Book Part Citation - WoS: 12Citation - Scopus: 16Zein and Its Composites and Blends With Natural Active Compounds: Development of Antimicrobial Films for Food Packaging(Elsevier Ltd., 2016) Yemenicioğlu, AhmetIn this chapter the current developments in using biopolymer zein for active edible film-making are discussed with particular emphasis on antimicrobial packaging. Recent studies have showed the possibility of developing effective antimicrobial edible packaging materials through the incorporation of different natural antimicrobial compounds, including antimicrobial enzymes, peptides, and phenolic compounds, into zein films. The zein-based films that contain antimicrobial enzyme lysozyme and bacteriocin nisin have great potential as antilisterial edible packaging materials. Additionally, zein-based films that contain natural phenolic compounds might be suitable for antimicrobial, antioxidant, and/or bioactive packaging. The use of composites of zein with waxes and blends of zein with fatty acids enables researchers to obtain antimicrobial zein-based films with controlled release properties.Article Citation - WoS: 76Citation - Scopus: 95Development of Flexible Zein-Wax Composite and Zein-Fatty Acid Blend Films for Controlled Release of Lysozyme(Elsevier Ltd., 2013) Arcan, İskender; Yemenicioğlu, AhmetThe aim of this study was controlled release of lysozyme by modification of hydrophobicity and morphology of zein films using composite and blend film making methods. The incorporation of beeswax, carnauba or candelilla wax into films at 5% (w/w) of zein gave composite films containing amorphous wax particles, while incorporation of oleic acid into film at 5% of zein caused formation of blend films containing many spherical zein capsules within their matrix. The lysozyme release rates of composites reduced as the melting point of waxes increased. The composites and blends showed 2.5 to 17 fold lower lysozyme release rates than controls. The films were effectively plasticized by using catechin. The catechin also provided antioxidant activity of films (up to 69 mu mol Trolox/cm(2)) and contributed to their controlled release properties by reducing film porosity. The films showed antimicrobial activity against Listeria innocua. This work showed the possibility of obtaining advanced edible films having flexibility, antimicrobial and antioxidant activity and controlled release properties.
