چکیده انگلیسی
Starch (S)-flaxseed meal (FM) biofilms were prepared from potato and maize starch by incorporating FM up to 15% (dry solid basis) and using glycerol as plasticizer. The dynamic mechanical properties, tensile properties and water vapor permeability (WVP) of these films were measured. The storage modulus of both the starch (control) and starch-FM films decreased as temperature increased. Tan δ increased initially in all the films with increase in temperature until a peak value was reached which allowed the determination of glass transition temperature (Tg). Both tensile strength and Young's modulus of the starch-FM films increased with increase in the FM content. The WVP of the potato starch-FM films first increased to 2.261 (Ã105 g mâ2 hâ1 Paâ1) when FM content increased to 5% and decreased down to 1.832 (Ã105 g mâ2 hâ1 Paâ1) with further increase in the FM content to 15%. While the WVP values of the cornstarch and corn starch-FM films were not significantly (p > 0.05) different. The incorporation of FM increased the tensile strength, decreased the % elongation at break and increased the Tg.
