Where? I read the entire thread and I do not see were these questions are answered. I bought 20lbs of rice in a plastic bag with a zip lock top thinking that would be better than the other porous type bags they had. Would packaging in jars prolong the storage life?
Also, are the oxygen absorbers from MREDepot individually packaged so you can use one at a time or do you expose the entire lot when opened?
New to this, so please excuse me!
I apologize to you Donnie740 and thank you LukeNM for challenging my perhaps hasty response. The answers may not be as clear as I thought after all. I've assumed some basic background information that you may not be aware of, especially if you are new to the forum. My bad.
1) Why is it that one would want to store beans/peas etc in mason jars rather than just leaving them in the bags they're bought in?
Partially answered in post 28. Post 6, among others, reveals that the subject is long term storage of foods, a very frequent topic of discussion in the Survival Prep section of the forum. The discussion of oxygen absorbers and vacuum is pertinent because oxygen causes foods to "oxidize" and spoil over time. The shelf-life of foods can be greatly increased by removing oxygen from your food packages. Whereas beans or pasta may remain relatively fresh, nutritious, and palatable for a year or two in the original oxygen-filled plastic bag they were purchased in, they can last 10 to 30 years in a dry, cool, oxygen-free environment. You usually cannot achieve that kind of environment in the original food package. Sealing foods with oxygen absorbers in heat-sealed mylar bags, often in sealed buckets, is one way that people commonly pack dry foods for long term storage. This mason jar method allows you to store smaller quantities.
2) Is it to protect against water/vermin damage or does it keep them fresher for longer periods?
Both. Heat, moisture, and oxygen are the main promoters of food decay. Time too, in the long run. There's a limit to how long you can keep food, even in the best environment you can manage. Vermin will also destroy your food if they can get to it. Glass is even better than mylar bags and plastic buckets when it comes to vermin protection and oxygen permeability. A downside is that glass is also more susceptible to breakage, and is a heavy and bulky form of packaging compared to 5 or 6 gallon mylar bag/plastic pails.
3) Also, how important is it the jars be vacuum sealed?
Post 72. It's debatable whether the additional vacuum obtained by the FoodSaver is superior to using oxygen absorbers alone, but it seems like it couldn't hurt to do it, and it probably results in a greater vacuum inside the jar, which may at least hold the lid on more tightly. We'll have to wait many years, up to 30 maybe, to find out if it is really better.
