Physicochemical properties of gelatin/silver nanoparticle antimicrobial composite films.

Kanmani P1, Rhim JW.Author information 1Department of Food Engineering and Bionanocomposite Research Institute, Mokpo National University, 61 Dorimri, Chyungkyemyon, Muangun 534-729, Jeonnam, Republic of Korea.AbstractActive nanocomposite films were prepared by blending aqueous solutions of gelatin with different concentrations of silver nanoparticles (AgNPs) using a solvent casting method. Formation of silver nanoparticles in the solution and films was confirmed with the surface plasmon resonance (SPR) band at 400-450 nm, measured by UV-vis absorption spectroscopy. The incorporation of AgNPs slightly affected the physical and mechanical properties of the films. Increase in the concentration of AgNPs resulted in a substantial decrease in water vapour permeability (WVP) and tensile strength (TS) of the gelatin films. Energy dispersive X-ray (EDX) spectroscopy and X-ray diffraction (XRD) analysis confirmed the presence of elemental silver and crystalline structure of the AgNPs in the gelatin film. Microscopic surface structure and thermal properties of the films were also examined by FE-SEM and thermogravimetric analysis. Gelatin/AgNPs nanocomposite films exhibited strong antibacterial activity against food-borne pathogens. Gelatin/AgNPs nanocomposite films are expected to have high potential as an active food packaging system to maintain food safety and to extend the shelf-life of packaged foods.

Development of a new evaluation method for gelatin film sheets.

Kamiya S1, Nagae K2, Hayashi K3, Suzuki N3, Hayakawa E3, Kato K3, Sonobe T4, Nakashima K2.Author information 1Faculty of Pharmaceutical Sciences, Nagasaki International University, 2825-7 Huis Ten Bosch, Sasebo, Nagasaki 859-3298, Japan. Electronic address: kamiya@niu.ac.jp.2Faculty of Pharmaceutical Sciences, Nagasaki International University, 2825-7 Huis Ten Bosch, Sasebo, Nagasaki 859-3298, Japan.3FUJI CAPSULE CO., LTD., 4242-1 Kitayama, Fujinomiya, Shizuoka 418-0112, Japan.4Miyagi University, 1-1 Yamato, Kurokawa, Miyagi 981-3298, Japan.AbstractGelatin film sheets are often used to form the shell in soft capsules prepared using the rotary die method. Examination of the film sheet properties is extremely important when materials other than gelatin are used. We examined the relationship between the width and the tensile strength of the gelatin film sheet in order to establish the required indexes of the gelatin film sheets. The coefficients of correlation (R) of the linear regressions 4 and 15 min after preparation of the gelatin film sheets were 0.9858 and 0.9167, respectively. These results suggest that the tensile strength decreased when the width of the gelatin film sheet increased. Subsequently, we examined the relationship between time and the tensile strength. We observed new phenomenon: the tensile strength of the gelatin sheets increased with time, following two phases. The first phase corresponded to over phase transition point at 4, 8, and 15 min and the second phase corresponded to under transition point at 15, 30, and 60 min. The R values were 0.9952 (4, 8, 15 min) and 0.9494 (15, 30, 60 min).

Barrier, structural and mechanical properties of bovine gelatin/chitosan blend films related to biopolymer interactions.

Benbettaïeb N1, Kurek M, Bornaz S, Debeaufort F.Author information 1National Center for Nuclear Sciences and Technologies, Sidi Thabet Technopark, 2020, Ariana, Tunisia; UMR PAM-PAPC Food Processing and Physico-Chemistry Laboratory, 1 esplanade Erasme, University of Burgundy/Agrosup Dijon, F-21000, Dijon, France.AbstractBACKGROUND: The increased use of synthetic packaging films has led to a high ecological problem due to their total non-biodegradability. Thus, there is a vital need to develop renewable and environmentally friendly bio-based polymeric materials. Films and coatings made from polysaccharide polymers, particularly chitosans and gelatins have good gas barrier properties and are more and more envisaged for applications in the biomedical and food fields, as well as for packaging. Casting method was used to develop edible plasticized film from chitosan and gelatin. Aiming to develop a blend film with enhanced properties, the effects of mixing chitosan (CS) and gelatin (G) in different proportions (CS:G, 75:25, 50:50, 25:75, w:w) on functional and physic-chemical properties have been studied.
