8 frequently asked questions in MAP modified
atmosphere packaging
Modified atmosphere packaging technology is already utilized in the
packaging of many food products, including fresh meat, aquatic products,
other meat products, bakery products, ready made meals, etc. But for some
customers, the lack of essential knowledges in MAP technology is still
a problem. Below we list 8 frequently asked questions in the use of
modified atmosphere packaging.
1. How to extend the shelf life of our products by using the modified
atmosphere packaging technology?
Temperature, cleanliness, packaging and mixed gases ratio are all factors
that determine the shelf life of food. Usually, the shelf life of the
products can be increased by several days to several weeks under the best
possible environment.
2. Can I freeze the food packaged in modified atmosphere packages?
Sure. However, when food stored in a box/bag melts, your product loses
a lot of moisture and looks less fresh and delicious. Also, make sure that
the packaging material you use is suitable for freezing.
3. When I open the food package, I smell something special. Why does this
happen?
In most cases, food packaged correctly in any packages will have some
smells after package opened, which is a normal phenomenon. Each food
product releases its own volatile gas, which accumulates in the headspace.
Open the package and wait for a minute. If the taste hasn't been exhausted,
the quality of the product needs to be tested.
4. What kind of gas or mixture ratio is used in cooked meat?
Meat can be cooked successfully in CO2 and N2 environments. The mixing
ratio should refer to different meat types and meat cutting methods.
5. What mixture should we use?
The type of gas mixture depends on the type of food, the shelf life you
plan and the user of the product. Some accurate data need to be
experimented to tell you what kind of gas mixture you need.
6. Why is there water vapor condensation in our modified atmosphere
packaging?
The possible reason for water vapor condensation is the difference between
product temperature and storage temperature. We can add transparent
fog-proof film to the package. The product should be kept at a fairly low
temperature in the packaging process and at this temperature or lower in
the storage process. Packing should also be puncturable so as to check
the residual oxygen in the package.
7. Why does Modified Atmosphere Packaging Concave?
This is a normal physical phenomenon and often occurs in products with
high water content. Carbon dioxide is a basic compound in air-conditioned
mixture. It is easy to dissolve water and fat in food to ensure that the
food has a lower temperature. That's why many products with CO2 in the
headspace produce a certain degree of vacuum inside them.
8. How do we know that the headspace volume and gas mixture ratio in
product packaging are correct?
Modified atmosphere packaging equipment has a special gas analyzer to
accomplish this task. These analyzers will give you fairly high-precision
information about the residual oxygen content of mixed gases in your
product. Establishing a good quality control system can avoid a large
number of product quality problems. Shandong Kangbeite Food Packaging
