is the process by which a
) product (typically
or pharmaceutical) is packaged in a
sterile container in a way which maintains sterility
Sterility is achieved with a flash-heating process (temperature
between 195° and 295°F (91° to 146°C)),Aseptic Packaging Council.
Questions & AnswersAseptically
retains more nutrients and uses less energy than conventional
sterilization techniques such as retort or hot-fill canning.
Aseptic food preservation
allow processed food
to keep for
long periods of time without preservatives
, as long as they are not opened.
The aseptic packages are typically a mix of paper
(LDPE) (24%), and aluminum
(6%), with a
tight polyethylene inside layer. Together the materials form a
tight seal against microbiological organisms, contaminants, and
degradation, eliminating the need for refrigeration
aseptic filling plant for milk was presented in
Switzerland in 1961.
company later became one of the leading suppliers of
processing and packaging equipment for dairies
. Aseptic techniques were common in Europe and
Asia before they were introduced in the United States in the
Aseptic containers may range in size from a few fluid ounces to a
nearly 8-million-gallon aseptic tank on an ocean-going ship.
Aseptic processing makes worldwide export and import of new,
economical and safe food products possible. Bag-In-Box
technology is commonly used because it
provides strong containers that are light weight and easy to handle
prior to being filled. Other common package types are drink boxes
In 1991, the Institute
of Food Technologists
rated the top 10 innovations in food technology
. Aseptic processing and
packaging ranked No. 1, ahead of juice concentrates, safe canning
and food fortification. In 2007
Dr. Philip E. Nelson
received the World Food Prize
in recognition for his
pioneering work in aseptic processing and bulk storage.
Aseptic processing is commonly used for packaging
of fruit juices, liquid whole eggs,
gravies, and tomatoes. Fresh tomatoes are aseptically processed and
packaged for year-round remanufacture into various food
Aseptic containers are recycled with a method called
hydrapulping.Aseptic Packaging Council. Recycling and Aseptic Packaging Frank Ackerman
comments that some plastics
and aseptic packages come out looking "relatively good" in overall
costs, while reminding that no packaging is always better. The
major problem, however, is that the hydrapulping facilities are not
that common, and thus the multimaterial packages are relatively
difficult to recycle. Tetra Pak, a notable company in the industry,
has launched an initiative to increase the recycling of aseptic
containers. A 1995 book on recycling notes that aseptic containers
were not widely recycled. In 1993, aseptic packages could be
recycled in 19 US states. Confusion over whether aseptic packages
can be recycled led to a 1990 ban on them in Maine.
