Oxygen Absorber

Keep your foods fresh during transit or storage.
Reduce wastage and cost saving



​​Oxygen makes up approximately 21% of the air in the atmosphere and it is crucial to all creatures. However it can also support the growth of fungi and micro organisms which can made the food unfit to eat

Oxidative rancidity


Oxidative rancidity, one of the major causes of quality deterioration in foods and to prevent food rancidity is to eliminate oxygen

Food that is exposed to oxygen will have faster rates of going rancid. So, if you want to extend the shelf life of food you need to remove the oxygen

Food preservatives allow us to keep food safe keep longer. Preservatives might inhibit oil from going rancid and retain its original color

KEEPIT - Oxygen Absorber



KEEPIT - Oxygen Absorber (iron type) is a specially treated iron powder. When iron rusts, it absorbs oxygen in the process. The result is de-oxygenation of the sealed container or airtight package. They are non-toxic and safe to use.

This process begins once the oxygen absorber packet is exposed, the iron fillings start to oxidize straightaway, which forms rust and starts releasing nitrogen, it helps in keeping food fresher for a more extended period.

​With relatively strong capacity of oxygen absorption, it keeps freshness on a wide variety of food products. By removing oxygen and create a O2 & CO2-free environment in a sealed package, it will keep the freshness, original taste and color of foodstuff, and prevent it from staling, oxidative rancidity, growth of mold, aerobic and anaerobic microorganisms

To keep the food safe and fresh for long term storage, you'll need to remove virtually all the oxygen and make sure you use enough oxygen absorber.

Below is a general guideline of how many oxygen absorber you will need

General formula

Container volume - food volume = Residual air volume
Note: 1 gram - 1 cc

Use with right packing material

Oxygen absorber does its job when they are used in high quality packaging. Please ensure you are using packing material with a high oxygen barrier.

Seal the package perfectly with a professional machine.

In order to maintain an oxygen free condition for a certain period of time, select packing material with a high resistance to oxygen permeability. KEEPIT pack use materials with a high oxygen barrier such as plastics, trays, metal cans and glass bottles.


Choose the type of product that meet your demand

Choose the type of our oxygen absorbers that suits your product such as the volume of your container and characteristics of your product.

Placing the oxygen absorber properly

An incorrect placing of oxygen absorber will make it useless,for example, you should place the oxygen soborber under the blister paper of an individual mooncake packge  instead of direct contacting with food.

What Are The Benefits Of Using Oxygen Absorbers?


Extends shelf life

Oxygen absorbers absorb oxygen and effectively reduce the aerobic environment to almost 0% oxygen. Therefore aerobic bacteria and fungi are unable to grow in this environment. This will extend the shelf life of a food product drastically.

Oxygen-free packaging allows you to eliminate both adult insects and their eggs

The KEEPIT oxygen absorber eliminates pests but is safe to humans because it is not a toxic insecticide. It also works efficiently against eggs of pest

prevent growth of aerobic pathogens and spoilage organisms, including molds

The KEEPIT oxygen absorber prevents the propagation of aerobic bacteria, such as mold, which cannot live without oxygen. KEEPIT can absorb the small amount of oxygen which comes through the package film and can thus keep foods from getting moldy for a very long time.

To help retain fresh-roasted flavor of coffee and nuts

Oxidization has an adverse effect on color and taste. KEEPIT prevents changes of pigment in foods and at the same time protects aromatic elements in foods such as coffee, tea and seaweed, keeping them tasty and fresh.

Prevention of oxidization of fat, vitamins etc

When fat contained in foods is in contact with oxygen, it oxidizes and deteriorates. In the case of vitamins E and C in foods, this causes depletion in the strength of the vitamin or change in its quality. KEEPIT stops oxidization and maintain the quality of the food by protecting nutrients from deterioration.

To eliminate the need for additives such as BHA, BHT, sulfur dioxide, sorbates, benzoates, etc
