I had not heard that appleseeds had arsenic in them until a viewer asked about it on our how to make applesauce video.
With a little searching, I found the Department of Energy Ask a Scientist site, where this question of arsenic in appleseeds was answered to my satisfaction.
Question – Do apple seeds have arsenic in them? Is it dangerous to
process apples with the seeds still in the fruit?
The good news: apple seeds do not contain arsenic. The bad news: apple
seeds DO contain cyanide. As for processing the apples, what kind of
processing are you interested in? Grinding apples and pressing them for
cider doesn't release enough cyanide to be a problem; neither does cooking
apples and straining them to make a sauce. About the only way you can
actually ruin into a problem with the toxicity of apple seeds is if you save
the seeds from about a bushel of apples and eat them all at once.
So, as long as you don't eat a bushel of apple seeds, you are fine. Eating a bushel full of anything could probably kill you, don't you think?
