I opened up a young coconut today and saw that the flesh inside was purplish in color. The water was also purplish. I used it anyway because when I tasted it it tasted fine. Has anyone else experienced this? Is that normal? I hope I'm not poisoning myself!
You should be fine-- I work in a restaurant where where thwack tons of coconuts and we often get purple ones. They taste just fine and you don't feel any different!
I've heard it's related to the fungicide they dip them in when they are imported into the country. I've cracked open 100's of coconuts in hawaii, central america, and all over south east asia and not once was one purple inside, nor had anyone else seen it outside of imported ones.
