Films are thin coatings of materials that protect the product against mechanical and corruption factors. The use of edible films and coatingsis developed these days because they can retain the quality, flavor and moisture content of the product and also are degradable and easy to use. Proteins are an apt choice for such film’s base material as their suitable barrier property against oxygen, CO2...

Plant-derived essential oils (EOs) and oil compounds usually have a relatively high vapor pressure and are capable of reaching microbial pathogens through the liquid and the gas phase. Bioactivity of EOs in the vapor phase makes them useful as possible fumigants for stored commodity protection. The use of edible films as carriers of natural antimicrobials constitutes an approach for external pr...

throughout the present, caseinate based edible films containing extracts of pomegranate peel were prepared in 3 levels of ×1, ×1.5 and ×2 (mic) and the physicomechanical, thermal, antimicrobial, and barrier properties of the films studied. to assess the microstructure changes resulting from the addition of the antimicrobial extracts, sem images were prepared from the surface and cross-section o...

Edible films were made from proteins (corn-zein and wheat gluten) and celluloses (methyl cellulose and hydroxypropyl cellulose), and tested fog permeability of gases. Oxygen and carbon dioxide permeabilities of edible films were generally lower than those of plastic films. However, water vapor permeabilities of edible films were higher than those of plastic films. The concentration of plasticiz...

Shelf life extension of Ricotta cheese was evaluated at 4 degrees C upon the use of edible coatings made of galactomannans from Gleditsia triacanthos incorporating nisin against Listeria monocytogenes. Three different treatments were tested in cheese: samples without coating; samples with coating without nisin; and samples with coating containing 50 IU x g(-1) of nisin. To test the effectivenes...

in this study the feasibility of using salep as a new film-forming material was studied. the mechanical properties, water vapor permeability and thickness of salep films incorporated with glycerol were determined. increasing the content of dry material of salep from 1% to 3%(w/v) increased values for tensile strength and elongation at break from 16.16% and 18.85 mpa to 70.15% and 24.50 mpa resp...

The development of edible coatings to extend the shelf-life of fresh fruits and vegetables has been one of the most important goals of the post harvest industry. Thus, in the last decade, research efforts have resulted in edible coatings based on biodegradable biopolymers (proteins and polysaccharides) that at the same time allow the reutilization of some by-products of the food industry. Gener...

Antimicrobial activity and the properties of edible film were studied by incorporating with encapsulated clove (Eugenia caryophyllata Thunb.) oil as a natural antibacterial agent. The minimal bactericidal concentration (MBC) of clove oil inhibited the growth of E. coli O175:H7, S. aureus and L. monocytogenes were tested in the stationary phase. The results showed that 1.0, 1.5 and 0.5% of clove...
