Gelrite-Gellan Gum Biopolymer Films Reinforced with AKBA derivative (SK-C5) for Biodegradable Food Packaging Applications

The current study explores the fabrication and characterization of gelrite gellan gum biopolymer films loaded with boswellic acid derivative (1-(4-Methoxyphenyl)-1H-1,2,3-triazol-4-yl) methyl) carbamoyl) 3α‐acetyloxy‐11‐oxo‐urs‐12‐en‐24‐oate (SK-C5). The synthesized SK-C5 was successfully integrated into the gelrite gellan gum films using the casting method. The physicochemical structural properties of the produced films were characterized. The obtained values were measured by using One-way ANOVA was used followed by Fisher’s post hoc test at a 5% significance level. The antioxidant activity of the patterned films improved via increasing the ABTS radical scavenging activity from 14.46% to 33.50% compared to its control sample. The incorporation of SK-C5 also led to an increase in the thickness and haze value of the film samples and a decrease in the transmittance and swelling index of the film samples. The functional group between the polymer and SK-C5 was observed by using FTIR spectroscopy. The mechanical properties of the films did not change significantly. Moreover, the surface hydrophobicity of the film surface was increased. The results indicate that boswellic acid derivatives-loaded biopolymer-based packaging material possess great a potential as active food packaging.
