FOOD SAFETY
Vacuum-packaging
When vacuum-packaging food in vacuum-storage boxes, most of the surrounding air is extracted whilst
the inflow of fresh air is being prevented. This way the storage life of food is lengthened.
Vacuum-packaging helps to prevent freezer burn, which is the dehydration of the surface layer of the
food. This is characterised by white or brown-red discolouration of the food.
Vacuum-packaging contributes to the preservation of the taste and the overall quality of the food. It
slows the growth of aerobic micro-organisms that could cause:
Mould. As mould won’t grow in environments with little oxygen, the vacuum-packaging will
strongly reduce the risk of moulding.
Fermentation. Fermentation can be noticed by the odour or taste of the food. Fermentation
requires water and sugar and will develop at room temperature. Fermentation can also develop
when air is lacking. In order to slow the yeast growth items should be cooled, only at deep-freezing
temperature, this growth will come to a halt.
Bacteria. Bacterial growth can often be recognised by a nasty smell, discolouration and a soft or
slimy layer. Under specific circumstances, clostridium botulinum, which causes botulism, can grow
without air. This is rare, but also extremely dangerous. You can neither smell nor taste it.
The vacuum-packaging is no replacement for cooling or deep-freezing. Perishable foods that require
cooling or freezing, must still be kept in the refrigerator or freezer.
Deep-freezing
In order to safely preserve foods, it must be kept at low temperatures. The growth of micro-organisms
is strongly reduced at temperatures of 4°C and below. At a temperature of -17°C, growth will nearly
come to a full stop. This does however not kill the micro-organisms.
If you wish to store your vacuum packed food long-term, then always place it in the freezer.
Verify
Always check if food is spoiled, before consuming it. You must realise that vacuum-packaging cannot
undo spoilage. Vacuum-packaging only ensures that the quality of food is retained longer. How much
longer you can preserve the food, depends on different factors, such as the quality of the food at the
time of packaging. We advise to only package fresh food and mention the date of packaging on the
package.

PREPARATIONS
Before you can start vacuum-packaging vegetables, they need blanching. This will inhibit the enzymatic
activity which causes loss of flavour and colour fading. Cook the vegetables or place them in the
microwave until they are done, but still a bit crispy. Subsequently you immerse the vegetables in cold
water, stopping the cooking process. Next, dry the vegetables with, for instance, a clean towel.
Cruciferous vegetables, such as broccoli, sprouts, cabbage, cauliflower, kale and turnips produce
carbon dioxide during preservation. Therefore, you can only store these vegetables in the freezer.

USING THE VACUUM DEVICE
Unpacking the vacuum device and preparations for first use
Take the vacuum device out of the box and remove all packaging materials. Place the vacuum device
on a horizontal surface in a location where the vacuum device cannot tip over, even when passing.
Switching on the vacuum device
Insert the plug of the vacuum device into a wall socket. The vacuum device is now ready for use.
Seal and vacuum a product in a vacuum bag
Choose a vacuum bag of suitable width and place your product in the bag, leaving approximately 4 cm
open at the top. Open the lid of the vacuum device and place the open end of the bag over the sealing
strip with the open end inside the vacuum chamber.
Close the lid and press it lightly whilst shortly pressing the vacuum button. The vacuum indicator will
light up. After approximately 3 seconds you may let go of the lid; it will stay in its closed position. The
vacuum bag shrinks whilst the inner air is being removed; after a while the vacuum indicator goes out
and the seal indicator lights up. Wait until the seal indicator goes out.
Now press the release button, open the lid and take your vacuum bag out. Carefully inspect the seal.
A proper sealing will be transparent over the entire length. If the sealing is mottled, white or milky or
even crumpled, then it is not properly sealed. In this case, cut off the sealing and create a new sealing
in accordance with the abovementioned steps.
Wait at least 45 seconds before you vacuum or seal a second bag.
Seal a product in a bag (without a vacuum)
Choose a bag of suitable width and place your product in the bag. Open the lid of the vacuum device
and place the open end of the bag over the sealing strip, but not into the vacuum chamber!
Close the lid and press it lightly whilst shortly pressing the seal button. The seal indicator will light up.
After approximately 3 seconds you may let go of the lid; it will stay in its closed position. Wait until the
seal indicator goes out.
Now press the release button, open the lid and take your vacuum bag out. Carefully inspect the seal.
A proper sealing will be transparent over the entire length. If the sealing is mottled, white or milky or
even crumpled, then it is not properly sealed. In this case, cut off the sealing and create a new sealing
in accordance with the abovementioned steps.
Wait at least 45 seconds before you seal a second bag.

Tips for packaging
Pack the food as freshly as possible. By means of vacuum-packaging, the freshness of the food can be
retained up to five times longer, compared with food that is stored under regular circumstances.
Delicate and moist food, as well as food of which the shape should be retained, must first be frozen.
Food such as meat, berries and bread can be frozen up to 24 hours before freezer burn starts. As soon
as the food is solid, you can deep-freeze it.
If you choose to package meat without freezing it first, then place a folded paper towel between the
meat and the top of the bag. This will absorb moisture.
Firstly, freeze liquid food, such as soups, stews and casseroles in, for instance, an oven dish. As soon
as they are frozen, they are ready for vacuum-packaging, marking and storage in the freezer.
Cover sharp points and edges of products such as bones, pasta and rice first, using a paper towel. This
reduces the risk of the vacuum bag being punctured.
Vacuum bags are suitable for the microwave and are hot water resistant. You can re-use vacuum bags,
unless they have been used to store fish or fat food. We recommend that you do not re-use vacuum
bags that have been cooked or been in the microwave.
Vegetables should be blanched first before vacuum-packaging is done. Mushrooms and garlic cannot
be vacuum-packed.

