About 3 yrs ago I bought and ground several .lbs of flax seed. I haven't used much since. I still got a bag full of it. Is it okay to use or should it be tossed?
It seems a year is how long it stays fresh whole. Once ground it should be refrigerated in an airtight container-and then it's good a few weeks. Exposure to air and light rapidly reduces its benefits. So you might want to toss it if its ground, or if you eat it maybe you'll be tossing
I'd toss it
I would toss it as well.
But I never buy ground or whole flax seed unless it's refrigerated. It's not bad for it to be in room-temp for a few hours (ground) to a few days (whole) but it goes bad very quickly in either case.
I've seen plenty of health food stores who keep their ground flax unrefrigerated, what a waste/ripoff.
