When it is related to survival food storage plans of yours, it is inedible, tiny little packet that can make entire difference. Basically, oxygen absorbers are efficient, cheap, and useful methods for preserving wide range of foods with minimum added scent or any other negative results thereby making them vital aspect of all good preppers stockpile. Let us have a glance at how exactly these little chemical miracles can protect your food!
Why in the first place do we need to drain away oxygen? Prior to discussing how oxygen absorber works, we should point out harm that oxygen will do to your food: for instance, wheat requires oxygen absorber for preventing mould, discolouration, and rancidification. Oxygen leads to rancidity in several common foods like spices, meats, grains, and nuts. Oxygen encourages fats, oils, as well as other chemical compounds in foods for ruining, spoiling them as well as leading to that terrible smell that commonly we associate with those rotted foods.
It leads to reduction in moulds that grow on specific foods. Though pretty few moulds will be anaerobic (can survive even without oxygen) maximum need some oxygen at least for growing. Truly oxygen absorbers can’t remove all oxygen (at one point there would be pretty small quantity of oxygen that’s extremely small for reacting with packet) but they have the ability to remove majority that several moulds require for growing. It reduces odds that those poisonous moulds would be ruining your stocks.
Oxidized foods or discoloured foods lead to odd tastes. Oxygen will react in varying ways without food of ours, common one is both to ruining and discolouring food by turning it terrible in taste even when they still are technically healthy for eating (though I don’t suggest it owning to risk of those invisible mould spores!). If oxygen is removed your food will look fresh as well as taste better and this is pretty important while one is already in stressful survival situation!
Even oxygen can oxidise vitamins within the food! Vitamins oxidation will result in several issues but one of the major concerns for prepper is loss of nutritional values. Food that is freshly packed effectively in oxygen-rich environment would lose nutritional value of it to some extent because oxygen will break down vitamins themselves. Vitamins E, A, and C are known commonly to react with oxygen as that is one of the major purposes as soon as they reach your body. Having these factors in mind it is pretty clear that several foods would benefit from oxygen-poor environment.
Enter oxygen absorber!
How can tiny scavenging packet of oxygen drain entire oxygen can? Key to average oxygen absorbing packet (like these) is chemical reaction that is between sodium/iron in packet in addition to moisture in surrounding air. Plastic allows moisture through as well as combination of sodium and wetness leads to iron in packet to get rusted thereby forming iron oxide.
When this oxidation takes place, rapidly packet drains all of that oxygen out of sealed container (though more effective or larger packet is designed for containing metal rust and shaving hence oxygen gets removed but food will be left untouched. Remaining elements in air (argon and nitrogen mainly, though there are other trace elements always there) generally don’t react with food meaning one can extend shelf life simply on survival foods by removing oxygen.
Extra means of improving effectiveness of oxygen absorber- at first ensure that you are using absorber that is rated properly for size of container as well as the kind of food that you will be using. Denser food (like powder) leaving fewer holes in can for hiding oxygen use small absorber even in same sized cans hence daily consider both density and size. Generally speaking, metal and glass containers (canning jars, #10 cans, and mason jars) are much effective when compared to modern plastics as plastic still permits oxygen to penetrate based on quality of plastic that is in question.
The lesser that oxygen continues filtering in once absorber has finished its work, the better it would be. Lastly, minimize time that oxygen absorber invests in outside world prior to it going into sealed container. More time that it invests in absorbing oxygen from open air, less effective would it be when it is concerning absorbing much restricted amount inside container.
When absorber becomes warm or feels as if it is much more solid when compared to powdery, it already has utilised maximum of its potency. In general, oxygen absorbers will be great for keeping food healthy, nutritious, and free from the rot. Ensure you are including some of it in foods that are benefited from oxygen less environment.
