All About Oxygen Absorber Sachet - O Sorb

What are Oxygen Absorbers?

O-sorb, also known as Oxygen Scavenger or Oxygen Absorbent, is an Oxygen Absorber made from a safe, non-toxic material that can help prolong the shelf life of food products. The O-sorb is manufactured from Japanese technology and materials. The four-layer laminated packing allows active oxygen absorption, preventing its active powder from directly contacting food.

The O-sorb absorbs oxygen entirely in the package and significantly extends the best-before date of packaged food or other products by the oxidising reaction of Iron Powder. It prevents mould growth, discolouration, and oil oxidation and helps to preserve the fragrance and flavour.

Oxygen Absorbers, as mentioned above, are packages of iron powder that absorb oxygen in packaging applications. When O-sorb Oxygen Absorbers are placed in an airtight container, the oxygen is absorbed by the iron in the oxygen absorber, leaving only nitrogen in the air (does not affect food).

Different Types of Oxygen Absorbers & How to Use Them

The O-Sorb is available in many sizes in the market to cater to various needs. The sizes are counted based on the product size and whether the product is wet or dry. The amount of oxygen present depends on the volume of the empty spaces in the package. For instance, if the volume of space is 100ml, there will be 20ml of oxygen present as air is made of 20% oxygen.

The O-sorb Oxygen Absorbers available at Humi Pak come in different sizes, ranging from 10cc to 3000cc, to ensure they can support all market needs and wants. Some sizes available are U Series or K Series (U-20, U-30, U-50 & U-100), which are more common requirements in the market. The number in the product’s name indicates the capacity of oxygen the O-sorb can absorb. For example, a packet of U-20 will be ideal if there is 20ml of oxygen present in the package.
