It definitely could be dangerous @Hooked but I think it’s such a tiny amount in the juice that it only had a tiny affect if that makes sense but it definitely did have an affect.@Paul33 If it initiated an allergic response that could be medically dangerous, couldn't it? I've come across two (I think) coffees, which had warnings on the bottle about nut allergies. One would think that all juice which contains acetyl pyrazine should contain a warning.
