Silica gel desiccant are utilized like a desiccant in a number of food items and in many other purposes in which the conditions is required to be totally free of moisture. The desiccant operates by removing unwanted moisture from the air in an enclosed surroundings. Desiccant packets are used for storage for foodstuff, for example for beef jerky.

Silica gel packets may also be employed for other applications too. An excellent example would be the dehydrating involving organic and natural materials, such as fresh picked organic mushrooms. Fresh organic food like fresh mushrooms need to be dehydrated to stop the mushrooms from decaying or spoiling when in storage. Dehydrating all these organically grown products by using a desiccant prevents spoilage because the fungi or bacteria that trigger spoilage require water to thrive. With no moisture the decomposition of such an organic substance is slowed down tremendously. This is really practical when there is no an industrial dehydrating equipment accessible.

By using a silica gel packet like a desiccant you are able to save food items that would go bad under normal moisture circumstances forever.
