I think I can taste the chemicals put in foods?!?

It's so weird! I get this weird taste with food sometimes... Mostly in red apples and nuts. The whole thing I'm eating ends up tasting like it, and it's so gross. The taste is like... Lavender? It tastes like a florally lavender scent/chemical. Does anyone know if this is a legit chemical I'm tasting in food? Could this thing be harmful? Thanks!
