Composition of Air
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

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.
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.
ADVANTAGE
Prevent growth of aerobic pathogens and spoilage organisms.
The KEEPIT oxygen absorber prevents the propagation of aerobic bacteria, such as mold, which cannot live without oxygen.
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.
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.
To eliminate insects and their eggs
-
The KEEPIT oxygen absorber eliminates pests It also works efficiently against eggs of pest

What is Aw(Water activity)?
A major consideration in choosing the right type of KEEPIT is to know how much a food product contains Water Activity (aw.)
Water activity is a measure of the amount of water available for microbial growth and other reactions in food.
It's expressed as a value between 0 and 1, with 1 representing pure water, with fresh foods having higher aw. values (0.98-1.00) and dry foods lower (0.20-0.60).
Molds have lower water activity limits, but molds generally involved in spoilage are at or above 0.7. There is no growth for any microbe below 0.6aw.
Most of these, particularly spoilage bacteria, grow at above 0.86 aw.
