MAP modified atmosphere packaging

for food packages

Most food tastes good at the beginning of preparation. But the process
of production, finishing and distribution makes it impossible for food
to be sold and consumed completely in this period of time. As a result,
producers must find ways to keep food fresh, from factories to stores and
consumers' tables. How can modified atmosphere packaging keep different
foods fresh? Shandong Kangbeite Packaging gives you an analysis of how
some common foods are kept fresh through modified atmosphere packaging.

Modified atmosphere packaging for preservation of bread

When dealing with bread products, we
must pay attention to some facts. The
more water content, the more difficult
it is to keep bread for a long time.
The problem of bread preservation is
mould. Mould growth requires oxygen,
which also dries bread. So oxygen is
the enemy of bread storage. So be
careful that there is no or very little
oxygen in the bread package. This is easy to achieve through carbon dioxide
gas packaging, but care must be taken to detect whether the packaging leaks

Modified atmosphere packaging of cheese

When it comes to cheese, you might think that
bacteria are part of good cheese. But in fact,
good cheese depends on the type of bacteria. Some
bacteria are good for cheese, others are bad for
cheese. Rule of thumb: Hard cheese with low
moisture content is prone to be invaded by mould,
while cheese with high moisture content is prone
to bacteria. Packing with pure carbon dioxide
prevents bacteria from growing. The soft cheese
and chopped cheese scheme is a combination of nitrogen and carbon dioxide

to ensure its original form, because the storage of carbon dioxide
environment will form a vacuum effect around the cheese packaging, which
we do not want to see.

Modified Atmosphere Packaging for Fresh-keeping of Coffee

The main enemy for coffee storage is oxygen. When coffee is roasted, it
produces a lot of volatile oil. If coffee is exposed to oxygen, the oil
oxidizes, causing the coffee to smell rotten. Therefore, coffee packaging
must avoid oxygen. At this time, if nitrogen is chosen, the coffee taste
period will be prolonged, which is a win-win situation.

Modified Atmosphere Packaging for Fish and Seafood

The key to keeping fish and seafood fresh is
to keep them cool. No, it's freezing - close
to zero degrees Celsius. But even if you have
a temperature of zero degrees Celsius,
seafood will still decay slowly.

Bacteria in fish can change the color of the
fish and gradually give off a bad smell. Oxygen is an enemy, because many
bacteria are aerobic, meaning they can multiply in an oxygen environment.
But oxygen is also the key to keeping fish fresh. So find a balance between
oxygen and carbon dioxide.

For MAP modified atmosphere packaging in food packing and storage, the
most important part is to find the right air mix ratio for your product,
and this may need some test and experiment before you make it a process
regulation of your business.
