Oxygen elimination by use of porous absorbers

Oxygen is needed by all living beings as it is the one component of air that carries out the process of respiration. However it can be a damaging component to several food stuffs and metals where it forms free radicals that react to produce harmful compounds. Oxygen can be removed from the vicinity of food stuffs and other materials by placing oxygen absorbers with them. There are several desiccants available in the markets that keep harmful oxygen at bay. These are available in the form of packs and stripes. By usage of these materials, putrefaction of food stuffs can be checked and preservation is achieved without use of expensive methods like gas flushing and vacuum sealing. In this way, manufacturers can save millions of dollars worth food stuff that would otherwise require costly preservation that often involves preservatives and expensive treatment.

Oxygen Absorbers for Pharmaceutical Packaging

Oxygen Absorbers are a handy way of increasing shelf-life of packaged food & pharmaceutical products. As the name suggests an "Oxygen Absorber" work on the principle of removing oxygen gas from controlled packaging environment. Lowered levels of oxygen directly improve the shelf-life of packaged food products stored at room temperature.  In pharmaceutical, nutraceutical and other packaged drug industry, lowered levels of oxygen means drugs that are normally prone to oxidative degradation will remain stable for a long period of time.

Oxygen Absorbers

Oxygen absorber packets employs chemical reaction between ferrous powder and oxygen gas to create ferric oxide. A strong affinity for oxygen, and low reactivity to other gasses, makes elemental Iron most suitable for such application. By this means oxygen gas can indefinitely be reduce to relatively low levels in packaged goods. The Ferric powder and other constitutes like salts and chelates that support the reduction process are encased in a poly pouch which allows for gas exchange to take place. Such pouch has capacity to remove oxygen, throughout the shelf-life of the packaged product, as long as, there is ferrous powder readily available for oxidation.

Oxygen Absorbers for Food Packaging

Oxygen Absorbers

Sorbead India is supplier of oxygen absorbers can extend the shelf-life of food product making them perfectly viable for local chain distribution or global bulk export. A prime example is export market of Cashew nuts. Rancidity and fungal growth are 2 factors that retard the shelf-life of cashews and inturn, decrease the market for export for cashews.

Rancidity or taste change in cashews develops due to the chemical decomposition of naturally occurring fatty acids & lipids. In the presence of atmospheric oxygen fatty acids & lipids degrade giving up undesirable odors & flavors. Fungal growth is as detrimental to these nuts as rancidity. In some cases, fungi can induce rancidity by organically breaking down th

e fatty matter. Oxygen Absorbers can serve to actively protect both of these limiting parameters.
