Summary: CMC and pectin are two main polysaccharides with great potential in making edible coatings for fruits and vegetables. These coatings are commonly odorless, tasteless, non-toxic, non-allergic, water-soluble, transparent and resistant to oil and fats. They can also serve as carriers for active additives to prevent unwanted reactions and protect horticultural products during storage.

Summary: A novel composite film for food packaging was prepared using hydroxyethyl cellulose (HEC), carboxymethyl chitosan (CMCS), and zinc oxide nanoparticles by solution casting method. Spectroscopy, crystallography, and morphology observation confirmed the successful incorporation of nanoparticles. The addition of CMCS and ZnO improved the solvent resistance (reduced water solubility by 94.3%) and UV shielding ability (increased UV shielding capacity by 45.73%) of the film, enhancing its potential applications in water-rich foods. The composite film demonstrated efficient inhibition (>99.99% inhibition rate) of pathogenic bacteria Listeria monocytogenes and Pseudomonas aeruginosa, with the synergistic effect of CMCS and ZnO. Furthermore, CMCS and ZnO significantly enhanced the elasticity (494.34% improvement) and maximum load capacity (142.24% improvement) of the composite film.

Summary: Edible films and coatings are potential methods for preserving fresh food. Starch is commonly used for film and coating production due to its low cost and wide availability. However, additives are often needed to overcome the limitations of starch-based films. This review focuses on the effects of additives on the properties of starch-based films and coatings, and their compliance with the requirements for edible and biodegradable food packaging. The use of additives enhances the barrier properties and bioactivity of the films, and also improves their shelf stability.

Summary: In this study, a novel active packaging film (GCLF) was developed by mixing Gracilaria chouae polysaccharide (GCP) with carboxymethylcellulose (CMC) and lysozyme. The addition of 3% GCP improved the film's UV-light barrier capacity, modulus of elasticity, and tensile strength. The film matrixes had a tight and continuous microstructure with interactions between GCP, CMC, and lysozyme. Furthermore, the GCLF with 3% GCP prolonged the shelf life of bass, decreased microbial counts and volatile basic nitrogen content, and improved sensory acceptance. The GCLFs also showed no toxicity to cells in vitro. Overall, this study highlights the potential application of seaweed polysaccharides in food packaging.
