Summary: This study examined the properties of a new active packaging film developed by adding mulberry leaves polysaccharides (MLP) into carboxymethyl cellulose (CMC). The addition of MLP increased the thickness and roughness of the films, while decreasing the moisture content, water vapor permeability, and swelling degree. Increasing the concentration of MLP improved the mechanical properties of the films and enhanced UV light dispersion. The films exhibited good inter-molecular interaction between CMC matrix and MLP, as demonstrated by Fourier transform-infrared spectroscopy and X-ray diffraction. The prepared films showed excellent thermal stability, antioxidant and antibacterial properties, and biodegradability in the soil environment. Additionally, the films showed the ability to retard oil oxidation.

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.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
