Abstract:
The objective of the presented work was to develop, characterize and evaluate the biodegradable, proactive, protective, novel active packaging blend films of low methoxy pectin and sodium alginate and identify their antimicrobial and antioxidant ability with plant-based natural phytochemicals like cinnamaldehyde. Different blend films were prepared in different ratio like (75% pectin ± 25% sodium alginate) (100% pure pectin), (100% pure sodium alginate), (100% Pectin+200µL cinnamaldehyde), 75% pectin+25 sodium alginate+700µL cinnamaldehyde), The antimicrobial activity was tested against foodborne pathogens E. coliO157:H7 (MTCC 90), and Salmonella Typhi (MTCC 733) and zone of inhibition were recorded. On the basis of linear correlation analysis (R2), the free radical scavenging activity of 10% bio-composite incorporated with 0.30% cinnamaldehyde blends was 0.9235 for DPPH scavengers where citric acid were used as a positive control. The film was characterized by TGA, DSC, FTIR, and XRD analysis result was shown a significant effect on thermal behavior.
