I agree 100% that we resist consuming alkaloids, at least until we learn to love things like chocolate and coffee.

I just don't taste alkaloids in most sour candy, sorry. I'm not doubting that there are small amounts in some. Probably grapefruit or lemon sour candy has a little alkaloid in it, but it's just a minor constituent. And I'm sure I've had base-free sour candies that made me pucker up.

Why blame a base for the effect of a sweet-sour?
