To produce a unique active packaging film, Gracilaria chouae polysaccharide was prepared and mixed with carboxymethylcellulose and lysozyme in this research. 3% GCP could increase the film's UV-light barrier capacity by 61. 5 percent, modulus of elasticity by 47. 55 percent, and tensile strength by 56. 7 percent. The film matrixes were well entangled and had a tight and continuous microstructure, as shown by Scanning electron microscopy. The interactions between GCP, CMC, and lysozyme on film results were shown by a Fourier transform infrared spectrometer and differential scanning calorimeter. The addition of 3% GCP in the GCLF could extend the shelf life of bass. In addition, the GCLFs did not exhibit toxicity in vitro on ICE-6 cells. In a nutshell, GCP could be used as a film-forming material, increasing the film's modulus of elasticity and its preservation properties in sea bass. The research will expand the usage of seaweed polysaccharides in food packaging.

The addition of CMCS and ZnO enhanced the adhesive stability and UV shielding ability of the composite film, as well as increasing the application prospects of the film in water-rich foods. In addition, the synergistic action of CMCS and ZnO enabled the composite film to effectively reduce Listeria monocytogenes and Pseudomonas aeruginosa in food.

The effect of Co-MOF addition on the CMC film's fabric, physical, and functional characteristics was extensively investigated. The results revealed that the Co-MOF nanofillers were homogeneously embedded within the CMC matrix, bringing about a major improvement in tensile durability, toughness, water barrier, and UV blockage of CMC film. The CMC/Co-MOF nanocomposite films were then used for real-time video verification of shrimp freshness. The above results show that the CMC/Co-MOF nanocomposite films have a large potential for use in smart active packaging.

According to a more realistic CMC film, the OTR, WVTR, and tensile durability of CMC/ZIF composite film with 1 wt/ and 70. 1 MPa were improved from 64. 89 cm 3 *+, 1579. 21 g/ and 16. 9 MPa to 20. 79 cm/3 *u03bcm/, 20. 79 g/, 70. 1 MPa, respectively, to 20. 79 g/ and 70. 1 MPa,.

For fast hydroxymethyl furfural sensing in date molasses, novel biosensors based on carboxymethyl cellulose extract from date palm fronds containing Ag nanoparticles were developed. At different HMF concentrations, the sensing behavior of the prepared AgNPs@CMC electrode was investigated in terms of cyclic voltammetry and linear scan voltammetry. The findings showed high success of the engineered AgNPs@CMC, which was confirmed by the linear results of the correlation between the cathodic current and HMF data.

As an electrochemical working electrode for fast hydroxymethyl furfural measurement in date palm fronds, Novel biosensors based on carboxymethyl cellulose extract from date palm fronds containing Ag nanoparticles were assembled. At various HMF concentrations, the sensing behavior of the prepared AgNPs@CMC electrode was investigated in terms of cyclic voltammetry and linear scan voltammetry. The results showed high success of the prototype AgNPs@CMC, which was demonstrated by the linear relationship between the cathodic current and HMF content.

The film with 5 percent REO was chosen as the best film by the filmmakers with better mechanical characteristics in comparison to other emulsified samples containing REO. In addition, 5 % of REO contributed to the film's increased compactness when compared to the film without the REO. No new chemical bonds were established by adding REO to the biopolymer substrate, and the REO was easily dispersed and dispersed throughout the Gla-CMC chains throughout the film substrate, based on the results of Fourier-transform infrared spectroscopy spectra.