AFTER USE
Cleaning
Allow the sealing strip to cool off first before cleaning it and remove the plug from the socket. Clean
the outside of the vacuum device with a damp microfiber cloth and soft soap. Remove all moisture
from the vacuum chamber and keep the sealing strip free from dust and dirt.
Storing
After the sealing strip has been made dust and dirt-free and the vacuum chamber is dry, you can store
the vacuum device.
Maintenance
For an optimal lifespan of your vacuum device, we recommend a waiting time of at least 45 seconds
between sealings.

RECYCLING THE VACUUM DEVICE
If the vacuum device is at the end of its life cycle, you can deliver it to a collection point for the recycling
of electrical equipment. The vacuum device should not be disposed of along with regular household
rubbish.

APPENDIX: STORING ADVICE FOR FOODS
The vacuum device will change the way you purchase and store foods. As vacuum-packaging
decelerates spoilage and prevents freezer burn, you can buy more foods at a time without the risk of
waste.
Using the vacuum device, you remove up to 90% of the air from the packaging. As such, foods can be
kept up to five times longer than when storing it the normal way. Dry foodstuffs such as pasta, grains
and flour will even stay fresh from the start to when being used. Also, using vacuum packaging you
prevent beetles and insects from nestling in your foodstuffs. Package foodstuffs always as freshly as
possible.
Please note: Not all foods are suitable for vacuum packaging. You can never vacuum pack garlic or
fungi such as mushrooms. Removing the air could initiate a biochemical reaction, making consumption
of these products very dangerous. Vegetables should first be blanched to break down the enzymes
that produce decomposition gases.

APPENDIX: OTHER VACUUM-PACKAGING APPLICATIONS
You can also use the vacuum device for domestic applications other than food packaging.
Vacuum-packaging is quite suitable for camping and outdoor activities
Reusable cooling packs you can make yourself, by half filling a vacuum bag with water to which a few
spoons of methylated spirit were added. Seal the vacuum bag, without vacuumising, and place it in the
freezer. The methylated spirit prevents the water from freezing entirely. You can use the vacuum bag
for treatment of aching joints and small injuries.
You can prepare vacuum-packed meals before you go camping. This way it is easy to prepare meals
while camping.
Vacuum packaging of meat and other smelly products prevents undesired odours.
Make your own dry packs by keeping essential items, such as matches, socks and a map in a sealed
bag.
Domestic applications
Reorganise untidy cabinet drawers by vacuum-packaging small stuff that might otherwise be lost, such
as screws and nails, into vacuum bags. The content of the bags will remain easily visible due to the
vacuumising.
Hardly used silverware can also be vacuumised. This will prevent discolouration of the silver as a result
of oxidation. Sharp corners can be packed by use of a paper towel, preventing the vacuum bag from
being punctured.

SYMPTOM
POSSIBLE CAUSE
SOLUTION
The vacuum device does not
work if you press one of the two
buttons.
The power cord is damaged, the
plug is not in the socket or there is
no voltage on the socket.
First check if the power cord is
undamaged and then insert the
plug into a socket which you know
has power.
The status indicator flashes
and/or you hear a beep tone.
You press on the “vacuum seal” or
the “vacuum only” button while
there was already a vacuum.
Unlock the lid. This will remove
the vacuum in the vacuum
chamber.
The vacuum device does not
completely vacuumise the
vacuum bag.
The top of the vacuum bag is not
entirely into the vacuum chamber
(over the sealing strip).
Place the opening of the vacuum
bag entirely in the vacuum
chamber.
There are wrinkles in the vacuum
bag in the part that is on the
sealing strip.
Check the top side for wrinkles,
and, if necessary cut off the top
edge of the vacuum bag.
You have made a vacuum bag of a
vacuum roll and the first sealing is
not correct.
Check the first sealing for
damage. Cut off the damaged
sealing and make a new sealing.
The vacuum bag is losing its
vacuum after it was sealed.
Sharp objects could puncture the
vacuum bag.
Cover any sharp edges using a
paper towel and use a new
vacuum bag.
Certain vegetables and fruit that
were not properly blanched or
were frozen prior to packaging,
may cause decomposition gases.
Open the packaging and throw
away the foods in case they are
spoiled. If the foods are not
spoiled, they must be eaten
straight away.
The vacuum device does not
properly seal a bag.
The sealing strip of the vacuum
bag is wet, dirty or dusty.
Remove the plug and clean the
sealing strip. Use only clean, dry
vacuum bags.
The bag is not placed over the
sealing wire.
Check that the bag is properly
placed over the seal wire.
The open end of the bag is inside
the vacuum chamber.
Place the open end of the bag just
over the sealing wire. For sealing
without vacuum the open end of
the bag should not be inside the
vacuum chamber.
The vacuum device no longer
works (properly).
There is a technical failure
malfunction.
Remove the plug from the socket,
wait 10 seconds and reconnect
the vacuum device.
