“…The signal at 1550 cm −1 is the amide-II, representing NH bending and CN stretching. The CH deformation at 1448 cm −1 and 1236 cm −1 are attributed to amide-III, associated with in-plane vibration of the CN and NH groups of the bonded amine together with oscillation vibrations of the CH 2 groups of the glycine skeleton and proline side chains [ 22 , 23 , 24 ]. Additional peaks were observed at 1035 cm −1 , 922 cm −1 and 850 cm −1 , which represent the interaction between the plasticizer (OH groups of glycerol) and the gelatin biofilm structure [ 25 , 26 ].…”

The objective of this work was to obtain biomaterials as gelatin films or biofilms produced by casting, reinforced with a microfiber (MF) from Agave angustifolia Haw bagasse and bentonite (BN) nanoparticles and evaluate the effect of such reinforcements at different concentrations. Agave microfibers were obtained by a non-abrasive chemical method. Three formulations based on gelatin with glycerol were reinforced with microfiber, bentonite and both materials with 1.5, 3.5 and 5.5% w/w solids content. Physicochemical properties were determined using SEM and FTIR, thickness, soluble matter and moisture. The XRD, barrier, mechanical and thermal properties were measured. The films’ micrographs showed agglomerations on the surface. Interactions between its functional groups were found. The solubility increased when the MF concentration increased. The thickness of the films was between 60 and 110 μm. The crystallinity ranged from 23 to 86%. The films with both MF and BN and 3.5% w/w solids had the lowest barrier properties, while the film with 5.5% w/w solids showed the highest mechanical properties, being thermally resistant. Overall, Agave microfibers together with bentonite were able to improve some of the films’ properties, but optimized mixing conditions had to be used to achieve good particle dispersion within the gelatin matrix to improve its final properties. Such materials might have the potential to be used as food packaging.

“…(small exothermic peak at 340°C For Hap_Gel, the exothermic effect at 235-430°C with the maximum at 335°C is attributed to the decomposition of Gel. 28 A total weight loss of 15.86% was observed ( Figure 4b); from 10 wt.% Gel only approximately 6 wt.% was detected, the other part probably being lost during the washing process.…”

This study evaluated the effect of different additives such as nanocarbon compounds (0.5, 1.0, and 2.0 wt.%) with different morphologies and gelatin (Gel) (10 wt.%) on the mechanical properties of hydroxyapatite (Hap)based nanocomposites (NCs). The NCs were prepared using the innovation process "SmartBox" based on the Internet of things (IoT), which provides process control and reproducibility, and they were characterized by X-ray diffraction, particle size distribution, transmission electron microscopy, Fourier transform infrared spectroscopy, and thermal analysis. The compressive strength tests demonstrated that the use of grapheme oxide (Hap_GO_2.0-133 N/mm 2) , and/or Gel (Hap_Gel-152 N/mm 2) as additives to reinforce Hap (106 N/mm 2) is more appropriate than the use of single functionalized multiwalled carbon nanotubes (Hap_fMWCNT_1.0-110 N/mm 2) and fullerene (Hap_Ful_0.5-106 N/mm 2) .

“…All lms including control gelatin lm showed excellent light barrier properties, speci cally in UVC (200-280 nm) region. This is due to the presence of chromophore groups such as tyrosine and phenylalanine amino acid groups in gelatin network, which have unsaturated bond that absorb UV radiation (Chuaynukul et al 2018). Addition of CNC to the gelatin lm, decreased the light transmittance in UV and Visible light radiation region to a considerable extent.…”

Herein, the leather waste-based gelatin composite film reinforced with cellulose II nanocrystal (CNC II) extracted from wet wipes using three different hydrolysis techniques is explored for its functional properties. CNC II isolated using peroxide (PCNC), citric acid (CCNC) and hydrochloric acid (HCNC) differed in morphological and crystalline character as investigated using DLS, FE-SEM, FTIR and XRD analysis. The crystallinity of PCNC, CCNC and HCNC was found to be 81.1%, 75.4%, and 86.1%, respectively. The highly crystalline CNC II (PCNC) incorporation improved mechanical stiffness of raw hide trimming waste-based gelatin films by 50% compared to control gelatin film. Maximum thermal stability with T max of 329 ºC was obtained for gelatin films with PCNC nano-reinforcement. Strong interfacial hydrogen bonding interactions between gelatin and cellulose II nanocrystal existed and modified the properties of the film. Incorporation of CNC II reduced the surface wettability of the films and absorbed UV radiation as evidenced by transmittance value T280 of 0.19. Nanocomposite films degraded up to 79.9% of initial mass under 7 days of soil burial. Single use packaging application of garden eggplant seed has been demonstrated.
