Oxygen is the reason for the sustenance of life
on earth. But its presence at irrelevant places can often prove to be fetal.
So, in order to remove oxygen from unnecessary places, oxygen scavengers or
oxygen absorbers are used. With the revolution of these oxygen absorbers the
life of the products has increased, especially in case of stored food material.
Now, food can be stored for a longer period of time. Oxygen absorbers are
basically small packets of iron powder. These packets are made up of such a material
which allows oxygen and moisture to enter but powdered iron cannot leak out.
The iron powder absorbs moisture and traps it inside. As these packets are not
toxic it is absolutely safe to place it on the top of the food item. They will
not cause any harm to the food item as the powder is safely packed inside the
packet.
With animals and humans it is the key for the
survival of micro-organisms as well. These organisms are fetal, if they found
any way for growth in the edible items. So, by stopping oxygen to enter any
food item it becomes easy to stop the growth of microorganism. The effect of
growth of these microbes can be easily seen on the food items as food item
immediately starts to lose its originality. Smell, taste and texture starts to
change. Not only in edible but in non-edible items as well we can see the
change. For example, metal if left unpolished its direct contact with oxygen
will corrode the metal.
