Food Irradiation
Food irradiation is the process of treating food with a specific dosage of ionizing radiation.[1] This treatment slows or halts spoilage by retarding enzymic action or destroying microorganisms and it can also inactivate food borne pathogenic organisms (reducing the risk of food borne illness). Further applications include sprout inhibition, delay of ripening, increase of juice yield, and improvement of re-hydration. Irradiation is also used to prevent the spread of invasive insect species that could be associated with fresh produce (e.g. fruit fly pests).

The Irradiation Process
A cart system moves the products to be irradiated under the electron
beam at a predetermined speed to obtain the desired dosage. Multiple
carts move products in and out of the irradiation area continuously
with throughput up to 500 pounds per hour. Maximum product
dimensions are 24 inches wide and 36 inches long. Product thickness
depends on density and electron energy. For example, 3.5 inches is the
maximum thickness for meat. Using X-rays increases thickness to
several feet for various products.
The Meat Laboratory
The meat laboratory, attached to the Linear Accelerator Facility, has
complete slaughter, cutting and processing operations with
refrigeration and frozen storage. An analytical laboratory may conduct
chemical, sensory, microbiological and physical analyses on the
irradiated product.
In addition to meat, the irradiation process can be conducted on a
wide variety of fresh vegetables, fruits, and spices, as well as some non-
food industrial products.

What is
Preservation
on
Packaging?
![Page 11: T.l.e food irradiation](https://reader031.fdocuments.us/reader031/viewer/2022013115/559428881a28abfb408b4615/html5/thumbnails/11.jpg)
Packaging helps to control the immediate
environment of a food product, it is useful in
creating conditions that extend the storage
life of a food. Plastic materials are widely used
in food packaging because they are relatively
cheap, lightweight, and easy to form into
desired shapes.
![Page 12: T.l.e food irradiation](https://reader031.fdocuments.us/reader031/viewer/2022013115/559428881a28abfb408b4615/html5/thumbnails/12.jpg)
Here are some tips in Safe Food packaging:
1.Packages from products other
than food should never be used
as food containers. They have
not been tested for safety with
food systems, and they may
contain small amounts of nonfood
residues. (For example, do not
use plastic laundry detergent
buckets for storing dry cereal.)
![Page 13: T.l.e food irradiation](https://reader031.fdocuments.us/reader031/viewer/2022013115/559428881a28abfb408b4615/html5/thumbnails/13.jpg)
2. Glass can be reused for all
foods and for all processes.
This is true regardless of what
food was originally packaged in
the glass container. There is an
exception to this rule: single-
use glass jars should not be
used for pressure processing
in the home canner.

3. Do not reuse porous packaging
materials such as
paper, paperboard, and expanded
foams (for example, styrofoam
cups and foam meat trays). They
have air spaces that will harbor
food particles and
microorganisms.

Steps In Packaging Food
in
Vacuum Pack Food With
an Automatic Machine
![Page 16: T.l.e food irradiation](https://reader031.fdocuments.us/reader031/viewer/2022013115/559428881a28abfb408b4615/html5/thumbnails/16.jpg)
1. Clean and prepare the food that you wish to vacuum pack.
![Page 17: T.l.e food irradiation](https://reader031.fdocuments.us/reader031/viewer/2022013115/559428881a28abfb408b4615/html5/thumbnails/17.jpg)
2. Place the food
inside the plastic
bag. Most machines
require using a
specific brand of bag.
![Page 18: T.l.e food irradiation](https://reader031.fdocuments.us/reader031/viewer/2022013115/559428881a28abfb408b4615/html5/thumbnails/18.jpg)
3. Put the open edge of
the bag into the sealing
machine.

4. Press the
button, if
necessary, to
start the
vacuum and
sealing process.

5. Watch as the
vacuum pack food
machine withdraws
the air and the plastic
bag shrinks.

6. Wait for the
machine to stop its
operation, which
signaling that the
plastic bag has
properly been sealed.

7. Remove the
vacuum packed
food and store it in
the pantry, fridge
or freezer.
