Antimicrobial activity of nisin incorporated in pectin and polylactic acid composite films against Listeria monocytogenes
An extruded composite food packaging film containing pectin, polylactic acids (PLAs) and nisin was developed to inhibit Listeria monocytogenes. The mechanical properties and surface structure of the film were also examined. Cells of L. monocytogenes were reduced by 2.1, 4.5 and 3.7 log units mL by the pectin plus PLA (pectin ⁄PLA) film containing nisin (1000 IU mL of tested liquid) in Brain Hea...
متن کاملMolluscicidal activities of curcumin-nisin polylactic acid nanoparticle on Biomphalaria pfeifferi
BACKGROUND Snail intermediate host control is a widely canvassed strategy for schistosomiasis control in endemic countries. While there have been increasing studies on the search for potent molluscicides in the past years, the use of nanoparticulate agents as molluscicides is yet to gain wide attention. The aim of this study was to assess the molluscicidal potential of curcumin-nisin poly lacti...
متن کاملBiodegradable polylactic acid polymer with nisin for use in antimicrobial food packaging.
Biodegradable polylactic acid (PLA) polymer was evaluated for its application as a material for antimicrobial food packaging. PLA films were incorporated with nisin to for control of foodborne pathogens. Antimicrobial activity of PLA/nisin films against Listeria monocytogenes, Escherichia coli O157:H7, and Salmonella Enteritidis were evaluated in culture media and liquid foods (orange juice and...
متن کاملPolylactic acid (PLA)
This website provides an excellent overview of PLA as a polymer, its properties, and manufacture. This web article describes the production of lactic acid from biomass by microbial fermentation coupled to a poly-merization process to make PLA. The article is a bit dated and its industrial projections are now seen to be a bit over-optimistic. NatureWorks is the company that started large-scale p...
متن کاملInactivation of Listeria monocytogenes in skim milk and liquid egg white by antimicrobial bottle coating with polylactic acid and nisin.
This study was to develop an antimicrobial bottle coating method to reduce the risk of outbreaks of human listeriosis caused by contaminated liquid foods. Liquid egg white and skim milk were inoculated with Listeria monocytogenes Scott A and stored in glass jars that were coated with a mixture of polylactic acid (PLA) polymer and nisin. The efficacy of PLA per nisin coating in inactivating L. m...
