Abstract
Antimicrobial plant extracts used in food packaging
provide a healthy packaging alternatives. They contain
aromatic and phenolic compounds that are responsible for
their antibacterial properties. In this study, we report
the antibacterial effects of extracts obtained from sea
buckthorn (Hippophaë rhamnoides L.) leaves, and inner
bark of pine trees (Pinus silvestris) that were applied
as coatings on paper suitable for packaging application.
Extracts from sea buckthorn leaves exhibited
antibacterial effect both as a solvent extract and as a
coating on paper against Pseudomonas aeruginosa as test
bacteria. However, coatings of pine bark extract did not
exhibit antibacterial effect as coatings even though the
solvent extracts exhibited antibacterial effects.
Staphylococcus aureus demonstrated resistance towards
both plant extracts after they had been applied as
coatings on paper for packaging.
