Mechanical and barrier properties of rice bran films
Biodegradable films were prepared from rice bran, and their water vapor and oxygen permeabilities, mechanical properties and solubilities were studied. No differences in apparent water vapor permeability (WVP(APP)) were observed between rice bran films cast at pH 9.5 (RBfilm 9.5) and those cast at p...

Zusammenfassung: | Biodegradable films were prepared from rice bran, and their water vapor and oxygen permeabilities, mechanical properties and solubilities were studied. No differences in apparent water vapor permeability (WVP(APP)) were observed between rice bran films cast at pH 9.5 (RBfilm 9.5) and those cast at pH 3.0 (RBfilm 3.0). Rice bran films had higher WVP(app) and oxygen permeability when compared to a polyvinylidene chloride film. RBfilm 3.0 had lower oxygen permeability compared to RBfilm 9.5. Puncture strength, tensile strength, breaking factor, and protein solubility of RBfilm 9.5 were higher than those of RBfilm 3.0. A positive correlation (r = 0.91) was observed between puncture strength and tensile strength of films |
