I know that once you grind flaxseeds you are supposed to refrigerate them. Yet I often see preground seeds(such as Bob's Red Mill) in stores and they are never refrigerated. Do they lose all of their benefits when they are packaged this way?<img alt="" class="inlineimg" src="/images/smilies/huh.gif" style="border:0px solid;" title=":confused:"> Karen

Yes they loose part of their benefits as the omega-3 and other essential fatty acids oxidize (go rancid).

They should be okay as long as the package is not opened. Once it's opened you'll want to store it in the freezer. The store really should be keeping them in a refridgerated section, but I'm not sure how critical it is for the unopened containers. It's better though to get the whole seeds and grind them yourself if you're able to, and then keep them in the freezer until you're ready to use them.

I have also heard that anything with omega -3's should be kept in a cool, dark place. I like to buy the pre-milled seeds that are refridgerated and kept in a bag that is dark/foil so the light doesn't damage the unstable fatty acid chains.

You should smell any grain with a germ, like brown rice for rancidity before using. Grains like brown rice and things like fatty nuts (walnuts) should be stored in a cool dry place (a freezer or refrigerator is good too). You should always check anything made with fats or oils-- including nut butters, margerines, or any cooking oils for a rancid oder. Oils are unstable. The less fatty acid chains the more unstable the oil. Rancid means that electrons have escaped & the oil has oxidised. The lighter the oil, the less electrons and less ability to hang onto the electrons. (Saturated fat is actually the most stable fat). Many light fats like mono- and poly unsaturated should not be heated (or you should check the lable for tempreture it is safe to heat it to-- some can take higher temps). Walnut oil is fragile and should not be heated at all. Olive oil can be heated to a fairly high temprature. (I mention the heating part because oils also loose electrons when you heat them and become just as dangerous as when they are rancid). What the electron becomes when it escapes is a free radical. What the leftover oil or grain becomes is a free radical magnet. Don't eat it, and dont throw it down the drain to be consumed by wildlife or other people. --Oh to stabalize an oil, I've been told to drop a tab of dry vitamin e (an anti-oxident) in it. It is also better to store it in a brown light proof container. Also, buy oil in the smallest container possible and make sure it is fresh. You should not keep it any more than a few months-- Use it on your hair (if it is not rancid already) if you need to use it up, but dont eat it.

This getting rancid is the reason why to many white stuff like rice or flour is sold - it has a longer shelf life!
