Maybe it is higher %? I know lemon extract is really strong, mostly alcohol and evaporates quickly but I don't recall seeing its effect on eggs. I think vanilla is around 35% alcohol, but I'm not sure about almond. Does it say on the jar?
It depends on the liquid you're mixing it in to. Example; when mixing certain ingredients in veg oil or oil with eggs, the mix will look curdled which is fine and will not effect the recipe.
