Advantages of MAP for Food Packaging

INTRO
MAP or Modified Atmosphere Packaging is a widely
used technique of preservation when it comes to
food packaging. It is a notable method of
preventing spoilage and extending the shelf life
of various food products. Modified Atmosphere
Packaging and food tray sealing machines became
especially essential during the COVID-19 pandemic
which resulted in an extensive increase in demand
for packaged food products that were packed using
MAP technology.

What is MAP exactly?
Modified Atmosphere Packaging includes either
actively or passively modifying the atmosphere
surrounding the product in the interior of a
package made of various types and/or combinations
of films. Modified atmosphere packaging machines
India come in two kinds Passive and Active. An
active modified atmosphere packaging is the
process in which the displacement of gases in the
package is done and is then replaced with a
desired mixture of gases. A passive modified
atmosphere packaging is when the product is
packaged using a selected film type and the
required atmosphere develops on its own as a
consequence of the products respiration and
diffusion of gases through the film.

What is MAP exactly?
One of the major active MAP technologies in
Packaging solutions in India for food and
beverage products is gas flushing. A gas flush
is used for the following purposes
Displacement of oxygen inside the package to
delay oxidation
Decreasing the development of aerobic spoilage
organisms
Acting as a filler for maintaining package
conformity
During the gas flush procedure, a harmless gas -
usually nitrogen or carbon dioxide or both - is
dynamically pumped into the bag before it is
sealed in order to displace ambient oxygen. The
reason for this is to decrease the amount of
oxygen since it is the most damaging to the
freshness of the material.

The role of nitrogen and carbon dioxide

• Nitrogen, being an inert gas, is frequently used
  in nitrogen packing machines and nitrogen filling
  machines for food packaging to displace oxygen
  for products which are prone to oxidation. It
  also acts as a filler gas to prevent the pack
  from collapsing. Many snack products like potato
  wafers rely on nitrogen flushing to ensure longer
  shelf life, decrease rancidity and maintain the
  quality of the snacks.
• Carbon dioxide is generally inserted to act as an
  anti-microbial agent. A minimum amount of 20
  carbon dioxide is mixed with nitrogen to form
  anaerobic environments that inhibit the growth of
  aerobic microorganisms.

How does modified atmosphere packaging protect
food items?

• The primary way in which modified atmosphere
  packaging by a food tray packing machine protects
  fresh food is by decreasing its exposure to
  oxygen. The presence of oxygen leads to
  oxidation, which causes discolouration, spoilage,
  and change in flavour and texture. Decreasing or
  regulating the amount of oxygen present in a
  package can ensure that the food product remains
  fresh longer, thereby extending its shelf life
  and ensuring the consistency of the food products.

NICHROMES MAP OFFERINGS
One of Nichromes MAP offerings in Packaging
Machines India is the Athena Thermoforming Tray
Sealing Machine from Tecnovac, Italy. The Athena
machine is able to seal and pack in a protective
atmosphere of vacuum and gas all types of trays
and jars. Its strong stainless steel structure
and easy maintenance make the Athena ideal for
use in small and medium-sized companies. The
Athena horizontal packaging machine ensures that
the marketers of cut fruits vegetables, meat
fish, namkeen sweets, and ready to eat meals
like biryani are able to ensure that their
products stay safe and hygienic till they arrive
at the consumers table. The modified atmosphere
packaging machine works by extracting oxygen
carbon dioxide from the air of the trays, while
synchronously filling them with nitrogen or mixed
air to ensure that the food does not deteriorate,
after which, the tray is sealed well.
