Effect of Ethylene Glycol and Glycerol Concentrations on Properties of Rye-Based Films

Rye flour based edible films were produced by using glycerol and ethylene glycol as plasticizers at concentrations ranging between 40 to 100% (w/w of rye flour). The structural, mechanical, physical, chemical properties the investigated. results showed that increasing plasticizer concentration resulted in a greater thickness, water vapor permeability, solubility films. While permeability not affected type, thickness glyserol-containing was significantly higher. Good mechanical obtained for composites, where greatest tensile strength 7.47 MPa measured film containing 40% flour) highest elongation 69.3% observed increase added had an adverse effect on antioxidant activity total phenolic content films, due probable dilution composites.
