  Development and Characterization of Starch/Microcrystalline Cellulose/Bentonite Intelligent Packaging Films Incorporated With Red Beet Peel Extract for Monitoring Chicken Freshness

  Gürler, Nedim

  This study presents the physical, mechanical, antioxidant, and application properties of films prepared by adding red beet peel extract to the starch/microcrystalline cellulose/bentonite clay polymer composites by casting method to monitor chicken breast freshness. The effects of bentonite in different proportions (0%, 1%, 5%, and 10%) were investigated. The structure of the films was elucidated by XRD, FTIR spectroscopy, and SEM for surface morphology of films. Regarding mechanical testing, the highest tensile strength starch/microcrystalline cellulose-1% bentonite film was 0.88 MPa. It was noticed that water vapor permeability (WVP) improved with the addition of bentonite. Films containing 10% bentonite clay showed a 27% decrease in water vapor permeability compared to films without clay. However, the swelling power of composites increased as the bentonite content increased. Additionally, with the addition of clay the films exhibited more opaque properties. Red beet peel extract was also incorporated to the polymer composite to monitor chicken breast freshness. The antioxidant properties of the films were accomplished using DPPH method. When red beet peel extract was incorporated into the polymer film, the highest DPPH scavenging activity increased by 50%. In summary, starch/microcrystalline cellulose/bentonite films can be used as pH-sensitive intelligent packaging for controlling the freshness of chicken breast.

  The fabrication of bilayer polylactic acid films from cross-linked starch as eco-friendly biodegradable materials: Synthesis, characterization, mechanical and physical properties

  Gürler, Nedim; Paşa, Salih; Hakkı Alma, M.; Temel, Hamdi

  In this study, pure potato starch (PPS) was purified from waste potato residual to fabricate cross-linked bilayer materials with the casting method. Malonic acid (MA) was employed to get cross-linked material from PPS as PPS-MA. Then polylactic acid (PLA) was also implemented onto PPS and PPS-MA to produce bilayer materials as PPS-PLA and PPS-MA-PLA. The obtained these bilayer films were characterized by FTIR, XRD, and TGA. The mechanical and physical applications such as water vapor permeability, water uptake, moisture content, solubility, and opacity were investigated. The biodegradation calculations were also done by the process of composting. It has demonstrated that each application onto PPS increased the mechanical features. However, elongation wasn't seen during the breaking test of PPS and PPS-MA films, whereas the PPS-PLA and PPS-MA-PLA films demonstrated 9.34% and 10.14% elongation at break that substantiates the structural durability against rupture, fragmentation, and feeble. Furthermore, the water vapor permeability, water uptake, moisture content, and solubility decreased but the opacity has increased.
