Edible films are manufactured from natural, renewable, nontoxic, and biodegradable polymers and are safe alternatives to plastic food packaging. Despite ongoing research, biopolymer-based edible films still are not at a quality to ensure total commercial replacement of synthetic packaging materials. The study aims to compare the effectiveness of some novel methods employed to improve edible film properties. These include dispersion of orange oil (1% & 2% v/v) and/or curcumin into guar gum (GG), glycerol and lecithin-based edible films that are further reinforced with Sodium trimetaphosphate (STMP) crosslinking with the aim enhancing films physical properties. The films were characterized by measurement of film thickness, density, moisture content, water dissolvability, FTIR Spectroscopy, opacity, water vapor permeability, tensile properties, and antimicrobial activity. Orange oil and curcumin preserved their antimicrobial activity inside the films, which bestowed the films with an active packaging function. Control GG films had acceptable tensile and barrier properties that were further improved. All other film properties, such as opacity, dissolvability, and moisture content, that should be designed for specific application, were successfully modified with the methods used. Our results confirm successful application of STMP crosslinking, emulsion film formation, and active agent addition to edible films in manufacturing GG films for packaging.

Preparation of antimicrobial films from agricultural biomass Seber, Ayşe Gizem; Bakır, Ufuk; Department of Biotechnology (2010) Mainly used food packaging materials are petro-chemical based polymers which present environmental problems since they are not biodegradable and ecologically sustainable. In this study, biodegradable biofilms are produced from xylan, extracted from cotton stalk which is an agricultural biowaste without nutritional value. Antimicrobial property was given to the biofilms with either titanium dioxide sol-gel coatings or titanium dioxide powder addition into the biofilm forming solutions. The antimicrobial acti...
The effects of microbial lignocellulose pretreatments on xylooligosaccharide production Uckun, E.; Ak, O.; Bakir, U. (Elsevier BV, 2009-09-01) Lignocellulosic agricultural waste materials are produced in huge amounts in the world and regarded as abundant, inexpensive readily available natural sources for various industries. They are mainly composed of three types of macromolecules, cellulose, hemicellulose and lignin. Cellulose and hemicellulose are converted to a variety of valuable compounds such as enzymes, hormones, antibiotics, ethanol, sugar alcohols, organic acids and xylooligosaccharides (XOs) using bioprocessing methods easily after the r...
A promising enzyme anchoring probe for selective ethanol sensing in beverages Soylemez, Saniye; Goker, Seza; Toppare, Levent Kamil (Elsevier BV, 2019-07-15) A newly designed amperometric biosensor for the determination of ethanol through one-step electrochemical coating of (4,7-di(thiophen-2-yl)benzo[c][1,2,5]selenadiazole-co-1H-pyrrole-3-carboxylic acid) (TBeSe-co-P3CA) on a graphite electrode is presented. It was aimed to propose a newly synthesized copolymer with enhanced biosensing properties as a novel sensor for the quantification of ethanol. The conjugated copolymer (TBeSe-co-P3CA) was prepared through electrochemical polymerization by potential cycling....
Production of an acetone-butanol-ethanol mixture from Clostridium acetobutylicum and its conversion to high-value biofuels Sreekumar, Sanil; Baer, Zachary C.; Pazhamalai, Anbarasan; Günbaş, Emrullah Görkem; Grippo, Adam; Blanch, Harvey W.; Clark, Douglas S.; Toste, F. Dean (Springer Science and Business Media LLC, 2015-03-01) Clostridium acetobutylicum is a bacterial species that ferments sugar to a mixture of organic solvents (acetone, butanol and ethanol). This protocol delineates a methodology to combine solventogenic clostridial fermentation and chemical catalysis via extractive fermentation for the production of biofuel blendstocks. Extractive fermentation of C. acetobutylicum is operated in fed-batch mode with a concentrated feed solution (500 grams per liter glucose and 50 grams per liter yeast extract) for 60 h, producin...
Pathogen detection by core-shell type aptamer-magnetic preconcentration coupled to real-time PCR Ozalp, V. Cengiz; BAYRAMOĞLU, GÜLAY; Kavruk, Murat; Keskin, Batuhan B.; Öktem, Hüseyin Avni; ARICA, MEHMET YAKUP (Elsevier BV, 2014-02-15) The presence of pathogenic bacteria is a major health risk factor in food samples and the commercial food supply chain is susceptible to bacterial contamination. Thus, rapid and sensitive identification methods are in demand for the food industry. Quantitative polymerase chain reaction (PCR) is one of the reliable specific methods with reasonably fast assay times. However, many constituents in food samples interfere with PCR, resulting in false results and thus hindering the usability of the method. Therefo...
