Oxygen Absorber Introduction
Oxygen absorber(also called Antistaling Agent, or Acid element Agent), keep the container in
anoxicstate condition by absorbing oxygen inside the package, it can effectively prevent the
growth of mildew and aerobic bacteria, to avoid goods becoming mildew, oil oxidation,
worm-eaten, aging, discolor and corrosion, thus to extend their shelf life. At the same time, it
also has a good effect in avoiding oily rancidity, meat oxidative browning and Vitamin losing.
1.1 Main Ingredient:
Iron power, activated carbon, diatomite, vermiculite, sodium chloride, water.
1.2 Technology:
Oxygen absorber is not food additives, it absorbs oxygen inside package by principle of iron
oxide, reduce the oxygen content to 0.01% in 0.5 to 2 working days, to protect the goods from
oxidative deterioration.
1.3 What Are Oxygen Absorbers?
Oxygen absorbers are devices that as the name suggests, absorb residual oxygen in a plastic bag
or container that is impermeable to oxygen. Oxygen absorbers are made of a chemical
compound, the active ingredient of which is a powdered iron oxide. Our absorbers are
completely safe. While they are not edible, they are not toxic. No harmful gases are created and
the oxygen does not remove the fresh smell and taste of the product. When used with proper
packaging and sealing, the oxygen in the packaging is greatly reduced.
1.4 What Are The Benefits Of Using Them?
Significantly improves keeping qualities of polyunsaturated fats and oils
Helps retain fresh-roasted flavor of coffee and nuts
Prevents oxidation of spice oleoresins present in spices themselves and in seasoned
foods
Prevents oxidation of vitamins A, C and E

Extends life of pharmaceuticals
Inhibits mold in natural cheeses and other fermented dairy products
Delays non-enzymatic browning of fruits and some vegetables
Inhibits oxidation and condensation of red pigment of most berries and sauces
1.5 What Are the Application Of Oxygen Absorbers?
1) Pastry: Moon cake, west cake, waffle, Swiss roll, mochi, green bean cake, rice cake, walnut
cookies, wife pie, light pastry, almond crisp etc.
2) Dried Meat: beef jerk, chicken wings, sausage, ham sausage, pork belly, dried
meat floss, dried salted duck etc.
3) Dried Nuts: pistachio, macadamia, almond, pine nut, pecans, walnut,
chestnut, peanut, seeds, peas etc.
4) Dried aquatic: abalone, fishes, scallop, squid, shrimp, grilled fillets, etc.
5) Local products: tea, nori, longan, litchi, mushroom, jujube, dried vegetables,
beans, persimmon, sweet potato, rice etc.
6) Medicals: Chinese herbal medicine, pharmaceuticals, health care product
7) Animal feed: fishing bait, pet food.
8) Others: precise instrument, military products, books, cultural relic, tobacco etc.
1.6 Precautions:
1. Put fresh food and oxygen absorber together into low oxygen permeability
containers
Eg: Oxygen permeability less than 20ml/m2.24h.25℃ package materia such as ,
KOP/PE; KPET/PE; Composite film bags or plastic containers, glass jars and
Cans etc;
2. Stock in sealed container, vacuum packaging.
3. It is better to used out within 1-2 hours once opened, the rest, resealed in time.
4. Do not microwave, do not eat, not suitable for high moisture content products.
5. Suitable working temperature 5—40℃, don’t suggest lower than -5℃.

1.7 How to Use an Oxygen Absorber?
Using an oxygen absorber is relatively easy. Make sure you are aware of all the procedures and
characteristics of storage, sizing, containers, handling. It’s economical and safe to use oxygen
absorber that offer an option to creating an oxygen-free environment that helps to improve
shelf life.
Simply put your food in a high gas barrier film package, metal can, or glass bottle; put the
appropriate size absorber in the container; and seal the container properly.
Points to consider:
Depending on the size of absorber used it will take 1 to 4 days to have produced an oxygen
free atmosphere.
Absorbers are packed in master high barrier bags of various quantities depending on their
size. Check the tightness of the vacuum packed master bag. If you hang the master bag
from one end, the packets should not be slip. If they do, do not use that master bag.
After opening the master bag, spread out the needed quantity of packets. The sachets that
are not used should be resealed in a master bag or discarded if their exposure to air
exceeds 4 hours(it is advisable to keep absorbers exposed to the air no longer than 1-2
hours.)
Remaining sachets should be resealed in the master bag, or another high barrier film pouch
or container, after pressing out the are. A well sealed proper size glass container will work.
Do not pile up absorbers in the tray or holding container. This may cause excessive heat
build up.
Do not remove and use and an absorber one by one leaving the master bag open.

Handle master bags properly and store in a cool (below 85 degrees[F]) and dark place.
Do not use zip-lock plastic bags or other flimsy containers to store unused absorbers.
Ideally, if you obtain your absorbers while relatively fresh, use them no later than 6 to 12
months after receipt.
1.8 Measurement of The Oxygen Absorber Volume in Your Container
In order to determine the correct size, you’ll need to know the volume of oxygen in your
container. The amount of oxygen that can be absorbed is indicated(in cubic centimeter(CC),
milliliters(ml) is equal to CC) by the size.(Example: 50CC will absorb nominal three times oxygen,
that means 50CC oxygen absorb capacity: 3×50=150CC )
Oxygen in container(ml)=(Air volume in container(ml)-Weight of product(g)/Specific gravity)
×0.21)
Example: Container size: 15×10×12cm, weight of product: 600g, specific gravity: 1g/ml
Oxygen in container=[(15×10×12)-600/1]×0.21=252ml
As Chunwang Absorber absorb nominal three times of oxygen, then absorber size=oxygen in
container/3=252/3=84ml.
Consequently, choose slightly larger and closest size 100CC.
