Mangosteen seeds turning black and gooey

[petasplit]

I am trying to germinate mangosteen seeds. First I let them soak for 24h then I used paper towel method but my seeds are turning black and gooey. Is it too late to save them or they are gone for good?

Gone for good.

They might have been irradiated.

I  dont know maybe they are irradiated, but I was hoping there is a way to save them.
