Innovative active packaging film from quince seed mucilage/alginate enriched with biosilica nanoparticles containing oak extract for prolonged meat shelf Life

Title : Innovative active packaging film from quince seed mucilage/alginate enriched with biosilica nanoparticles containing oak extract for prolonged meat shelf Life

Abstract:

Biosilica nanoparticles synthesized from rice straw and loaded with oak fruit extract were utilized as an additive in quince seed mucilage/alginate polymer blend films to develop an active, environmentally friendly, and sustainable packaging material. Incorporating OE@SiNPs into QSM/Alg-based films demonstrated significant antibacterial activities against the foodborne pathogenic bacteria S. aureus and E. coli. Additionally, the nanocomposite films, particularly those with 5 wt% OE@SiNPs filler content, exhibited remarkable free radical scavenging activities, achieving 100% ABTS and 40.9% DPPH scavenging, as well as substantial UV blocking capabilities of approximately 96.5% for UV-A and 99.7% for UV-B. Compared to the pristine QSM/Alg film, the nanocomposite films with 5% OE@SiNPs exhibited reduced tensile strength, decreasing from 32.7 to 24.8 MPa, but displayed an improvement in elongation at break, rising from 8.6% to 9.0%. The water contact angle was also significantly increased for all samples. Meat packaged in the nanocomposite films showed significantly reduced quality deterioration in terms of appearance, pH, thiobarbituric acid reactive substances, and total viable colony count during a 20-day storage period. The multifunctional nanocomposite films are expected to have great potential for use in active food packaging applications.
