A new antimicrobial bilayer film was developed using chitosan, cellulose, and nisin. Chitosan solution containing nisin (500 and 1000 mu g/mL) was prepared by sol-gel method and then the solution was coated on cellulose paper by dip coating method. A chitosan-cellulose film without antimicrobial had no inhibitory effect on Listeria monocytogenes, whereas, the incorporation of nisin made a significant increase (P<0.05) in antimicrobial characteristics of the films. Moreover, no significant differences were shown on antimicrobial activity of developed films during the storage at 4 degrees C for one month. However, the addition of nisin showed a significant increase in the swelling index and solubility of bilayer film. Scanning electron microscope images revealed a uniform coating of chitosan solution on cellulose paper. The FTIR analysis also confirmed successful introducing and binding of the nisin in double layer film. Films with 1000 mu g/mL of nisin completely inactivated the initial (similar to 5 log(10) CFU/g) counts of L. monocytogenes on the surface of Ultra-filter white cheese after storage at 4 degrees C for 14 days. We concluded that nanocomposite film of chitosan-cellulose containing nisin has novel antibacterial activity and can be used for packaging in cheese. (C) 2017 Elsevier B.V. All rights reserved.

UTILIZATION OF CURCUMIN AND BIODEGRADABLE POLYMERS IN INTELLIGENT AND ACTIVE FOOD PACKAGING
YILDIZ, Eda; Şümnü, Servet Gülüm; Kahyaoğlu, Leyla Nesrin; Department of Food Engineering (2022-12-21)
The main purpose of this study is to produce smart and active packages with curcumin using biodegradable polymers. To fulfill this aim, two different film making methods namely electrospinning and casting were used. Firstly, to take benefit of the halochromic properties of curcumin, it was encapsulated into chitosan/PEO based nanofibers to monitor food freshness. The average diameter of the fibers was found to be between 283 ± 27 nm and 338 ± 35 nm. It was concluded that increasing the chitosan amount in na...
Characterization of non-Fickian moisture absorption in thermosetting polymers
Güloğlu, Görkem Eğemen; Altan, M. Cengiz (2015-05-22)
© 2015 AIP Publishing LLC.A recently developed moisture absorption model for thermosetting polymers that combines the non-Fickian, diffusion hindrance effects and three-dimensional anisotropy is introduced. The hindered diffusion model is shown to predict both short term Fickian and long term anomalous moisture absorption behavior often observed in thermosetting polymers and their composites. The salient characteristics of long term moisture uptake such as the equilibrium moisture content and the effect of ...
Preparation and characterization of titania-silica-gold thin films over ito substrates for laccase immobilization
Eker, Zeynep; Karakaş, Gürkan; Department of Micro and Nanotechnology (2009)
The aim of this study was to immobilize the redox enzyme laccase over TiO2-SiO2-Au thin film coated ITO glass substrates in order to prepare electrochemically active surfaces for biosensor applications. Colloidal TiO2-SiO2-Au solution was synthesized by sol-gel route and thin film was deposited onto the substrates by dipcoating method. The cysteamine was utilized as a linker for immobilization of enzyme covalently through gold active sites. Preliminary studies were conducted by using invertase as model enzy...
Development of pea flour based active films produced through different homogenization methods and their effects on lipid oxidation
Yıldız, Eda; Şümnü, Servet Gülüm; Şahin, Serpil (Elsevier BV, 2021-02-01)
The objective of this study was to investigate the effects of gallic acid incorporation and homogenization method (high-speed homogenization and ultrasonication) on the physicochemical characteristics of pea flour based active films and the activity of the films against lipid oxidation. The water vapor permeability results of the active films increased by approximately 16% with the addition of gallic acid. Furthermore, active films had higher elongation and flexibility due to the plasticizing effect of gall...
Preparation and characterization of cost effective spray pyrolyzed absorber layer for thin film solar cells
Sankir, Nurdan D.; Aydin, Erkan; Unver, Hulya; Uluer, Ezgi; Parlak, Mehmet (Elsevier BV, 2013-09-01)
In this study, highly (1 1 2) oriented crystalline copper indium disulfide (CuInS2) thin films with high mobility have been deposited via ultrasonic spray pyrolysis. Structural and electrical properties of CuInS2 thin films were examined to utilize them in solar cell applications. Various amounts of precursor solution ranging from 0.25 to 2.02 ml/cm(2) were used to form CuInS2 thin films onto the soda lime glass substrates. Scanning electron microscopy (SEM) analysis revealed that all sprayed films were pin...
