Packaging films prepared from hot acid vs ultrasound-assisted microwave extracted pectin: a comparative study

Key Points

• Packaging films made from pectin showed different physical properties, highlighting the influence of extraction methods.
• The acid-extracted pectin films had a tensile strength of 15.2 MPa, while ultrasound-assisted films reached 12.5 MPa.
• Assessment using comparative analysis across extraction techniques evaluates the potential of pectin in packaging applications.
• Implications of this study suggest that pectin extraction methods significantly affect packaging film performance properties.
