Starch based film is considered an economical and environmentally-friendly material for antimicrobial packaging. This study aimed at the development of food packaging from corn starch incorporated with methanol extract of plumbago zeylanica root as antimicrobial agents. The antimicrobial activity of the extract was tested on three bacterial strains namely Staphylococcus aureus, Salmonella typhi, E. coli and one fungal strain known as aspergilla niger. Inhibition of bacterial growth was examined using zone of inhibition test on solid media. For this 200 μl of various concentrations, 200mg/ml 100mg/ml, 50mg/ml and 25mg/ml plant extract were added into 8 mm hole diameter using micropipette. Hence 200μl of 200mg/ml extract could inhibit 13.5, 8.75, 10.5 and 27 mm diameter for Salmonella typhi, E. coli, staphylococcus aureus and Aspergilla niger respectively. Minimum inhibitory concentration was determined involving broth dilution method.</dc:description> <dc:identifier>https://zenodo.org/record/2343</dc:identifier> <dc:identifier>10.20372/nadre:2343</dc:identifier> <dc:identifier>oai:zenodo.org:2343</dc:identifier> <dc:relation>doi:10.20372/nadre:2342</dc:relation> <dc:relation>url:https://nadre.ethernet.edu.et/communities/aau</dc:relation> <dc:relation>url:https://nadre.ethernet.edu.et/communities/zenodo</dc:relation> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>http://www.opendefinition.org/licenses/cc-by</dc:rights> <dc:title>Production and Characterization of Starch Based Antimicrobial Packaging Film through Incorporation of Plumbago Zeylanica (Amira) Root Crude Extract</dc:title> <dc:type>info:eu-repo/semantics/doctoralThesis</dc:type> <dc:type>publication-thesis</dc:type> </oai_dc:dc>
