Iron in dried apricots?

[OakLeaf]

If you compare calorie for calorie dried vs. fresh vs. dehydrated, there's obviously something else going on besides taking out the water weight, but I have a feeling it's one of the things I guessed at.

Raw apricots have .008 mg Fe/kcal; sulfured dried apricots .011; sulfured dehydrated apricots .019. That's a lot of variation.

Anybody have any idea how big a sample size the USDA uses to come up with those values?

IAE, obviously food is NOT fungible, so there's no guarantee the apricots each of us eats have the same amount of iron as the ones the USDA sampled. Guidelines only ... not rigid values for counting ...
