How long do you have to cook adzuki beans in a pressure cooker before they're edible?

I'm not talking about taste, I'm talking about them not being a health hazard.

I cooked unsoaked adzuki beans for maybe a little less than 20 minutes on the lower pressure setting (don't know the numbers) in my pressure cooker. Then I waited for that cap in the pressure cooker to fall down and put the cooker under cold water, just to be sure, before opening the cooker.

The thing is, I don't usually cook them longer, but I don't open the pressure cooker for 1-2 hours. This time I opened it earlier, didn't think it would make so much difference because the cap was down.

I tried tasting the beans and I like the taste, it's a bit more sour than usual and the texture is a bit harder. I'm used to soft adzuki beans, but these are more like chickpeas, there is a chewing sound when I chew them. Also, they didn't expand as much as when I usually cook them.

I'd like to eat them but I don't know if they're safe, so what I'm asking is, I guess, how long do you have to cook them before they're safe to eat?
