One of the most promising innovations in smart packaging being pursued by many companies
has been the use of nanotechnologies to develop antimicrobial packaging to prolong product
shelf-life (Meetoo 2011) and reduce the need for man-made preservatives (Sekhon 2010). One
material developed for potential food packaging applications is based on nanostructured silicon
with nanopores. The potential application includes detection of pathogens in food and variations
of temperature during food storage. Another relevant development is aimed at providing a basis
for intelligent preservative packaging technology that will release a preservative only when the
packaged food begins to spoil (ETC-Group
