, and biodegradable and can be used in the production of active coating as a polymer matrix for the substance to be released [ 15 ].…”

The research evaluated the effects of locust bean gum (LBG) and sodium alginate (SA) active coatings containing 0.15, 0.30 or 0.60% lemon verbena (Lippa citriodora Kunth.) essential oil (LVEO) on the bacterial diversity and myofibrillar proteins (MPs) of large yellow croaker during refrigerated storage at 4 °C for 18 days. Variability in the dominant bacterial community in different samples on the 0, 9th and 18th day was observed. Pseudomonas and Shewanella were the two major genera identified during refrigerated storage. At the beginning, the richness of Pseudomonas was about 37.31% and increased for control (CK) samples during refrigerated storage, however, the LVEO-treated samples increased sharply from day 0 to the 9th day and then decreased. LBG-SA coatings containing LVEO treatments significantly delayed MPs oxidation by retarding the formation of free carbonyl compounds and maintaining higher sulfhydryl content, higher Ca2+-ATPase activity, better organized secondary (higher contents of α-helix and β-sheet) and tertiary structures during refrigerated storage. The transmission electron microscope (TEM) images showed that the integrity of the sarcomere was damaged; the boundaries of the H-, A-, and I-bands, Z-disk, and M-line were fuzzy in the CK samples at the end of storage. However, the LVEO-treated samples were still regular in appearance with distinct dark A-bands, light I-bands, and Z-disk. In brief, LBG-SA active coatings containing LVEO treatments suggested a feasible method for protecting the MPs of large yellow croaker during refrigerated storage.
