Abstract EN
The physical, thermal, mechanical, optical, microstructural, and barrier properties of low-density polyethylene films (LDPE) containing ferula asafoetida leaf and gum extracts were investigated.
Results showed a reduction in elasticity and tensile strength with increasing extract concentration in the polymer matrix.
The melting temperature and enthalpy increased with increasing concentration of extracts.
The films containing extracts had lower L∗ and a∗ and higher b∗ indices.
The films containing leaf extract had more barrier potential to UV than the gum extracts.
The oxygen permeability in films containing 5% of leaf and gum extracts increased by 2.3 and 2.1 times, respectively.
The morphology of the active films was similar to bubble swollen islands, which was more pronounced at higher concentrations of gum and leaf extracts.
FTIR results confirmed some chemical interactions of ferula extracts with the polymer matrix.
At the end of day 14th, the growth rate of Aspergillus niger and Saccharomyces cerevisea in the presence of the PE-Gum-5 reduced more than PE-Leaf-5 (3.7 and 2.4 logarithmic cycles, respectively) compared to the first day.
Our findings showed that active LDPE films have desire thermo-mechanical and barrier properties for food packaging.
