Is this Sweet Potato safe to eat? [pic]

I purchased this at the Asian supermarket. I forget exactly what it was: maybe a Japanese yam or sweet potato.

I skinned it, cut it in half and saw this.

Since I don't know what it was supposed to look like, I became frightened and tossed it.

Is this normal and safe to eat?

  1. It looks fine.

    What was troubling? The color or the white spots?

    1. I've never seen that particular hue of sweet potato, but I've seen blue, red, and other colors. Use your nose next time. If it smells inoffensive it's almost certainly totally safe.

      1. The websearch function on your computer is your friend. Do a search on "Asian purple sweet potatoes" & you'll find plenty of info.

          Thank you! I did see one of the pictures that looked like that. Hopefully, that wasn't an example of a bad asian purple sweet potato :-)

            The purple Okinawa sweet potato that I've bought has a pale skin, and an uneven bright purple interior. The purple become more uniform and darker when cooked.

            There's a purple yam from the Philippines that is not in sweet potato family. I've only seen packaged flours and mixes in Asian groceries.

              I know, so rare to find something like this.

                Last time I was able to get some, I had to special order a 40 lb case (to be shared with friends) and it was from Hawaii, not Japan.

            2. Curious to know...what frightened you about the appearance?

                The white spots concerned me:

                I'm used to potatoes having a uniform appearance on the inside. If things start sprouting, growing, rotting, or look moldy or different, I'd be concerned .

                If this is normal, that's fine.
