“…Also, many of the earlier reports suggested that the TS of gelatin films increased with an increasing MMT concentration [13,18]. It was also further evident that the incorporation of MMT within the gelatin molecules leads to unfold the gelatin molecule by hydrogen bonding [28].…”

“…But, increase in protein (3-5%), plasticizer (20-40%) and MMT (0.25-0.75%) concentrations did not influence the TS (p>0.05). A decrease in the TS of gelatin films with the addition of sorbitol has been observed by some workers [18,24] due to reduced intermolecular bonds between gelatin chains [25].

“…The EAB and YM were calculated based on the maximum length extended at rupture and stiffness of the film, expressed in % and MPa, respectively. The thickness of the films were measured using micro screw gauge (Labtech International, Ambala, Haryana, India) at six random positions as described by the method of Jeya Shakila et al [18].…”

“…The WVTR of the gelatin films was measured as per the standard ASTM (American Society for Testing and Materials) method [22] as described by Jeya Shakila et al [18]. The gelatin film was cut into 0.90 x 0.90 cm pieces and each piece was put onto a permeability cup.…”

“…In our earlier study, multi-composite gelatin films were developed with the addition of MMT and chitosan using sorbitol as a plasticizer [18] but the individual effect of these variable factors on the film properties were not assessed. This study was therefore undertaken to examine the effect of four variable factors such as gelatin, sorbitol, MMT and chitosan on the mechanical, barrier and physical properties of the multi-composite films formed from shark catfish gelatin using response surface methodology (RSM).…”

The effects of four variable factors such as protein, sorbitol, montmorillonite (MMT) and chitosan on the properties of multi-composite shark catfish skin gelatin films were evaluated based on Response Surface Methodology (RSM). Incorporation of chitosan had positive effect on tensile strength, Young's Modulus and water vapor transmission rate (p<0.05). On the other hand, chitosan and MMT had decreased the elongation of the films (p<0.05). The transparency of the gelatin film was increased by the addition of gelatin and chitosan, whereas it was decreased by the addition of MMT. From the present study, it may concluded that gelatin films with good mechanical and barrier properties could be achieved with 4.50% gelatin, 25% sorbitol, 0.37% MMT and 3.25% chitosan. Thus, multicomposite gelatin films with any desirable properties could be formulated based on the results of the response surface methodology and these films shall be suitable for edible films or coatings for fish and other food products in food processing industries.
