This isn't a rant against chemicals in my food. It's more about food additives (both natural and artificial) that taste so bad they render the food inedible or the beverage undrinkable.
Potassium sorbate and sodium benzoate are so bitter they burn my mouth. What the hell are these things and why are they in sodas, bottled tea drinks and some juice drinks? Can't they just leave them out? Trader Joe's sweet tea doesn't use these things and it tastes delicious. Why can't other bottled tea makers follow suit?
Guar gum. Yes, this is a natural substance, but it really doesn't taste very good. I go out of my way to find cream cheese that uses mostly locust bean gum instead.
Natural butter flavor. This gives a nasty, cloying caramel taste that ruins otherwise good boxed cookies.
Any others that ruin processed foods for you? (And no, I don't eat that many processed things, but sometimes, they're unavoidable!)
