Like the illusion of Wall Street, with its vast and powerful investment banks, now shuttered, China too is an illusion perpetuated by the Globalists that gave us the 15,000 mile Caesar salad, poisoned cat food and lead based paint on babies' pacifiers. Like the illusion that money would come from thin air to always push housing prices higher, China has spent a generation pursuing its illusion. Pursuing an unattainable dream to be like the West, while 6000 years of its carefully shepherded top soil blows into the sea.

I saw canned chickpeas for 58 cents in walmart the other day and I wanted to store like 100s of them. Just as I was reaching to the shelf, I thought let me ask this to PO forum. I think they add artificial preservatives and additives to the cans just to lengthen their expiration date.
On the other hand, I am reading posts in this forum from folks who store these cans in bulks and I wonder if they know about this preservatives and other possible additives in the cans.

And how about preservatives? Chemicals?
Most canned foods only use salt as a preservative. Canned food with low salt will be labeled "salt free." Salt free canned foods would really only be necessary if you're on a low sodium diet or living on nothing but canned food, which would not be a good idea anyway for an extended period, but should be fine for a healthy person for awhile (I would think a few months, actually, without any noticeable health effects). Most canned foods aren't salt free. If you're looking for lower salt foods, be careful of those labeled "low sodium" as they often have potassium in place of salt, which gives a weird metallic taste to the food. Just be sure to read the ingredient label of whatever you buy. _________________ "...powerdown so soft and fluffy you'll think you're living in a pillow." - jboogy

Metal cans are coated with a thin layer of (petroleum derived) plastic. This coating leaches phthalates into the food. These compounds have estrogenic effects. Leaching is worse with acidic vegetables such as canned tomatos, but is a concern with all canned goods. The longer the cans are stored the more leaching. Whether or not this is a significant health concern is an open question. It may well be. As usual, more research is needed.

@Darwinsdog
What you have failed to show is that BPA is dangerous to humans in the concentrations that humans are exposed to. You can kill a rat by exposure to toxic levels of darn near any chemical. See below for some real testing of that plastic liner in tin cans that you are so worried about. I wonder why you didn't find it on the internet like I did in about 5 minutes of looking.
Regarding enzymes
They are proteins. They catalyze chemical reactions. They are not alive or dead in any sense of the word.
Now, if you want to make the claim that there are benefits from eating fresh fruit and vegetables then I have no argument. The canning process does reduced the vitamin C content. But to say canned food is dangerous requires proof.
From a nutritional standpoint, fruits and vegetables are low in calories and fat, and are important dietary sources of vitamins (particularly vitamins A and C and folic acid), minerals (potassium, in particular) and fiber. They contain no cholesterol and can contribute substantially to fiber intake, a food component almost always low in American diets. Conventional wisdom has said fresh produce always is better than processed. Our findings in this (as well as our 1995) study show canned fruits and vegetables generally stack up very well against fresh. Although there is some loss of vitamin C content during heat processing, canning usually results in stable levels of most essential nutrients (. The amount of a vitamin or mineral or fiber in canned food remains the same, even after one to two years of storage. Detailed nutrient information about selected fruits and vegetables are given in the tables and the brief summaries that follow.
Furthermore the FDA has done studies on BPA(that plastic lining in cans) with contradict the studies you cited about.
Consumer exposure to BPA is extremely low
A person would have to consume more than 1,300 pounds of food and beverages in contact with polycarbonate plastic or more than 500 pounds of food and beverages from cans lined with epoxy resins, every day for a lifetime, to exceed the safe level of BPA set by the U.S. Environmental Protection Agency (EPA).
Quote:
The key studies on which experts, government officials and industry rely for the conclusion that there are no reproductive or developmental risks from exposure to BPA at levels anywhere near levels a consumer might encounter include:
* A continuous breeding study in mice, conducted by the U.S. government's National Toxicology Program, showed no effects on reproduction at a dose approximately 4000 times higher than the highest dose tested in the Current Biology study (Ref. 39).
* A study conducted at the Research Triangle Institute examined parents and three offspring generations of rats exposed to BPA. No evidence of developmental or reproductive effects was found at doses anywhere near levels to which consumers might be exposed (Ref. 54).
* A similar two-generation study sponsored by the Japanese Ministry of Health and Welfare found no developmental or reproductive effects at any dose tested. This study also included two behavioral tests of offspring, including a learning test, and found no effect of BPA at any dose (Ref. 12).
Genetic testing:
BPA has been studied using a standard internationally recognized test for determining genetic effects - the mouse micronucleus assay. No such effects were found, even at a dose 20,000 to 100,000 times higher than the doses tested in the Current Biology study (Ref. 5).
In summary, many of the studies that ordinarily might be conducted in response to the Current Biology findings had previously been conducted and do not indicate a reproductive, developmental or genetic risk.
Although the Agency’s review of the newly available reports is continuing, a large body of available evidence indicates that currently-marketed food contact materials containing BPA are safe, and that exposure to BPA from food contact materials, including exposures for infants and children, are below the levels that may cause health effects.
We are actively reviewing the data on BPA and will continue to consider the relevance of new data and studies as they appear. FDA’s work in assessing the safety of these products is never truly final, and if our continuing review of all available data leads us to a determination that the current levels of exposure to BPA are not safe, we will take appropriate action to protect the public health. Thank you for the opportunity to testify today, and I would be happy to answer any questions.

First of all I would neither buy or store canned chickpeas - they taste yuck! Why do you not buy the dried ones? They are lot cheaper, yummy, last for ages and you simply eat them and replace what you have eaten. They take much less storage space. I only store what we're eating normally.
I would not store any vegetables at all. First you can make some days / week without. Second garden cress spinach mustard ... grows n less than a month, you can even have a box of greens on a balcony (however it will be barely more than survival) , you can gather wild stuff. As vegetables are relatively easy to grow and you don't need lots of space it is likely that there will a supply.

Speaking of stocking up on canned goods-I read on another site that you should dip the ends of the cans in parafin for longer preservation. Anybody here do that? I have been looking for some parafin locally and not having alot of luck.

Unless your cans are subject to water condensing on them, leading to rust, dipping them in paraffin or wax is a waste of time. The contents are as sealed as they are going to get. The paraffin won't extend the usable shelf-life of the food inside.
If you are rotating these through the regular food that you eat(store what you eat) you shouldn't have any problems with rust either.

It was the rust issue they were addressing. I haven't had can goods potentially laying around for a long time until now. Our unfinished basement area stays very dry and we have the cans on shelves and/or cabinets. I don't have alot of experience with the "rust factor" and canned goods.

The only food worth canning is meat. Canned vegetables and even legumes is a waste of precious energy--because of the high water content. Why bother canning water? Look at the nutritional content of a can of beans--350 or so calories?? You don't need vegetables to survive--you need calories. Store calories in the most dense form--dried food. (only the 150th time I've said this)
