“…In fact, CMC-based films, as almost all biodegradable films, have low water resistance and present weak water vapor barrier properties, that make them frequently non-competitive when compared with other non-biodegradable polymers (Shahbazi et al, 2016). In this context, CMC-based films have been filled with other polymers aiming to improve these properties (Ibrahim and El Salmawi, 2013;Oun and Rhim, 2017).…”

Organosolv lignin was incorporated in carboxymethyl cellulose (CMC)-based films as a reinforcing and bioactive agent. Films were produced by the casting method using compatible and environmentally friendly solvents. The incorporation of lignin in CMC-based films was evaluated in term of morphology, physicochemical, barrier, mechanical and antioxidant properties. Solubility tests showed that lignin improved the water resistance of the films for approx. 60%. This behavior was also observed for the water vapor permeability, achieving a 20% reduction. Morphological characteristics suggested low compatibility between organosolv lignin and CMC matrix, revealed by the small aggregates homogeneously distributed in the film, through scanning electron microscopy, related to the self-assembly behavior of lignin. CMC/lignin-based films also presented higher thermal stability. Fourier transform infrared spectroscopy showed that incorporation of lignin led to small changes in the film's structure. Finally, organosolv lignin proved to be a promising material for the development of active CMCbased films due to its demonstrated antioxidant activity that can be useful to pack food products that suffer from undesirable oxidation reactions.

“…Because both SA and CMC are water‐soluble polymers, they are compatible as a result of the formation of hydrogen bonds. Blended CMC/SA films have been investigated as potential composites . However, both SA and CMC lack antibacterial properties, and so they fail to provide a barrier against infection by microorganisms, which restricts their use in food packaging areas.…”

“…The blend had comparatively weak hydrogen bonds acting on −OH groups, relative to pure pullulan. Crosslinked SA/CMC blends have been prepared by the casting solution method, under various gamma rays irradiation doses [3]. With increased irradiation both the gel fraction and the swelling ratio of SA/CMC blends increase, and the swelling also increases with increasing SA content.…”

Turmeric extract (tmr) loaded nanoparticles were prepared by crosslinking modified carboxylmethyl cellulose (CMC) and modified sodium alginate (SA) with calcium ions, in a high pressure homogenizer. The FTIR spectra of CMC and SA were affected by blending due to hydrogen bonding. The negative zeta potential increased in magnitude with CMC content. The smallest nanoparticles were produced with a 10 : 5 SA/CMC blend. Also the release rates of the extract loading were measured, with model fits indicating that the loading level affected the release rate through nanoparticle structure. The 10 : 5 SA/CMC blend loading with tmr and pure tmr showed a good % growth inhibition of colon cancer cells which indicate that tmr in the presence of curcumin in tmr retains its anticancer activity even after being loaded into SA/CMC blend matrix.
