“…Regarding EB, no effect was observed with the addition of free curcumin and curcumin-loaded nanohydrogels to CMC-based films, suggesting that the rigid properties of CMC were more prevalent than the elongation properties of the free curcumin and curcumin-loaded nanohydrogel in the films. The same behavior was observed by da Silva [31], who encapsulated treated curcumin (native curcumin treated using antisolvent precipitation) in hydroxypropyl methylcellulose.…”

“…Regarding color, the most significant change between films was observed for a* and b*, which was related to chromatic coordinates. As observed in Table 2, CMC-based films with curcumin-loaded nanohydrogels showed higher b* values compared to CMC-based films and CMC-based films with free curcumin, indicating a color transiting to yellowness (b* = 10.36), which was expected because of the curcumin color influence in these films [31]. These results can be confirmed visually in Figure 1.…”

Carboxymethylcellulose (CMC)-based films can act as a protective barrier in food surfaces and a carrier of bioactive compounds, such as curcumin. However, incorporating curcumin in hydrophilic matrixes can be a challenge, and new strategies need to be explored. In this work, CMC-based films containing free curcumin and curcumin-loaded nanohydrogels (composed of lactoferrin and glycomacropeptide) were produced and characterized. The incorporation of curcumin-loaded nanohydrogels showed a significant decrease in films’ thickness (from 0.0791 to 0.029 mm). Furthermore, the water vapor permeability of CMC-based films was significantly decreased (62%) by incorporating curcumin-loaded nanohydrogels in the films. The water affinity’s properties (moisture, solubility, and contact angle) of films were also affected by incorporating encapsulated curcumin. The addition of nanohydrogels to CMC-based films reduced the tensile strength values from 16.46 to 9.87 MPa. Chemical interactions were analyzed using Fourier transform infrared spectroscopy. The release profile of curcumin from CMC-based films was evaluated at 25 °C using a hydrophilic food simulant and suggests that the release mechanism of the curcumin happens by Fick’s diffusion and Case II transport. Results showed that protein-based nanohydrogels can be a good strategy for incorporating curcumin in edible films, highlighting their potential for use in food applications.

“…From 3600 to 3000 cm -1 the broad band corresponded to the characteristic stretching of O-H and N-H bonds (Božič et al, 2012b;Liu, You, Tarafder, Zou, & Fang 2019). It was possible to see two peaks on the curcumin spectrum, one at 3510 cm -1 and the other one at 1279 cm -1 corresponding to the stretching and the bending of the phenolic -OH groups, respectively (Božič et al, 2012b;Liu et al, Ying, Cai, & Le, 2017;Nascimento da Silva, de Matos Fonseca, Feldhaus, Soares, & Valencia, 2019). Peaks located at 1600 and 1508 cm -1 corresponded to the stretching of the C=C bonds of the cyclic alkenes (Božič et al, 2012b;Hasan et al, 2016;Poljanšek, Šebenik, & Krajnc 2006).…”

“…Pure HPMC shows a broad peak at 3488 cm −1 , which is attributable to the axial stretching of ‐OH groups and hydrogen bonds between polymeric chains. [ 39 ] The peak at 2930 cm −1 corresponds to the C–H symmetric stretching vibration of hydroxypropyl groups. [ 40 ] Noticed weak relative peaks at 1377 and 1458 cm −1 belong to ‐OH bending and –CH 2 scissoring stretching modes from methyl groups.…”

Hydroxypropyl methylcellulose (HPMC) is blended with methyl gallate (MG) encapsulated with poly(ethylene glycol) (PEG) and then mixed with a liquid electrolyte to prepare a polymer gel electrolyte. The structural and physical properties of prepared polymer gels are analyzed by various analytical instruments. The MG‐PEG‐HPMC hybrid is found to be able for entrapping a large amount of liquid electrolyte and is used to fabricate dye‐sensitized solar cells (DSSCs). This polymer gel electrolyte shows high ionic conductivity (5.43 × 10−4 S cm−1) and good triiodide diffusion coefficient (2.25 × 10−6 cm2 s−1). The resulting DSSCs show an efficiency of 6.96% at a light intensity of 85 mW cm−2. The long‐term stability test reveals that the fabricated DSSCs will be stable even after 500 h. The benefits of incorporating a gel electrolyte into DSSCs are highlighted along with factors affecting the stability of these devices. The use of these bio‐based materials has the potential to make a significant contribution to the widespread exploitation of stable, efficient, and low‐cost dye‐sensitive solar cells.
